Chapter: Math Class Last Updated: 28-05-2016 12:59:48 UTC

Program:

            /* ............... START ............... */
                
import java.util.*;

public class JavaPronicNumber {
	
	 public static void main(String args[])
	    {
	        Scanner scanner = new Scanner(System.in);
	         
	        System.out.print("Enter a number : ");
	        int n = scanner.nextInt();
	        int k = (int)(Math.sqrt(n));
	        if(k*(k+1)==n)
	            System.out.println(n+" is a Pronic Number.");
	        else
	            System.out.println(n+" is not a Pronic Number.");      
	    }
}
                /* ............... END ............... */
        

Output

Enter a number : 110
110 is a Pronic Number.
 
Enter a number : 73
73 is not a Pronic Number.
 
Enter a number : 342
342 is a Pronic Number.
 
Enter a number : 15
15 is not a Pronic Number.
