Prime Number Java Program with Source Code; Using various methods, a Java program can determine whether it is primary or not.

We have included a downloadable zip file at the end of the program so that you may run the following codes.

Example Program:

    

package primenumberjavaprogram;

import java.util.Scanner;

public class PrimeNumberJavaProgram {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
        int count = 0;
        System.out.println("Enter a number ");
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        for (int i = 1; i <= n; i++) {
            if (n % i == 0) {
                count++;

            }
        }
        if (count == 2) {
            System.out.println("prime number ");
        } else {
            System.out.println("Not a prime number ");
        }
    }

}

Output:

//Prime Number Java Program: Sample Code Output

Enter a number 
10
Not a prime number

What is the importance of Prime number program in java using a scanner?

Prime numbers are necessary for communication, and most computer cryptography relies on them. Not only that, but file encryptions use prime numbers as well.

Encryption is used when communicating billing information, logging into an account, or even emailing.

What is the use of the Prime number in the Java program?

Primes are used in a variety of routines in information technology, including public-key cryptography, which is based on the difficulty of factoring large numbers into prime factors.

Prime elements and prime ideals are abstract algebra objects that behave in a generalized way like prime numbers.
