Answer / sundarchum

Both the String and StringBuilder class are used to store
strings. One exception is when we change the value in the
string it will create a new String object is creating in
memory and assign the new value.

eg: String name = "Sundar";

A new name object is creating in memory and the
value "Sundar Rahul" is assinging to the newly created
space.

eg: String name = "Sundar Rahul";

But StringBuilder class occupies the same space even if you
change the value.

StringBuilder gives you better performance than String
class when you perform string manipulations like string
concatenation.

You can use StringBuilder's Append() method to use
concatenation and for String use "+".
