Examples of java.util.Random.nextLong()

java.util.Random.nextLong()
Returns the next pseudorandom, uniformly distributed {@code long}value from this random number generator's sequence. The general contract of {@code nextLong} is that one {@code long} value ispseudorandomly generated and returned.
The method {@code nextLong} is implemented by class {@code Random}as if by:
```
  {@code}public long nextLong()  return ((long)next(32) << 32) + next(32); }}
```
Because class {@code Random} uses a seed with only 48 bits,this algorithm will not return all possible {@code long} values. @return the next pseudorandom, uniformly distributed {@code long}value from this random number generator's sequence

            testCompare(1, i);
        }
        Random rand = new Random();
        for (int i = 0; i < 200000; i++) {
            long value = rand.nextLong();
            int scale = rand.nextInt(40) - 20;
            testCompare(value, scale);
        }
