Remarks

Returns the next pseudorandom, uniformly distributed long value from this random number generator's sequence. The general contract of nextLong is that one long value is pseudorandomly generated and returned.

The method nextLong is implemented by class Random as if by:

{@code
            public long nextLong() {
              return ((long)next(32) << 32) + next(32);
            }}

Because class Random uses a seed with only 48 bits, this algorithm will not return all possible long values.
