The readResolve method allows a class to replace/resolve the object read from the stream before it is returned to the caller. The following code demonstrates how to create a serializable singleton , using the method.

public class Singleton implements Serializable
{
 static Singleton instance= new Singleton ();

private Singleton ()
 {
 }

protected Object readResolve() 
 {
  return instance;
 }

}
