How to get String assigned value

Question

Hi,
As String is immutable and we know that the value of string is not changable.
eg: String abc= new String();
abc = "INDIA";
system.out.println("1st abc : "+abc);
abc=abc.toLowerCase();
system.out.println("2nd abc : "+abc);
As we know as string is immutable the value for the 2nd abc gives us india.As 2nd abc creates a new instance object stores in new memory location.
Then y string is called immutable.It means the value is getting changed.
Is their a way to retrive my original value or first assigned value for abc i.e INDIA.
Thanks
LeoSun.

String abc = "INDIA";
         +-----------+
abc -----+-> "INDIA" |
         +-----------+
abc = abc.toLowerCase();
         +-----------+
abc ---+ |   "INDIA" |
       | |           |
       +-+-> "india" |    
         +-----------+As you see, "INDIA" is not changed, a new String, "india" is created where your variable 'abc' points to.

...Once you change the value of 'abc' (and there exists no reference to it's old value), then no, it's not possible.
Why would you want that?
