Answer / kanchan
String are read only and immutable. The StringBuffer class
is used to represent characters that can be modified.

Answer / gangabusi
String is immutable, we can not modify the string objects.
if we can create any string object
Ex: String S="Ganga";
here 'S' is string object created in heap memory.
I Want to add Something to S,
String S="Gangadhar";
Here In heap momory one more object is created for 'S',not
overridden.So that each and every updation String create
one new object in heap.
StringBuffer sb="Ganga"
here 'sb' is stringbuffer object created in heap memory.
I Want to add Something to sb,
StringBuffer sb="Gangadhar";
Here In heap momory 'sb' is overridden.So that each and
every updation StringBuffer create an object in stack.
It is mutable and it is Synchronized.(one thread process at
a time)
