Java Program to check if count of divisors is even or odd

To check if the count of divisors is even or odd, the Java code is as follows −

Example

 Live Demo

import java.io.*;
import java.math.*;
public class Demo{
   static void divisor_count(int n_val){
      int root_val = (int)(Math.sqrt(n_val));
      if (root_val * root_val == n_val){
         System.out.println("The number of divisors is an odd number");
      }else{
         System.out.println("The number of divisors is an even number");
      }
   }
   public static void main(String args[]) throws IOException{
      divisor_count(25);
   }
}

Output

The number of divisors is an odd number

A class named Demo contains a function named ‘divisor_count’, that checks if the number of divisors of the specific number is an even value or an odd number. In the main function, the ‘divisor_count’ is called with a value defined. Relevant message is displayed on the console.
