Java Program Parts

Capitalization does NOT matter with Java.

• True!

• False!

When coding with Java,

System.out.println("Go Java!");

is the same code as

system.out.println("Go Java!");

• True!

• False!

The semicolon

;

is used like a period at the end of a coding sentence.

• True!

• False!

Is     {

        System.out.println("This is a literal print.");

        System.out.print("Yea!");

        System.out.println("Go Java!");

    }

the same code as

  { System.out.println("This is a literal print."); System.out.print("Yea!"); System.out.println("Go Java!"); }

• Yes

• No

Why is    {

        System.out.println("This is a literal print.");

        System.out.print("Yea!");

        System.out.println("Go Java!");

    }

"better" coding than

  { System.out.println("This is a literal print."); System.out.print("Yea!"); System.out.println("Go Java!"); }

• It is a more efficient use of space

• It is much easier to read, change, and debug

Do the spaces and new lines (enters) in the code change anything about what the program does or looks like?

• Yes, the program runs differently because of spaces and enters in the code.

• No, Yes, the program completely ignores spaces and enters in the code.

What does this do?

• It is a list of who made changes and when those changes were made to the program

• Tells the program where to get or send information needed to run the program

• Tells the program where to start running. This part of the code runs first

• The name of the class. This is linked to the ___.java folder with the same name.
