how to change data types, without change variable name JAVA

I have 3 class level1, level2, and player. In player I have script like this

    private level1 play;

(level1 is the name of class, and play is variable). I want to ask, how to change/cast level1 to level2 in player class without change the variable name. Can I do that?

What you need to do is to create an interface. For example, the following will help:

public interface Level { }

public class Level1 implements Level { }

public class Level2 implements Level { }

This way, you can do:

private Level play;

public void start() {
   play = new Level1();

   if(play.isFinished()) {
       play = new Level2();
   }
}

It's just some example code, but I hope you catch my drift.
