OpenVMS Source Code Demos

helloworld

//============================================================================
// title   : HelloWorld.java (for case sensitive sessions)
// or      : HELLOWORLD.JAVA (case-insensitive sessions might see this)
// platform: OpenVMS-8.4 Itanium
// compile : javac  HelloWorld.java
// yields  :        HelloWorld.class
// run     : java  "HelloWorld"		<<-- note the double-quotes
// notes   :
// 1) Java is a case-sensitive language but many parts of OpenVMS are not. If
// your interactive DCL session is initialized as case-insensitive then you
// must double-quote the desired class name in order for the JVM to find then
// execute the desired class
// 2) The filename must exactly match the name found in the public class
// declaration. If change the public class from "HelloWorld" to "Hello_World"
// then you must also modify the filename
//=============================================================================
public class HelloWorld {
   public static void main(String[] args) {
      // Prints "Hello, World" in the terminal window.
      System.out.println("Hello, World");
   }
}
