Document Summary
1 public class helloworld { public static void main(string[] args) { - - - jgrasp exec: java helloworld. ** every java code in this class will begin with public class followed by the title of your document. Don"t forget to include curly brackets { }! ** hit enter and then type public static void main(string[] args) ** now you can type actual lines that will appear when you run the code. System. out. println is the command that tells the system that you are writing on a new line. In the parentheses and quotations, write what you want to print. ** don"t forget the semicolon at the end of your parentheses! In java, when everything is an integer, the answer will also be an integer. ** addition, subtraction, multiplication all work the way we think they do in the interactions pane. ** java cares about type of number and value being used (string, character, number, symbol)
