hey ,

Thats wonderful clearing the concepts of references & values .
I just want to make things more clear here .

String a="Hello";
String b="HI";

String x=new String("ABC");
String y=new String("XYZ");

Can anyone please tell how many reference and how many object are there in four different expressions?

My Answer would be 4 reference variable and 2 Objects.
a,b,x,y are reference variables of Type String

And There are 2 Objects of Type String . As we have new String("ABC") and new String("XYZ");
here does these Objects have names ? or can we name them ?

-regards

Please don't post a new question on an existing thread. And we require you tell us where that question is from. Separating thread.

I separated those posts because they were unrelated to the original thread.

Please search the fora; there are many questions asked similar to this one.

Actually there are 6.
As Campbell said, search the fora for similar questions if you're not sure why.

In fact, you'd created 4 strings into the pool and two objects in the heap, which refer to two strings in the pool.

You can see the difference if try make any compare:
