'Math.random()' cast to 'int'
Warning
New
Last modified: 03 December 2024 Reports calls to 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);

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
