String are Immutable (Not Modifiable). If you try to modify
the string it actually creates a new string and the old
string will be then ready for garbage collection.
StringBuilder when instantiated, creates a new string with
predefined capacity and upto that capacity it can
accodomate string without needing to create a new memory
location for the string....i mean it is modifiable and can
also grow as and when needed.
When the string needs to be modified frequently, preferably
use StringBuilder as its optimized for such situations.
