Begining with Java
Begining with Java
ghost | 4578 Reads | Ok, so the first thing we need is a Java Compiler so i suggest going to google and type in JCreator (its what I use). Ok now its time to get coding! Java programs are written as classes, and all classes start with a class definition of the form: -public class name, the name must match the file for instance if we have a class name of HelloWorld then the file must be called HelloWorld.java. The class will comprise one piece of code, the main method. The main method must consist of "public static void main(String[] args)" but without the quotes. Now if we put this all together so far we can make a basic HelloWorld program. An example is below:
public class HelloWorld { public static void main(String[] args) { System.out.println("Hello World!"); } } And that is it, Pretty simple huh? We have the class name defined as HelloWorld, the main method which was the public static void main(String[] args), the { } which are used to determine the starts and stops of the block code you wish to enter, and the System.out.println("Hello World!"); which makes a window pop up one one line saying "Hello World!". This is just to get you started and see how easy Java can be to learn. I, myself have been doing it for about a week and im already making decently sized programs (mainly games though). After a while I will add more advanced concepts to help you proceed throughout your Java needs.
Thanks for reading sorry for spelling errors and such -Pyrodude0303

lol. you know what? this is nearly exactly the same as an article i posted on implosion. i know hello world is the starter programme for nearly any language.. but its nearly the same as mine. funny?? mine was more detailed though.
