Hi..Java Programmers..!

Can You please tell the use of Singletons in Programming,
And how this would be useful in Applications.

Thanks in Adavance,
Sivanand

using singleton pattern, only a single instance of a class exists which can be used by others. It does not allow creation of new objects of the same class on the heap.

An exaple
public class Singleton{
 
  private Singleton(){
  }

  private static Singleton cInstance;
  public static Singleton getInstance(){
    /** only create an instance if there is none*/
    if(cInstance == null){
       cInstance = new cInstance();
    }
    return cInstance;
  }

  public void yourMethod(){
  }
}
