Queue of methods in Java

Question

My goal is to have a Queue of method calls contained in a class that extends Thread whose run method pops a method call off of the queue once every 15 seconds. This could be done in a shady way using Strings, ints, or chars in a mammoth switch case, but I was wondering if anyone else has a far more elegant solution to this issue.

Something that would look like this?

public class Potato extends Thread{
    Queue<Methods> methodsQueue = new LinkedList<Methods>();

    public Potato(){}
    run(){
        methodsQueue.poll();//This would execute a method
    }

    //Methods of this class...
}

Answer 1

You can use an interface to wrap the methods you want to call:

public interface MethodWrapper {
  void execute();
}

public class Potato extends Thread{
  Queue<MethodWrapper> methodsQueue = new LinkedList<>();
  public Potato(){}
  run(){
   methodsQueue.poll().execute();
  }

//Methods of this class...
}
