OO Hello World - Xtend

Tweet

The OO Hello World in Xtend, the "the CoffeScript for the JVM", is here!

Xtend is a statically-typed programming language which is tightly integrated with and
runs on the Java Virtual Machine.

You can see the OO Hello World series post here: http://carlosqt.blogspot.com/2010/06/oo-hello-world.html where I give some details on why these "oo hello world series" samples.

Version 1 (Minimal):

The minimum you need to type to get your program compiled and running.

class Greet {
 String name
 new(String name) {
  this.name = name.toFirstUpper
 }
 def salute() {
  println("Hello " + name + "!")
 }
}

// Greet Program
class Program {
 def static void main(String[] args) {
  val g = new Greet("world")  
  g.salute
 } 
}

Version 2 (Verbose):

Explicitly adding instructions and keywords that are optional to the compiler.

package com.series

public class Greet {
 private String name
 public new(String name) {
  this.name = name.toFirstUpper()
 }
 def public void salute() {
  println("Hello " + this.name + "!")
 }
}

package com.series

// Greet Program
public class Program { 
 def public static void main(String[] args) {
  val g = new Greet("world")  
  g.salute()
 } 
}

The Program Output:
