Using 'Random.nextDouble()' to get random integer
Reports calls to java.util.Random.nextDouble()
that are used to create a positive integer number by multiplying the call by a factor and casting to an integer.
For generating a random positive integer in a range, java.util.Random.nextInt(int)
is simpler and more efficient.
Example:
int getRandomInt() {
return (int) ((new Random()).nextDouble() * SIZE);
}
After the quick-fix is applied:
int getRandomInt() {
return (new Random()).nextInt(SIZE);
}
