Note- A number is prime if it is not divisible by any other number except itself.

import java.util.Scanner;

public class PrimeNumber{

public static void main(String[] args){

Scanner in = new Scanner(System.in);

System.out.println("Enter a number greater than 2 which you want to check whether that number is prime or not: ");

int p = in.nextInt();

int i=2;

for(; i<10; i++){

if(p%i==0 && p!=i){

System.out.println("Entered number "+p+" is not a prime number.");

break;

}

}

if(i==10){

System.out.println("Entered number "+p+" is a prime number.");

}

}

}

Enter a number greater than 2 which you want to check whether that number is prime or not:

139

Entered number 139 is a prime number.

**Output**Enter a number greater than 2 which you want to check whether that number is prime or not:

139

Entered number 139 is a prime number.
