Can I add new features into Java like delegate, late binding, etc?

Is there any way that I can add delegate features into Java by a library for example I write add library that add delegate as keyword and handle delegate features like C# 

delegate void SendMessageDelegate(Message message);

void SendMessage(SendMessageDelegate sendMessageDelegateReference)
{
  sendMessageDelegateReference(new Message("hello this is a sample message"));
}
void HandleSendMessage(Message message)
{
  Sender.Send(message);
}

In general, my question is: is there any way to add my new features such as:

  • late binding
  • delegates
  • events like C#
  • properties

by one or more libraries into Java instead of create a new compiler such as groovy or scala?

Solution

  • The simple answer is no. Not with any reasonable amount of work.

    However you can probably implement some or all of those features using the existing Java tools (or find a library that already does it).

    You wouldn't be able to add a new keyword to the language - but it's amazing what you can do with creative use of annotations, generics, etc.

    I've no idea how good it is.
