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));
}   
}
