6. Write a program that read in a number n and then output the sum of the squares from 1 to n. For example: if n=3, the output should be 14.

package sumofsquares;

import java.util.Scanner;
public class SumOfSquares {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.print("Enter a number: ");
        int n = input.nextInt();

        int sum = 0;
        for (int i = 1; i <= n; i++) {
            sum += i * i;
        }

        System.out.println("Sum of squares: " + sum);
    }
}
