Hello Ranchers

This question is from one of Mock exam

public String makinStrings() {
String s = �Fred�;
s = s + �47�;
s = s.substring(2, 5);
s = s.toUpperCase();
return s.toString();
}
How many String objects will be created when this method is invoked?
A. 1
B. 2
C. 3
D. 4
E. 5
F. 6

Answer is C, my doubt is why cant answer be E

Hmmm... If they are making the distinction I think they are, this is tricky wording that I would not expect on the real exam.

I would say that there are a total of 5 String objects here, but the 2 literals are created when the class is loaded, and this question is asking how many are created when the method is invoked.

(See Strings, Literally.)

when class is loaded how come method local literals are created without explicitly calling the method.I disagree with weber.when class is loaded only static things are initialized(like static variables & blocks)
