This new value should be tested for validity as well. The method should only return to the calling method once a valid value has been obtained, and it should return the valid value.
This is what I have so far:
-
{
-
public int validate (int x, int y, int z)
-
{
-
while((z < x) || (z > y)) {
-
-
// body here
-
}
-
return z;
-
}
-
}
-
I am really bad in Java and have no idea if I am heading in the right direction on this, but how would I make it so I can return the z? Any help would be appreciated
Your control flow logic is fine (assuming x <= y); all you have to do now in the
body of the while loop is tell the user that z is incorrect and read a new value
for it. Check the
Scanner class and read the appropriate article in the
Howtos section (it's all in there).
