@return The next random boolean.
com.heatonresearch.aifh.randomize.MersenneTwisterGenerateRandom.nextBoolean()
{@inheritDoc}
com.orientechnologies.common.util.MersenneTwisterFast.nextBoolean()
java.security.SecureRandom.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; }}
```
@return the next pseudorandom, uniformly distributed{@code boolean} value from this random number generator'ssequence @since 1.2
java.util.Scanner.nextBoolean()
Scans the next token of the input into a boolean value and returns that value. This method will throw InputMismatchException if the next token cannot be translated into a valid boolean value. If the match is successful, the scanner advances past the input that matched. @return the boolean scanned from the input @throws InputMismatchException if the next token is not a valid boolean @throws NoSuchElementException if input is exhausted @throws IllegalStateException if this scanner is closed
org.apache.commons.math3.random.RandomGenerator.nextBoolean()
Returns the next pseudorandom, uniformly distributed boolean value from this random number generator's sequence. @return the next pseudorandom, uniformly distributedboolean value from this random number generator's sequence
org.apache.commons.math3.random.Well1024a.nextBoolean()
Returns the next pseudorandom, uniformly distributed boolean value from this random number generator's sequence. @return the next pseudorandom, uniformly distributedboolean value from this random number generator's sequence
