String s = new String ("abc");

In this case, because we used the new keyword, Java will create a new String object in normal (nonpool) memory, and s will refer to it. In addition, the literal "abc" will be placed in the pool.



What's a nonpool memory? How come there are two object from the above line of code?

Thanks guys!

Java handles String differently. The String object in Java are immutable that means once it has been assigned with some value, it can not be changed.
The paragraph means, when creating new string object it creates 2 copies of it, one on the heap (non-pool) and one on the string buffer pool. When user tries to create another string with value say 'abc' as in this example, then it will first check it in the String buffer pool, if it is available it will not create one more object rather it will assigned that new object to refer to the existing string. If not , it will create again 2 objects as said earlier.
Hope this will clear your doubt.

does this mean that
String s=new String("abc"); and
String s1=new String("abc") actually create 3 objects?

if yes then we are clear on this.....

Even Soumil Shah is also not clear, see his answer, he is creating an object on the buffer pool. While objects are always created on the heap.

Won't we see
Don't take whatever I'm saying offensively, what I meant initially was that if you understood it doesn't mean that everyone understood it. Different people have different levels of knowledge. Suppose I asked a question, a person gives an answer, a third person comes and says "well, that clears it all", then even if I don't understand it, I might hesitate in asking a followup question. I might feel that the third person understood it and I didn't, and if I say that I didn't understand it, then people might think that I'm dumb. So I might stay silent and let the misconception stay in my mind. Just think about it...

No need to say sorry. I would like to remind you that asking your own completely different question in someone else's topic is called a hijack. So try to refrain from that. Punit has already replied to your question, so you've got to be patient...

Oops, I guess i had typed it wrong; instead of String literal pool, i written string buffer.

If you write String literal pool, then also it will be wrong to create an object in String literal pool.
