Java Program to get number of elements with odd factors in given range

To get number of elements with odd factors in given range, the Java code is as follows −

Example

import java.io.*;
import java.util.*;
import java.lang.*;
public class Demo{
   public static int square_count(int low_range, int high_range){
      return (int)Math.pow((double)high_range,0.5) - (int)Math.pow((double)low_range-1,0.5);
   }
   public static void main (String[] args){
      int low_range = 55, high_range = 1000;
      System.out.print("The number of values with odd factors between a given range of numbers
      is : " + square_count(low_range, high_range));
   }
}

Output

The number of values with odd factors between a given range of numbers is : 24

A class named Demo contains a function named ‘square_count’. This function is defined by passing two integer values as parameters. It returns the number of elements that have odd factors given a specific range. This is done by using the math function ‘pow’. In the main function, the lower range and higher range values are defined and the function ‘square_count’ is called with the lower and higher range values. The relevant message is displayed on the console.
