A first application

• Assuming you have the JDK downloaded/installed, create a first Java application:

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

• Save the file as Hello.java.
• Compile the file to Java bytecode:

      javac Hello.java
  

• Run the program:

      java Hello
