Javafx: How to add eventhandlers to another seperate class

I have two buttons within in a pane on the scene. I have added the event handler like this:

    Button reset=new Button ("Reset");
        reset.addEventHandler(MouseEvent.MOUSE_CLICKED,new EventHandler<MouseEvent>(){
        public void handle(MouseEvent event){
        System.out.println("reseting");
        model.reset();
        Play(stage);
    }});

  Button guess=new Button ("Guess");
  guess.addEventHandler(MouseEvent.MOUSE_CLICKED,new EventHandler<MouseEvent>(){
        public void handle(MouseEvent event){
        ArrayList<Integer> FullGuess=new ArrayList<Integer>();
        boolean condition=true;
        for (int y:fullGuess){
           if (y==0){
              condition=false;
           }
       }
   }});

How can I do the event handling part in another class rather than doing it directly in the class as I have done?

Your fragment uses an anonymous class to handle events, but you can promote your anonymous handler to a member of the enclosing class or a separate class having package-private access. In either case, you'll want to pass the required List<Integer> as a parameter.

List<Integer> fullGuess = new ArrayList<Integer>();
…
Button guess = new Button("Guess");
guess.addEventHandler(MouseEvent.MOUSE_CLICKED, new MyEventHandler(fullGuess));

In another file:

class MyEventHandler implements EventHandler<MouseEvent> {

    private final List<Integer> fullGuess;

    public MyEventHandler(List<Integer> fullGuess) {
        this.fullGuess = fullGuess;
    }

    @Override
    public void handle(MouseEvent event) {
        boolean condition = true;
        for (int y : fullGuess) {
            …
        }
    }
}
