Either Naive Example

either_naive.java

// = Right(result) or Left(exception)
Either<Exception, Integer> divideEither(Integer dividend, Integer divisor) {
    return Either.right(dividend / divisor);
}

@Test
public void createEither() {
    System.out.println(divideEither(10,2));
    System.out.println(divideEither(10,0));
}
