why is ThreadProcessing type used in this snippet?

Question

class Process implements Runnable{
  private ThreadProcessing MIDlet;

  public Process(ThreadProcessing MIDlet){ 
    this.MIDlet = MIDlet;
    System.out.println("Thread Process...");
  }

What is the purpose of using this(ThreadProcessing) here?

Answer 1

ThreadProcessing is the name of the class that extends MIDlet.

... public class ThreadProcessing extends MIDlet implements CommandListener{ private Display display; ...

It's higher up in the code.
