When you say String is immutable, what do you mean by that?
Say I have String s = "Ness"
s= s+"Technologies";
What will happen? If the value gets appended, then what is
the meaning of immutable here?

Every time a new String objects gets created in this case,
but if assigned value is not same. If assigned, value is
same, then it points to same memory location, even if it is
another variable. For ex;
String s="Test";
String s2="Test";
Now s, s2 points to the same memory location.
