Home >> Java Programs >> Find Sum of N numbers

 In this post, we will learn how to find the Sum of N numbers in Java.

Java Program to Find the Sum of N numbers

Write a Java Program to Find the Sum of N numbers, take all the numbers as input using Scanner, and print the sum of n numbers.

Example 1:
Input: elements: 1,2,3,4,5
Output: 15

Java Program: 

// Java program to find Sum of N numbers

import java.util.Scanner;

public class Main {
	
	public static void main(String[] args) { 
		Scanner sc = new Scanner(System.in);
		
		System.out.println("How many numbers are there?");
		int num = sc.nextInt();
		
		double sum = 0;
		for(int i = 0; i < num; i++) {
			System.out.println("Enter " + (i+1) + " element: ");
			int n = sc.nextInt();
			sum = sum + n;
		}
		
		
		System.out.print("Sum of " + num + " numbers is: " + sum);
		
		sc.close();
	}
}

Output: 

How many numbers are there?
5
Enter 1 element: 
1
Enter 2 element: 
2
Enter 3 element: 
3
Enter 4 element: 
4
Enter 5 element: 
5
Sum of 5 numbers is: 15.0

New Year Chaos Solution - The Coding Shala

Home >> Programming Questions >> New Year Chaos New Year Chaos Problem Solution In this post, you will learn how to solve New Year Chaos Problem and implement its solution in Java. Problem:   It's New Year's Day and everyone's in line for the Wonderland rollercoaster ride! There are a number of people queued up, and each person wears a sticker indicating their initial position in the queue. Initial positions increment from at the front of the line to at the back.  Any person in the queue can bribe the person directly in front of them to swap positions. If two people swap positions, they still wear the same sticker denoting their original places in line. One person can bribe at most two others.  For Example, if n=8 and Person 5 bribes Person 4, the queue will look like this: 1,2,3,5,4,6,7,8. Fascinated by this chaotic queue, you decide you must know the minimum number of bribes that took place to get the queue into its current state. Input:

Richest Customer Wealth LeetCode Solution - The Coding Shala

Home >> LeetCode >> Richest Customer Wealth  In this post, we will learn how to solve LeetCode's Richest Customer Wealth problem and will implement its solution in Java. Richest Customer Wealth Problem You are given an m x n integer grid accounts where accounts[i][j] is the amount of money i​​​​​​​​​​​th​​​​ customer has in the j​​​​​​​​​​​th​​​​ bank. Return the wealth that the richest customer has.  A customer's wealth is the amount of money they have in all their bank accounts. The richest customer is the customer that has the maximum wealth. Example 1: Input: accounts = [[1,2,3],[3,2,1]] Output: 6 Explanation: 1st customer has wealth = 1 + 2 + 3 = 6 2nd customer has wealth = 3 + 2 + 1 = 6 Both customers are considered the richest with a wealth of 6 each, so return 6. Example 2: Input: accounts = [[1,5],[7,3],[3,5]] Output: 10 Example 3: Input: accounts = [[2,8,7],[7,1,3],[1,9,5]] Output: 17 Practice this problem on LeetCode . LeetCode - Richest Customer
