Hi all,

public class ChummaEx implements Cloneable
{
   private static ChummaEx moin = null;
   private String mName = null;
   private ChummaEx()
   {}

   public static ChummaEx getInstance()
   {
       if(moin == null)
       {
           createInstance();
       }
       return moin;
   }

   private static void createInstance()
   {
       if(moin == null)
       {
           moin = new ChummaEx();
       }
   }

   public void setName(String name)
   {
       mName = name;
   }

   public String getName()
   {
       return mName;
   }

   public static void main(String args[])
   {
       try
       {
        ChummaEx m1 = ChummaEx.getInstance();
        ChummaEx m2 = (ChummaEx)m1.clone();
           System.out.println(System.identityHashCode(m1));
           System.out.println(System.identityHashCode(m2));
           m1.setName("Moin");

           System.out.println(m2.getName());
           System.out.println(m1.getName());
       }
       catch(CloneNotSupportedException e)
       {
           System.out.println("In Catch");
           e.printStackTrace();
       }
   }
}

Output :

SIngleton has the functionality to create only instance...I was trying
to beak the singleton behavior and after a long research i achieved it
by using the Cloneable interface...

My Questions are:
1. Whether the singleton behavior is overriden by the Cloneable
behavior
2. By implementing the Cloneable interface, how to retain the
Singleton behavior...
3. I tried to use the final key at some place to retain the singleton
behavior....but i failed.
4. Some group mates might have a question in their mind, why i have
used the Cloneable interface....as i already told, i was doing some
research over the singleton...

Kindly help me in this regard
Thanks
Moin
