Challenges

At the end of each larger section, I am going to write down some things you can do to make sure you get what was just gone over.

The rules for this are

• Try to use only the information given up to this point in this book.
• Try not to give up until you've given it a solid attempt

Challenge 1

Write a program that prints your name twice. So if your name is "Jasmine", the output of the program should be this.

Jasmine
Jasmine

Challenge 2

What will this program output when run? Write down your guess and then try actually running it.

void main() {
    System.out.println("A");
    //System.out.println("B");
    System.out.println("C");//
    System.out.println("D");
    /*
    System.out.println("E");
    System.out.println("F");*/
    System.out.println("G");
}

Challenge 3

There are four semicolons in this perfectly functional program. Delete one of them at random and see what the errors you get look like.

How could you use that error to figure out where you might have forgotten to put a semicolon?

void main() {
    System.out.println("Apple");
    System.out.println("Banana");
    System.out.println("Clementine");
    System.out.println("Durian");
}
