CodePorting Converts C# Delegates to Java Instantly

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.

    }
   [B]public[/B] delegate [B]void[/B] Del(string message);

        handler.invoke("Hello World");
 
    }
   [B]public[/B] [B]interface[/B] Del{

   [B]public[/B] [B]static[/B] [B]void[/B] delegateMethod(String message)
   {
