Beginning Programming
Structure of a Programming 

Java is an object oriented programming language, so any program that you write must be inside a class. To quickly get started with running Java applications, there are three basic steps
1. Create a class

public class HelloWorld {

}

2. Create a main method inside the class

public class HelloWorld {
public static void main(String[ ] args) {
}}

3. Write the code for the logic

public class HelloWorld {
/* A program to display the message "Hello World" on standard output */
public static void main(String[] args) {
System.out.println("Hello World!");
}
}

The code above is a complete program to print the message "Hello World". Copy paste the code into scratch pad and run it.
