Use this trick.. If u want to swap a and b., a=a+b; b=a-b; a=a-b; You will get it

It's simple addition and subtraction, just play with those numbers and you will end up getting the answer.

Strings are immutable and you can update the same variable with new values but remember every time you do that, you will create a new object.
