Singleton is a design pattern as well as class.
when we define singleton class it means we can have only one
object of that class.
We cant create multiple objects of that class.
In singleton class, constructor is always private.

eg:
public class Singleton
{
private static Singleton singletonObject = null;
private Singleton()
{
System.out.println("Singleton object created!!!");
}
public static Singleton CreateInstance()
{
if(singletonObject == null)
{
singletonObject = new Singleton();
}
return singletonObject;
}

Now we can get object as:
Singleton ref = null;

ref = Singleton.CreateInstance();
