Question

Lab Topics • The basics of Array object Use the following Coding Guidelines • When declaring a variable, you usually want to initialize it. Remember you cannot initialize a number with a string. Remember variable names are case sensitive. Use tabs or spaces to indent code within blocks (code surrounded by braces). Use white space to make your program more readable. Use comments after the ending brace of classes, methods, and blocks to identify to which block it belongs. Problem Description For this lab, you will 1. create a basic Array of numbers, 2. fill in the elements of that array by prompting the user for inputs, 3. display the elements of the array to the user, and then 4. calculate and display the sum of those array elements.

Answer 1

abc

CODE TEXT

package com.abc.example;

import java.util.Scanner;

public class Lab8 {

public static void main(String[] args) {

int arraySize;

double sumOfArray = 0.0;

Scanner scan = new Scanner(System.in);

//REQUESTING ARRAY SIZE FROM USER

System.out.println("How many elements in the array?");

arraySize = scan.nextInt();

//DECLARING ARRAY

double[] array = new double[arraySize];

//FILLING THE ARRAY

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

System.out.println("Please enter next value: ");

array[i] = scan.nextDouble();

}

//DISPLAY THE ARRAY

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

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

}

//SUMMATION OF ARRAY ELEMENTS

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

sumOfArray = sumOfArray + array[i];

}

System.out.println("\nThe sum of array elements is " + sumOfArray);

}

}
