sum of one-Dimensional array elements in java
One-Dimensional Arrays is one of the basic and the commonly asked questions in the Technical Interviews.
Problem Statement:
Java program to read ‘N’ array elements from One dimensional Array and print the sum of all array elements
Solution Approach:
What we need to consider here
- One-Dimensional Array with array size
- Array Element Iteration
- Add the array element
- Display the sum of all array elements
The below given problem provides the technical solution of reading array N elements and printing the array element sum
package com.java.planforexams.array;
import java.util.Scanner;
public class OneDimArrayElementSum {
public static void main(String args[])
{
// Scanner object for eading User Input
Scanner scan = new Scanner(System.in);
int count,arrayElemntSum = 0;
// Receive the Array Element Count from User
System.out.print("Provide the Array Element Count : ");
// Receive the Array Elements from User.
count = scan.nextInt();
int arrayInputFromUser[] = new int[count];
System.out.println("Enter the elements:");
// Iterate the array elements
for (int incr=0; incr<count; incr++)
{
arrayInputFromUser[incr] = scan.nextInt();
}
for( int arrayElementValue : arrayInputFromUser)
{
arrayElemntSum = arrayElemntSum + arrayElementValue;
}
// print the sum of all array elements.
System.out.println(" ::::Sum of One Dimensional N Array Elements is :::::" +arrayElemntSum);
}
}One-Dimensional Array Program Output:
Provide the Array Element Count : 4
Enter the elements:
23
23
23
23
::::Sum of One Dimensional N Array Elements is :::::92
