Codeporting C#2java Engine converts C# optional arguments to java in such a way that they remain usable in generated java code which helps developers in a lot of ways. It can be specified from the definition of a constructor, method, indexer or delegate that its parameters are required or they are optional. Arguments must be provided for required parameters but they can be omitted for the optional parameters. If no Argument is sent for the optional parameter its default value is used. CodePorting C#2Java engine automatically handle this overload intelligently.
