  • Try not to give up until you've given it a solid attempt

Challenge 1

Write code that will outputs The number is even if x is an even number.

void main() {
    // Change this variable to different numbers
    // to test your code
    int x = 5;

    // < YOUR CODE HERE >
}

Challenge 2

Make it so that your code from the previous problem will also output The number is odd if the number is odd.

Challenge 3

Write code that will output allowed if the the password variable is equal to "abc123" and not allowed if it isn't.

void main() {
    // Change this variable to different strings
    // to test your code
    String password = "apple";

    // < YOUR CODE HERE >
}

Challenge 4

Write code that will assign the string The number {x} is even to message if x is an even number and The number {x} is odd if x is an odd number.

So if x is 12 the string you should assign The number 12 is even to message.

void main() {
    String message;

    // Change this variable to different numbers
    // to test your code
    int x = 5;

    // < YOUR CODE HERE >

    IO.println(message);
}
