String is mutable

We heared that many times but most of us not know what that means..,

I am trying to explain what is mutable and what is immutable..

Mutable and immutable are mearly just eglish words as the meaning of these words

'Can change' and 'Cannot change'.

Like that a sting is immutable

that means a if we define a stirng its will create a

sting object ,if we change the value of our sting then

also create another sting object. If we try to concat it will also create

another string object.
