Sum of n numbers in Java

Java Program to display sum of N numbers

In the following question, we are supposed to create a Java Source Code that will ask the user for integer number input N times and display the sum of its inputs altogether.

The standard algorithm will be:

  1. Enter and Store the Number of Integers to be Input.
  2. Run loop N times and keep asking integer input again and again.
  3. Perform Cumulative Sum of each integer given as input.
  4. After the loop terminates, print the result accordingly.
/* Program to Add N numbers user enters and displaying the sum using loop*/
import java.util.*;
class SumOfNumbers
public static void main()
Scanner inp=new Scanner(;
System.out.print("\n Enter Number of Numbers to be Calculated: ");
int n=inp.nextInt();
int i,sum=0,z;

for(i=0;i<n;i++) //Entering N numbers { System.out.print("\n Enter: "); z=inp.nextInt(); sum=sum+z; //Cumulative Sum }

System.out.println("Sum of the numbers: "+sum);

} }


Enter Number of Numbers to be Calculated: 5

Enter: 14

Enter: 25

Enter: 63

Enter: 87

Enter: 10 Sum of the numbers: 199
