Examples of java.util.Random.nextInt()

java.util.Random.nextInt()
Returns the next pseudorandom, uniformly distributed {@code int}value from this random number generator's sequence. The general contract of {@code nextInt} is that one {@code int} value ispseudorandomly generated and returned. All 2³² possible {@code int} values are produced with(approximately) equal probability.
The method {@code nextInt} is implemented by class {@code Random}as if by:
```
  {@code}public int nextInt()  return next(32); }}
```
@return the next pseudorandom, uniformly distributed {@code int}value from this random number generator's sequence
