Question

Write a java program that adds up the squares and adds up the cubes of integers from 1 to N, where N is entered by the user:

Upper Limit:

5

The sum of Squares is 55

The sum of Cubes is 225

Do this by using just one loop that generates the integers. DO NOT USE ANY FORMULAS.

Answer 1

All the explanations is given in the comments of the code itself.

Code--

import java.util.*;
public class Program
{
   public static void main(String[] args)
   {
       Scanner sc=new Scanner(System.in);
       int n;
       //prompt the user to enter the upper limit
       System.out.println("Upper Limit:");
       n=sc.nextInt();
      
       int sumSq,sumCube;
       sumSq=0;
       sumCube=0;
      
       //use one for loop to generate the answer
       for(int i=1;i<=n;i++)
       {
           sumSq=sumSq+(i*i);
           sumCube=sumCube+(i*i*i);
       }
       //display the output
       System.out.println("The sum of Squares is "+sumSq);
       System.out.println("The sum of Cubes is "+sumCube);
      
   }
}
