How to generalise an adapter class in Java

I have started learning Java and I came across Adapter class. I am trying to use one adapter class for two of my frame classes like below. Is it possible to generalise this adapter class, so many other classes can use this?

import java.awt.*;
import java.awt.event.WindowAdapter;

public class FrameAdopter extends WindowAdapter {
    SampleFrame sf;
    SampleFrame01 sf1;
    FrameAdopter(SampleFrame sf) {
        this.sf=sf; 
    }
}

Without knowing what you are trying to accomplish, you can generify like the following 

public class MyClass<T extends Frame> extends WindowAdapter
{
  T frame;
  public MyClass(T frame)
  {
    this.frame = frame;
  }
}

or in your case 

public class FrameAdopter<T extends SampleFrame> extends WindowAdapter
{
  T sf;
  public FrameAdopter(T sf)
  {
    this.sf= sf;
  }
}
