the string is not modified but rather a new stri g is made and is referenced 1) x="hello" 2) y="world" 3) x=x+" "+y what happens above is that on line 3 we assign a new concatanated string to x, destroying what was there before. so we are not actually adding, but assigning something new constructed from the old

A String is an object of the string class. your addition operator is only an abstraction to indicate the creation of a new String object that will hod the data resulting from the concatenation of two other objects.

Here pineapple is a new string. eg. 2+3=5 here 2 is not modified into 5.
