Singleton Class in Java with example

Singleton Class in Java:

A class said to be singleton class, when we are able to create only one object for a class

To create a singleton class, the class should contain a private constructor and a factory method

Factory Method: if a method provide an object of its own class then it is called factory method and Factory method should be declared as static

Example :

Class Test{

Static sample s1;

  Private Test(){      }

 Void msgMethod(){

System.out.println(“”good morning friends”);

}

Static Test getObject(){

If (s1==null)

   s1=new Test();

return s1;

}

Class Demo {

 public static void main(String args[]){

 Test  t=Test.getObject();

t.msgMethod();

}

}
