Java Program To Sum the elements of the Array Entered By The User
In this Java Program, we sum up all the elements of the array entered by the user.
Array is a data structure consisting of collections of elements each identified by atleast one array index or key.
E.g. If you want to store 5 numbers in an array,
datatype arrayname [arraysize];
int a[5];
Step 1 : Import java.util.Scanner Class
Step 2 : Create the object of the Scanner Class
Step 3 : Create and Initialize array
Step 4 : Create variable sum and initialize it to zero
Step 5 : Ask the user to enter the elements by using println method
Step 6 : Apply for loop where i is equal to 0, i is less than 10 and increment i
Step 7 : Store the user entered elements in the array of i
Step 8 : Apply advanced for loop where num : array
Step 9 : Add sum and num and save its result in the variable sum
Step 10 : Print the Sum of the array elements.
Program :
import java.util.Scanner;
public class SumArray2
{
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
int[] array = new int[10];
int sum = 0;
System.out.println("Enter the elements:");
for(int i = 0; i<10; i++)
{
array[i] = sc.nextInt();
}
for(int num : array)
{
sum = sum + num;
}
System.out.println("Sum of array elements is:"+sum);
}
}
Output :
Enter the elements:
1
2
3
4
5
6
7
8
9
10
Sum of array elements is:55
