CodePorting C#2Java Application is a cloud based converter that 
has accomplished immense popularity because of its broad 
collection of supported C# language constructs. Its powerful 
engine parse and transforms thousand of C# souce code lines to 
java in few seconds.

CodePorting has recently imrpoved its C#2Java engine and now its 
capable of converting C# source code having delegates in it to 
java. In C# programming language, delegate is a form of type-safe 
function pointer which is mostly used for call backs and event 
listener. Unfortunately, there is no delegate construct in Java 
so while converting C# code to Java, C#2Java engine intelligently 
converts the delegates to interfaces with the invoke method call 
by auto generating required code.

Lets take an example of how codeporting engine converts C# 
delegates to java interfaces.

C# Code:

using System.Collections.Generic;
using System;
using System.Linq;
public class Delegate
{
     public static void Main(string[] arg)
     {

         Del handler = DelegateMethod;

         // Call the delegate.
         handler("Hello World");

     }
    public delegate void Del(string message);

    public static void DelegateMethod(string message)
    {
        Console.WriteLine(message);

    }
}

Java Code:

// ********* THIS FILE IS AUTO PORTED FROM C# USING 
CODEPORTING.COM *********

public class Delegate
{
     public static void main(String[] arg)
     {

         Del handler = new Del() {
public void invoke(String message) {
  delegateMethod(message);
}};

         // Call the delegate.
         handler.invoke("Hello World");

     }
    public interface Del{
	 void invoke(String message);
}

    public static void delegateMethod(String message)
    {
        System.out.printf(message);

    }
}
