List of nextProbablePrime() Examples

Examples of nextProbablePrime()

java.math.BigInteger.nextProbablePrime()
Returns the first integer greater than this {@code BigInteger} thatis probably prime. The probability that the number returned by this method is composite does not exceed 2^-100. This method will never skip over a prime when searching: if it returns {@code p}, there is no prime {@code q} such that {@code this < q < p}. @return the first integer greater than this {@code BigInteger} thatis probably prime. @throws ArithmeticException {@code this < 0}. @since 1.5
