Hashtable uses both the hashCode() and equals() methods. It only calls to the equals() method to confirm that two objects are equal, if they hash to the same bucket.

hi nitin

If you override equals() alone,then each object gets a unique hashcode generated by the hashcode() declared in Object class.

The contract is if two objects have same hashcode alone ,it will check equals() for equality.

Since all objects will now be having unique hascode,your equals() is of no help.

Hope this helps.
