change given string literal value to another value

[mikali singh]

how to change the given string literal value to another value using only one variable and without using string buffer and builder. for example-
String s= "hello dudes" to String s= "hello java DUDES beignners" using only one variable s.

Welcome to JavaRanch!

Strings can't be changed. That's a good concept to drill into yourself early and often. However, you can assign a different String value to the variable s, which may be what you meant. I'm not clear on your assignment though. Are you supposed to transform the first String "hello dudes" to the second based on some rules? Keep in mind we won't do your homework for you, but if you're clearer about the problem, we can point you in the right direction.

Remove the second declaration of the "String s". you can directly assign a new value to variable "s" which was already defined (which will lose its previous reference to "hello dudes" from the constant pool).

What is wrong with

String s =  "hello dudes";
s =  "hello java DUDES beignners";

Technically, neither string has changed. You are now simply pointing the reference variable s to a new, different string.
