between declaring variables before or in loop?

String
            str;
for (int i = 0; i < 10; i++) {
 str = "Hello, World"; // Is
            str created only 1
            time?

}

What
is difference between above and below?
And if they are different, which one is
better?

for (int i = 0; i < 10;
            i++) {
 String str = "Hello, World"; // Is str created 10
            times?
}

Answer

If you didn't write up your example with a
string literal, which is basically a singleton constant, then the answer would be that
in both cases 10 objects are created. In your specific example, no objects
are created.
