how to implement singletun design patteren in struts?
Answer Posted / sk neelofar
public class Sample
{
pubic static Sample s=new Sample();
private sample(){
}//constructor
public static smple getInstance()//static factory method
{
return s;
}//method
}//class
......
Sample s1= Sample.getInstance();
Sample s2= Sample.getInstance();
1.A static method can b called outside the class using clas
name.
2.In this implementation, we used private constructor n a
static factory method to make a class as a singleton class.
3.if we call the getInstance(); of the class for any no. of
times, same object of the class will b returned to the
programmer.
4. the programmer can't create an object pf this class
outside the class, coz it has a private constructor.
