<Tabs>
  <Tab title="Task">
    Here is the next Java program you'll enter, which introduces you to the if statement. Type this in, make it run exactly right and then we'll see if your practice has paid off.

    ```java WhatIf.java theme={null}

    {
        public static void main( String[] args )
        {
            int people = 20;

            int dogs = 15;

            if ( people < cats )
            {
                System.out.println( "Too many cats!  The world is doomed!" );

  <Tab title="Question">
    Assignments turned in *without* these things will not receive any points.

    In this section, you're going to try to guess what you think the if statement is and what it does.

    1. What do you think the if does to the code under it? Put your answer in a comment in the code.
       > Answer : If statement is a conditional statement that runs the code under it if the condition is true.
    2. What is the purpose of the curly braces in the if statement? Answer in a comment.
       > Answer : The curly braces are used to group the code that will be executed if the condition is true.
    3. Change the values of the variables so that *neither* message about cats is printed.
       > Answer : Change the value of `cats` to 20.

## 22. How Old Are You? - [Link](https://programmingbydoing.com/a/how-old-are-you.html)

<Tabs>
  <Tab title="Task">
    Make a program which displays a different message depending on the age given. Here are the possible responses:

    * age is less than 16, say "You can't drive."
    * age is less than 18, say "You can't vote."
    * age is less than 25, say "You can't rent a car."
    * age is 25 or over, say "You can do anything that's legal."

    Here's a sample run. Notice that a person who is under 16 will display three messages, one for being under 16, one for also being under 18, and one for also being under 25.

    **Sample Output:**

    ```bash theme={null}
    Hey, what's your name? Billy_Corgan

    Ok, Billy_Corgan, how old are you? 17

    You can't vote, Billy_Corgan.
    You can't rent a car, Billy_Corgan.

  <Tab title="Question">
    Assignments turned in *without* these things will receive half credit or less.

    In this section, you're going to try to guess what you think the if statement is and what it does.

    1. What do you think else if and else are doing? Answer in a comment.
       > Answer : `else if` is used to check another condition if the previous condition is false. `else` is used to execute the code if all the conditions are false.
    2. Remove the else part at the beginning of one of the else if statements. What difference does that make? Why? Answer in a comment.
       > Answer : If the `else` part is removed, the code will check all the conditions even if one of the conditions is true. The `else` part is used to execute the code if the previous condition is false.

## 25. How Old Are You, Specifically? - [Link](https://programmingbydoing.com/a/how-old-are-you-elseif.html)

<Tabs>
  <Tab title="Task">
    Using `if` statements, `else if`, and `else` statements, make a program which displays a different message depending on the age given.

    | Age          | Message                              |
    | ------------ | ------------------------------------ |
    | less than 16 | `"You can't drive."`                 |
    | 16 to 17     | `"You can drive but not vote."`      |
    | 18 to 24     | `"You can vote but not rent a car."` |
    | 25 or older  | `"You can do pretty much anything."` |

    Note that unlike the [original "How Old Are You" assignment](https://programmingbydoing.com/a/how-old-are-you.html), this program must only display *exactly* one message for a given age and not multiple messages.
    **Sample Output:**

    ```bash theme={null}
    Hey, what's your name? (Sorry, I keep forgetting.) Billy_Corgan
    Ok, Billy_Corgan, how old are you? 17

    You can drive but you can't vote, Billy_Corgan.
    ```

    ```bash theme={null}
    Hey, what's your name? (Sorry, I keep forgetting.) Billy_Corgan
    Ok, Billy_Corgan, how old are you? 14

    You can't drive, Billy_Corgan.
    ```

    You can make up your own messages if you want, but you must have at least four messages, and you must use `else if` statements to make sure only one of the messages is printed for any given age.

## 26. Space Boxing - [Link](https://programmingbydoing.com/a/space-boxing.html)

<Tabs>
  <Tab title="Task">
    Julio Cesar Chavez Mark VII is an interplanetary space boxer, who currently holds the championship belts for various weight categories on many different planets within our solar system. However, it is often difficult for him to recall what his "target weight" needs to be on earth in order to make the weight class on other planets. Write a program to help him keep track of this.

    It should ask him what his earth weight is, and to enter a number for the planet he wants to fight on. It should then compute his weight on the destination planet based on the table below:

    | # | Planet  | Relative gravity |
    | - | ------- | ---------------- |
    | 1 | Venus   | 0.78             |
    | 2 | Mars    | 0.39             |
    | 3 | Jupiter | 2.65             |
    | 4 | Saturn  | 1.17             |
    | 5 | Uranus  | 1.05             |
    | 6 | Neptune | 1.23             |

    So, for example, if Julio weighs 128 lbs. on earth, then he would weigh just under 50 lbs. on Mars, since Mars' gravity is 0.39 times earth's gravity. (128 \* 0.39 is 49.92)

    ```bash theme={null}
    Please enter your current earth weight: 128

    I have information for the following planets:
        1. Venus   2. Mars    3. Jupiter
        4. Saturn  5. Uranus  6. Neptune

    Which planet are you visiting? 2

    Your weight would be 49.92 pounds on that planet.

        1) yes
        2) no

    > 2
    Sorry, "cat" is a string. ints can only store numbers.

    Q3) What is the result of 9+6/3?
        1) 5
        2) 11
        3) 15/3

    > 2
    That's correct!

    Overall, you got 2 out of 3 correct.
    Thanks for playing!

## 28. Modulus Animation - [Link](https://programmingbydoing.com/a/modulus-animation.html)

<Tabs>
  <Tab title="Task">
    In this program, you'll use a loop to draw a simple ASCII-based animation on the screen, and you will use modulus (%) to determine which frame of the animation to show. (You will learn how to create your own loops later.)

    **Files Needed**

    * [ModulusAnimation.java](https://programmingbydoing.com/a/examples/ModulusAnimation.java) - modify and turn in this one
    * [ModulusAnimationWorm.java](https://programmingbydoing.com/a/examples/ModulusAnimationWorm.java) - first example
    * [ModulusAnimationSymbols.java](https://programmingbydoing.com/a/examples/ModulusAnimationSymbols.java) - second example

    If you download, compile and run ModulusAnimationWorm.java it will look roughly like this.

    ```bash theme={null}
    ********
    ```

    (It will look cooler while it's running.)
  </Tab>

  <Tab title="Question">
    Assignments turned in *without* these things will not receive any points.

    1. Add several `if` statements in ModulusAnimation.java so that it draws a little animation of your choosing. You must have a minimum of eight (8) different frames of animation, and it must loop smoothly.
       > Answer :
       ```java ModulusAnimation.java theme={null}

## 32. Twenty Questions... well, actually just Two - [Link](https://programmingbydoing.com/a/twenty-questions.html)

<Tabs>
  <Tab title="Task">
    Make a program which plays a simple game of ~~20~~ 2 Questions. The first question should be "animal, vegetable, or mineral?" Then, the second question should be "is it bigger than a breadbox?" Then, display one of six possible responses, depending on their answers. You can choose what answers to give for each of the six possibilities.

    Here's a suggestion:

    | size \ type                 | animal   | vegetable  | mineral    |
    | --------------------------- | -------- | ---------- | ---------- |
    | **smaller than a breadbox** | squirrel | carrot     | paper clip |
    | **bigger than a breadbox**  | moose    | watermelon | camaro     |

    You will use nested `if` statements to do this.
    **Sample Output:**

    ```bash theme={null}
    TWO QUESTIONS!
    Think of an object, and I'll try to guess it.

    Question 1) Is it animal, vegetable, or mineral?
    > animal

    Question 2) Is it bigger than a breadbox?
    > no

    My guess is that you are thinking of a mouse.
    I would ask you if I'm right, but I don't actually care.
    ```

    ```bash theme={null}
    TWO QUESTIONS!
    Think of an object, and I'll try to guess it.

    Question 1) Is it animal, vegetable, or mineral?
    > mineral

    Question 2) Is it bigger than a breadbox?
    > yes

    My guess is that you are thinking of a truck.
    I would ask you if I'm right, but I don't actually care.

## 33. Choose Your Own Adventure! - [Link](https://programmingbydoing.com/a/choose-your-own-short-adventure.html)

<Tabs>
  <Tab title="Task">
    Make a short "Choose Your Own Adventure" game. The starting room should give the user two choices. Then the second room they travel to should give them two more choices. Finally the third room should give them two choices.

    This means your game will have eight possible "endings". Your game will also have a total of fifteen rooms:

    ```mermaid theme={null}
    graph TD;
        R1-->R2;
        R1-->R3;
        R2-->R4;

        R6-->E6;
        R7-->E7;
        R7-->E8;
    ```

    You must use nested `if` statements to do this.
    **Sample Output:**

    ```bash theme={null}
    WELCOME TO MITCHELL'S TINY ADVENTURE!

    You are in a creepy house!  Would you like to go "upstairs" or into the
    "kitchen"?
    > kitchen

    There is a long countertop with dirty dishes everywhere.  Off to one side
    there is, as you'd expect, a refrigerator. You may open the "refrigerator"
    or look in a "cabinet".
    > refrigerator

    Inside the refrigerator you see food and stuff.  It looks pretty nasty.
    Would you like to eat some of the food? ("yes" or "no")
    > no

    You die of starvation... eventually.
    ```

    ```bash theme={null}
    WELCOME TO MITCHELL'S TINY ADVENTURE!

    You are in a creepy house!  Would you like to go "upstairs" or into the
    "kitchen"?
    > upstairs

    Upstairs you see a hallway.  At the end of the hallway is the master
    "bedroom".  There is also a "bathroom" off the hallway.  Where would you like
    to go?
    > bedroom

    You are in a plush bedroom, with expensive-looking hardwood furniture.  The
    bed is unmade.  In the back of the room, the closet door is ajar.  Would you
    like to open the door? ("yes" or "no")
    > no

    Well, then I guess you'll never know what was in there.  Thanks for playing,
    I'm tired of making nested if statements.

    Using `if` statements with compound conditions (like `&&`), make a guessing game of two questions similar to the [Twenty Questions assignment](https://programmingbydoing.com/a/twenty-questions.html).

    However, this time you must accomplish it using `if` statements with compound conditions and you *must not* use `else if` or `else` or nested `ifs`.

    * Question 1: Does it belong inside or outside or both?
    * Question 2: Is it alive?

## 36. BMI Categories - [Link](https://programmingbydoing.com/a/bmi-categories.html)

<Tabs>
  <Tab title="Task">
    (This assignment was suggested by Joel H in 2012.)

    The body mass index (BMI) is commonly used by health and nutrition professionals to estimate human body fat in populations. It is computed by taking the individual's weight (mass) in kilograms and dividing it by the square of their height in meters.

    Start with the [BMI Calculator](https://programmingbydoing.com/a/bmi-calculator.html) you wrote previously (BMICalc.java). Then use some `if` statements to show the category for a given BMI.

    | BMI            | Category      |
    | -------------- | ------------- |
    | less than 18.5 | underweight   |
    | 18.5 to 24.9   | normal weight |
    | 25.0 to 29.9   | overweight    |
    | 30.0 or more   | obese         |

    <Note>
      Although BMI is a very good estimate of human body fat, the formula doesn't work well for athletes with a lot of muscle, or people who are extremely short or very tall. If you are concerned about your BMI, check with your doctor.
    </Note>

    **Sample Output:**

    ```bash theme={null}
    Your height in m: 1.75
    Your weight in kg: 73

    Your BMI is 23.83673
    BMI Category: normal weight
    ```

    It doesn't matter whether you input the values in metric (kilos and meters) or Imperial measurements (feet/inches and pounds).

    ```bash theme={null}
    Your height in inches: 69
    Your weight in pounds: 220

    Your BMI is 32.5

## 37. Gender Game - [Link](https://programmingbydoing.com/a/gender-game.html)

<Tabs>
  <Tab title="Task">
    Make a program which displays an appropriate name for a person, using a combination of nested `ifs` and compound conditions. Ask the user for a gender, first name, last name and age.

    If the person is female and 20 or over, ask if she is married. If so, display "Mrs." in front of her name. If not, display "Ms." in front of her name. If the female is under 20, display her first and last name.

    If the person is male and 20 or over, display "Mr." in front of his name. Otherwise, display his first and last name.

    Note that asking a person if they are married should *only* be done if they are female and 20 or older, which means you will have a single `if` and `else` nested inside one of your `if` statements.

    Also, did you know that with an `if` statement (or `else`), the curly braces are **optional** when there is only one statement inside?
    **Sample Output:**

    ```bash theme={null}
    What is your gender (M or F): F
    First name: Kim
    Last name: Kardashian
    Age: 32

    Are you married, Kim (y or n)? y

    Then I shall call you Mrs. Kardashian.
    ```

    ```bash theme={null}
    What is your gender (M or F): F
    First name: Marisa
    Last name: Tomei
    Age: 48

    Are you married, Marisa (y or n)? n

    Then I shall call you Ms. Tomei.
    ```

    Notice that in the example below, we *never even ask the marriage question*, because she is under 20 and so her marital status doesn't change what we call her.

    ```bash theme={null}
    What is your gender (M or F): F
    First name: Chloe
    Last name: Moretz
    Age: 16

    Then I shall call you Chloe Moretz.
    ```

    ```bash theme={null}
    What is your gender (M or F): M
    First name: Daniel
    Last name: Radcliffe
    Age: 23

    Then I shall call you Mr. Radcliffe.
    ```

    ```bash theme={null}
    What is your gender (M or F): M

## 38. compareTo() Challenge - [Link](https://programmingbydoing.com/a/compareto-challenge.html)

<Tabs>
  <Tab title="Task">
    Write a program that compares several `Strings` using the `compareTo()` method. You should display the `Strings` and display the integer that `compareTo()` gives you.

    You must have five examples which result in a number less than 0, five examples which result in a number greater than 0, and two examples which give you exactly 0. This means you need a total of twelve examples.

    You may **not** just flip the `Strings` around; you must have twelve different examples.

    Here's an example:

    ```java CompareToChallenge.java theme={null}
    System.out.print("Comparing \"axe\" with \"dog\" produces ");
    int i = "axe".compareTo("dog");
    System.out.println(i);

    System.out.print("Comparing \"applebee's\" with \"apple\" produces ");
    System.out.println( "applebee's".compareTo("apple") );
    ```

    **Sample Output:**

    ```bash theme={null}
    Comparing "axe" with "dog" produces -3
    Comparing "applebee's" with "apple" produces 5
    ```
  </Tab>

  <Tab title="Answer">
    ```java CompareToChallenge.java theme={null}
    public class CompareToChallenge
    {

            System.out.print( "Comparing \"axe\" with \"dog\" produces " );
            System.out.println( "axe".compareTo("dog") ); // -3
            System.out.print( "Comparing \"apple\" with \"banana\" produces " );
            System.out.println( "apple".compareTo("banana") ); // -1
            System.out.print( "Comparing \"apple\" with \"dog\" produces " );
            System.out.println( "apple".compareTo("dog") ); // -3
            System.out.print( "Comparing \"apple\" with \"elephant\" produces " );
            System.out.println( "apple".compareTo("elephant") ); // -4
            System.out.print( "Comparing \"apple\" with \"zebra\" produces " );

            System.out.print( "Comparing \"zebra\" with \"apple\" produces " );
            System.out.println( "zebra".compareTo("apple") ); // 25

            System.out.println( "\n2 Produces 0:" );

## 39. Alphabetical Order - [Link](https://programmingbydoing.com/a/alphabetical-order.html)

<Tabs>
  <Tab title="Task">
    Make a program that asks for the last name of the user. Depending on their last name, make a statement about how long they have to wait during roll call. You need to use `else ifs` to make sure only one statement gets printed.

    Once you understand how `compareTo()` works, this is a pretty straightforward assignment, much like [How Old Are You, specifically](https://programmingbydoing.com/a/how-old-are-you-elseif.html), except that it uses `Strings` instead of `ints` and so you must use the `compareTo()` method.

    * name is `"Carswell"` or before: say "you don't have to wait long"
    * name is `"Jones"` or before: say "that's not bad"
    * name is `"Smith"` or before: say "looks like a bit of a wait"
    * name is `"Young"` or before: say "it's gonna be a while"
    * name is after `"Young"`: say "not going anywhere for a while?"

    **Sample Output:**

    ```bash theme={null}
    What's your last name? Stephanopolis
    It's going to be a while before we get to you, "Stephanopolis".
    ```

## 40. The Worst Number-Guessing Game Ever - [Link](https://programmingbydoing.com/a/the-worst-number-guessing-game-ever.html)

<Tabs>
  <Tab title="Task">
    Write a program that plays an incredibly stupid number-guessing game. The user will get one try to guess the secret number. Tell them if they got it right or wrong, and if they got it wrong, display what the secret number was.

    You must store the secret number in a variable, and use that variable throughout. The secret number itself must not appear in the program at all, except in the one line where you store it into a variable.

    I know it will be the same number every time the game is played.

    **Sample Output:**

    ```bash theme={null}
