Ok, this is driving me nuts! I am programing the board game scrabble for a summer class. One of the requirements is to have multiple JFrames; one for each player. So what I decided to do is create one class named board and display it in two or more JFrames (one for each player). So there is one object board in 2 different JFrames. Now, when I add a tile to the board, it will show up on both frames.

The problem is, when I cover up the JFrames only one board will remain updated.

The board is a class that extends JPanel.

I hope this is clear enough. If not, I will explain it further.

It would help if we could see the code

In other words, if you have two JFrames and add the same JPanel to them. Then you add an item to the JPanel, I want both of the frames to stay updated. In my case, the latest JFrame displays the information of the JPanel and the older frame will lose the graphics if you pass another window over it.

A JComponent (JPanel, JLabel, JButton,....) cannot be in 2 containers at the same time. It will end up into the last one you added it in. So you will need 2 copies (clone) of them

Could someone give me an example of how to clone an object that extends JPanel or of how I could do it in my board class.

I know to add the Cloneable interface and then make the clone method, but I dont know what to return. Thanks in advanced.

Well to give a simple example:

public class Foo implements Cloneable {
  private int ID;
  private String bar;

  public Foo() {
  }

  public int getID() {
    return this.ID;
  }

  public void setID(int ID) {
    this.ID = ID;
  }

  public String getBar() {
    return this.bar;
  }

  public void setBar(String bar) {
    this.bar = bar;
  }

  public Object clone() throws CloneNotSupportedException {
    Foo retVal = new Foo();

    retVal.setID(getID());
    retVal.setBar(getBar());
  
    return retVal;
  }
}

Basically, you create a new object of the type you're cloning, and set all properties to be the same as the original. The API suggests you keep to the following conventions, though it depends on your definition of a copy:

x.clone() != x
&&
x.clone().getClass() == x.getClass()
&&
x.clone().equals(x)
