BigInteger nextProbablePrime() in Java

nextProbablePrime(): This method is available in java.math.BigInteger class of Java.

Syntax:

BigInteger java.math.BigInteger.nextProbablePrime()

This method returns the first integer greater than this BigInteger that is probably prime. The probability that the number returned by this method is composite does not exceed 2^(-100) or (2 power -100).

Note If it returns p, there is no prime q such that this < q < p.

Returns: the first integer greater than this BigInteger that is probably prime.

Throws: ArithmeticException - this < 0 or this is too large.

For Example:

BigInteger bigInteger = new BigInteger("1234")

bigInteger.nextProbablePrime() = > It returns 1237.

Approach

Java

import java.math.BigInteger;

public class BigIntegernextProbablePrime {
    public static void main(String[] args) {

        BigInteger bigInteger = new BigInteger("1234");
        System.out.println(bigInteger.nextProbablePrime());
    }
}

Output:

1237
