Singelton Design Pattern

package com.sun.spring.mvchello;

public class Singelton {
private static Singelton singletonInstance;
private Singelton(){

}
public static Singelton getInstance(){
if(singletonInstance == null){
singletonInstance = new Singelton();
}
return singletonInstance;
}

}

package com.sun.spring.mvchello;

/**

 * Hello world!

 *

 */

public class App 

{

public static void main(String args[]){

Singelton singelton1 = Singelton.getInstance();

Singelton singelton2 = Singelton.getInstance();

System.out.println("Singelton1"+singelton1);

System.out.println("Singelton2"+singelton2);

System.out.println("=="+(singelton1 == singelton2));

System.out.println("equals"+singelton1.equals(singelton2));

}
