The first step to getting familiar with a new language is to write a simple “Hello World” program.
To create a "Hello World" program in Java, just follow these simple steps:
* Create a file (i.e., `helloworld.java`).
* Make sure that the outer class is of the same name as the filename, ​without extension (i.e., *helloworld*).
* Now write the main method for the *helloworld* class.

# Code
In the code below, the same steps are followed for the Hello World program.
>Remember, every program in Java consists of a *main* method with the same signature, ​i.e.,  `public static void main(String []args)`.​

class HelloWorld {
    public static void main( String []args ) {
        System.out.println( "Hello World!" );
    }
}
