Hi All,
Say I have the following:
String a = "Hello"; so a is refer to a particular area in the memory that holds String class, rihgt?
Now whe I mak some change:
a=a.substring(0,3)+"p!"; Does a now refer to a new String class that holds the world "help" or it refers to the old one?
Thank u in advance

a is now referring to a different string. You can check:
String a = "Hello";
String b = a; //b and a refer to the same object
a=a.substring(0,3)+"p!";
System.out.println(a==b); //false

It refers to a new instance of the String class.
As an aside, the new instance may refer to the same char array as the first instance.
