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();

}

}
