A Few Java Factoids – Part 1

A few basic facts about Java.

This is the main method that you’re going to use every time you run a Java program, unless you’re making just a class file, in which case you will not need the wholeΒ public static void main (String[] args), but you will still need [class] with the class name next to it.

Brackets or the curly braces (what have you) that look like thisΒ { }Β are required at the beginning and end of each method you’ve used to indicate when you’ve finished the programming statements for that particular method.

Finally, for eachΒ System.out.println("Text");Β that you have there always needs to be aΒ ;Β at the end. Always! So get used to it!

If you decideΒ NOTΒ to put the stupidΒ ;Β at the end of your output statements, you WILL get anΒ ERROR.

Also, in case you were wondering, with most IDEs or Integrated Development Environments, there is syntax highlighting which makes it easier to understand what’s going on by adding color to the types of different texts.

For example, with the Strings involved in the program, they are the color [red]. With the comments involved in the program, they are the color [gray]. Different methods are highlighted in [blue].

So that’s pretty much it for the super duper basics of any Java program.

Remember, you gotta have your:\

  1. main methodΒ public static void main (String[] args)\
  2. curly bracesΒ {}\
  3. semi-colonsΒ ;\
  4. comments to explain what the heck you’re doing in the program such as [//single-line stuff] or [/*multi-line stuff*/]

Get it? Got it? Good.
