9.6 Code Practice: Question 2
- Instructions

Add a method named "sumArray" to your last program that takes an array as a parameter and returns the sum of its values.

-Sample Run

How many values to add to the array:
8
[17, 99, 54, 88, 55, 47, 11, 97]
Total: 468

A method named "sumArray" to your last program that takes an array as a parameter and returns the sum of its values.

Explanation:

The program is used to add a list of arrays.

import java.util.Scanner;

public class MethodsArrays {

   public static int[] fillArray() {

       Scanner scan = new Scanner(System.in);

       int size = scan.nextInt();

       int array[] = new int[size];

       int pos=0;

       for(int i=0; i<array.length; i++) {

           pos=i+1;

           System.out.println("Enter element " + pos);

           array[i]=scan.nextInt();

       }

       return array;

   }

   public static int sumArray(int [] array) {

       int sum=0;

       for(int i=0; i<array.length-1; i++) {

           sum=array[i]+array[i+1];

       }

       return sum;

   }

   }

   public static void printArray(int [] array) {

       for(int i=0; i<array.length; i++) {

           System.out.print(array[i] + " ");

       }

   }

   public static void main(String[] args) {

       fillArray();

       System.out.println("Sum=" + sumArray(array));

       printArray(array);

   }

}

the answer is d.
