Math.random()
which are immediately
cast to int
.
Casting a double
between 0.0
(inclusive) and
1.0
(exclusive) to int
will always round down to zero. The value
should first be multiplied by some factor before casting it to an int
to
get a value between zero (inclusive) and the multiplication factor (exclusive).
Another possible solution is to use the nextInt()
method of
java.util.Random
.
Example:
int r = (int)Math.random() * 10;
After the quick fix is applied:
int r = (int)(Math.random() * 10);
