Answer Posted / amit sharma

singleton is a design pattern. in this per application only
one object should exist.we implement it as follows:

public class abcd
{
private static abcd instance=null;
protected abcd()
{
//only to defeat instantiation;
}
public static abcd getInstance()
{
if(instance==null)
{
instance=new abcd();
}
return instance;
}
