How many Objects created??

Question

Hi Friends,
I am really confused with this question,can someone please tell me how many objects would be created by the following code??My answer is two("java" on the heap and the normal new String() Object),am i right???
public class Objects{  
public static void main(String[] args)    {   
    String one = "Java";    
    String two = "Java";   
    String three = "J" + "a" + "v" + "a"; 
    String four = new String("Test");  
}Thanks

Answer 1

Probably not, since all the operands are string
literals. The compiler probably sees that and instead
generates the same bytecode that it would have if it
had been coded as: "Java" in the first place. But
again, still stupid and pointless.just what i wanted to say but was a bit slow. maybe it's stupid and pointless,
but for grins, i am attaching the constants pool from the class file that was
obtained by compiling the code in post 1 with Sun's compiler. I don't see any
"J" or "a" or .........
