Examples of java.util.Random.nextBoolean()

java.util.Random.nextBoolean()
Returns the next pseudorandom, uniformly distributed {@code boolean} value from this random number generator'ssequence. The general contract of {@code nextBoolean} is that one{@code boolean} value is pseudorandomly generated and returned. Thevalues {@code true} and {@code false} are produced with(approximately) equal probability.
The method {@code nextBoolean} is implemented by class {@code Random}as if by:
```
  {@code}public boolean nextBoolean()  return next(1) != 0; }}
```
