help with simple programming question

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

Code:

---

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:

Code:

---

    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,

Jos

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.
