Hi..

Mutable & Immutable

1)string is immutabel.
i.e. whenever you create any changes to a string a new
object is created in memory.
2)StringBuilder has advantage String
To overcome this the stringBuilder is provided we can make
ammendments to the stringBuilder object without creating a
new object. Therefore whenever a lot operations are to be
made on a string then StringBuilder should be used in place
of String.
