help with simple programming question

[eezilyBefuddled]

I hope this question isn't too simple or dumb...

int x = 2;
int y = "WKD".hashCode() % 3000;
int z = "WWI".hashCode() % 3000;
for (int i = 0; i <= z; i++)
  a = (x ^ i) % y;
return z;

Can someone please tell me what value is returned for z? Thanks!

Why don't you use System.out.println(z); and find out?

I was hoping that someone here could tell me the (correct) answer... :)

It all depends on what the hasCode() method in the String class returns; here it is:

    public int hashCode() {
	int h = hash;
	if (h == 0) {
	    int off = offset;
	    char val[] = value;
	    int len = count;

            for (int i = 0; i < len; i++) {
                h = 31*h + val[off++];
            }
            hash = h;
        }
        return h;
    }

b.t.w. you can find this in the src.zip file stored in your JDK directory.

kind regards,

You think we keep the value of something like:
"WWI".hashCode()
in our heads?

Well, maybe Jos does, but he's strange.

You were asking for a handout, I told you how to figure it out.

You realise that forced me to go and check, don't you?
You swine!

Sound like something my dad would say... of course, he was usually right. :eek:
