Learn Java programming tutorial lesson 1 - First Program What is Java? Java is an object-oriented programming language which was developed by Sun Microsystems. Java programs are platform independant which means they can be run on any operating system with any type of processor as long as the Java interpreter is available on that system. What you will need You will need the Java software development kit from Sun's Java site . Writing your first Java program You will need to write your Java programs using a text editor. public class Hello This creates a class called Hello. We must now create the main method which is the section that a program starts. public static void main(String[] args) The word public means that it is accessible by any other classes. static means that it is unique. void is the return value but void means nothing which means there will be no return value. main is the name of the method. You will see that the main method code has been moved over a few spaces from the left. Here is how you print the words Hello World on the screen:

LE DIFFERENZE TRA L’ITALIA E LA NORVEGIA, IL PAESE SENZA DEBITO PUBBLICO. « Il Corsivo Quotidiano Cosa deve fare l’Italia per uscire dalla crisi? Semplicemente essere la Norvegia.
