Answer / vikrant
Once a string object is created no changes can be made to
it. If a string is modified in code a new object will be
created. That is why string is immutable

Answer / rakesh soni
Any Program have 'Performance' and 'Memory' issue.
1. If you want to save your 'memory' then use the 'String'
class but 'Performance' will be decrease, because every time
new object create and old object memory collect by Garbage
Collector, so performance decrease.
And
2. If you want 'Performance', than use 'StringBuffer' or
'StringBuilder' object. These class's object consume more
memory but not create new object, so 'Performance' will
increase but with memory overhead.
So take decision according your code and issue. :)
