Java BigInteger .isProbablePrime (int certainty)
Syntax
BigInteger.isProbablePrime(int certainty) has the following syntax.
public boolean isProbablePrime(int certainty)
Example
In the following code shows how to use BigInteger.isProbablePrime(int certainty) method.
//ww w . java 2 s .co m
import java.math.BigInteger;
public class Main {
public static void main(String[] args) {
// assign values to bi1, bi2
BigInteger bi1 = new BigInteger("7");
BigInteger bi2 = new BigInteger("9");
// perform isProbablePrime on bi1, bi2
Boolean b1 = bi1.isProbablePrime(1);
Boolean b2 = bi2.isProbablePrime(1);
Boolean b3 = bi2.isProbablePrime(-1);
System.out.println(b1);
System.out.println(b2);
System.out.println(b3);
}
}
The code above generates the following result.
