Java
java.math.BigInteger class contains a method

**nextProbablePrime ()**to check the primality of a number.
import java.math.BigInteger;

public class NextPrime {

public static void main(String[] args) {

int number = 83;

Long nextPrime =

*nextPrime*(number);
System.

*out*.println(nextPrime + " next prime to " + number);
}

/**

* method to find next prime

* @param number

* @return boolean

*/

private static Long nextPrime(int number) {

BigInteger bValue =
BigInteger.

*valueOf*(number);
/**

* nextProbablePrime method used to generate next prime.

* */

bValue =
bValue.nextProbablePrime();

return Long.

*parseLong*(bValue.toString());
}

}

Output:

89 next prime to 83
