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.
Java is a strongly typed programming language. This means that every variable must have a data type associated with it. For example, a variable could be declared to use one of the eight primitive data types: byte, short, int, long, float, double, char or boolean. A good analogy for a variable is to think of a bucket.
