IL overtime laws only require overtime after an employee has worked all 40 hours in the week, not if they've just worked more than 8 hours in a day. Employers are not required to pay overtime according to Illinois overtime laws for having employees work on holidays or Sundays.
The java.util.Arrays.fill(byte[] a, byte val) method assigns the specified byte value to each element of the specified array of bytes.
In Java, arrays internally use integers (int not Integer) for index, the max size is limited by the max size of integers. So theoretically it is 2^31-1 = 2147483647, which is Integer.MAX_VALUE. But in recent HotSpot JVM it has been observed that the max size of array can be Integer.MAX_VALUE - 5.
