Question

Modify the provided code file to create a workout tracking program that lets the user enter (from the console) the distance they ran each day of the week. Store each value into an array of doubles named distances

Answer 1

Answer:

1. import java.util.Arrays;
2. import java.util.Scanner;
4. public class Main {
5.    public static void main(String[] args) {
6.        Scanner input = new Scanner(System.in);
7.        double distances [] = new double[7];
9.        for(int i=0; i < distances.length; i++){
10.            System.out.print("Input running distance for day " + (i+1) + ": ");
11.            distances[i] = input.nextDouble();
12.        }
14.        System.out.println(Arrays.toString(distances));
15.    }
16. }

Explanation:

The solution code is written in Java.

Firstly, create a Scanner object to get user input for running distance (Line 6). Next, declare a distances array and set the array size to 7 because we intend to use this array to hold running distance for 7 days per week.

Next, use the for loop that run for 7 times to repeatedly prompt user to input running distance for each day and store each value to the array distances (Line 9 -12).

At last, display the array to console terminal (Line 14).
