Write a program to find and display the sum of the following series:
Program 13
s = 1+4+9+16….nth term
1 import java.util.*;
2 class prog_loop5
3 {
4 public static void main()
5 {
6 Scanner sc = new Scanner (System.in);
7 int n,i;
8 double sum=0.0;
9 System.out.println("Enter n terms: ");
10 n=sc.nextInt();
11 for (i=1; i<=n; i++)
12 sum=sum + (i*i);
13 System.out.println("Sum of the Series :"+sum);
14 }
15 }
You will get the following output:
