how to implement singletun design patteren in struts?..

Answer / 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.

Answer / shaik baji

Singletun design patteren means we can't create more than
one object for that class which follws Singletun design
pattern.

We can implement it by using one "private" constructor and
one Factory mathod as like follows:

class Sample
{
public static Sample s = new Sample();

private Sample()//constructor
{

}
public static Sample getInstance()//static factory
method
{
return s;
}
}

public class SingleTun
{
public static void main(String arg[])
{
Sample s1= Sample.getInstance();
Sample s2= Sample.getInstance();

}

}
