singleton

hi friend,

import java.io.*;

public class SingletonExam implements Serializable {

public static SingletonExam single;

protected SingletonExam(){
// Exists only to thwart instantiation.
}

private Object readResolve(){
return single;
}

public static void main(String args[]){
System.out.println("welcome back");
single = new SingletonExam();
single.readResolve();

}
}
