Hi,
I don't understand the answer to this question...

Question 91
Given:
11. public String makinStrings() {
12. String s = “Fred”;
13. s = s + “47”;
14. s = s.substring(2, 5);
15. s = s.toUpperCase();
16. return s.toString();
17. }

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: C

Can someone explain why it's 3?

Thanks.

Thanks

I will search in future before posting.

I had no idea that it would be such a common question!
