Hi Narendra,
This sort of question has been discussed hundreds of times. If you use
the search facility of JavaRanch, you will find so many interesting discussion
on this.
Hint: When you use new operator to create
String object, object is created
at run time. Without using "new" you call compile time created String object.
Objects created with "new", gives false result when you use == to compare
them even if the content is same. Because == compares references of the
objects.
Thanks,
