Java: Is there support for macros?

Question

I am just curious on how people solve this. I often write the same type of code all the time. For instance:

new Thread() {
   //...
   //...
   //...
   //Change         


        

Answer 1

In the case of a Thread, you can pass any object that implements Runnable to its constructor.

So, the solution is to create your own class:

public class MyClass implements Runnable {
    void run() {
        // change this line
    }
}

Unfortunately, run isn't static, so you'll have to create an instance of MyClass first:

new Thread(new MyClass()).start();

You could also add variables to MyClass and a constructor so you can pass arguments to it.

Edit: If you need more than just the start method, you can also subclass Thread itself.
