Question

Gery blocks of code (lines 1-13 & 16-end) can NOT be edited. 

JAVA code needs to be added inbetween the grey blocks of code. 

Given the integer array yearlyMiles with the size of NUM_ELEMENTS, write a for loop to output the integers in the first half of
yearlyMiles in reverse order. Separate the integers with a dash surrounded by spaces ("- ").
Ex: If the input is 110 46 31 69 103 83 70 60, then the output is:
69 31 46 110
1 import java.util.Scanner;

public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
final int NUM_ELEMENTS = 8;
int[] yearlyMiles = new int [NUM_ELEMENTS];
int i;
}
for (i = 0; i < yearlyMiles.length; ++i) {
yearlyMiles [i] = scnr.nextInt ();
}

Expert Solution
Step 1: Algorithm
  1. Import the Scanner class to enable user input.

  2. Define a class named MileData.

  3. In the main method:

    a. Create a Scanner object scnr to read input from the console.

    b. Declare a constant NUM_ELEMENTS with a value of 8, representing the number of elements to read.

    c. Create an integer array yearlyMiles with a length of NUM_ELEMENTS to store the user input.

    d. Declare an integer variable i for iteration.

    e. Start a for loop with i initialized to 0, running until i is less than the length of yearlyMiles:

    i. Inside the loop, read an integer from the user using scnr.nextInt() and store it in the yearlyMiles array at index i.

    f. After the loop, a filled yearlyMiles array will contain the user's input.

    g. Start a second for loop with a new integer variable i initialized to NUM_ELEMENTS / 2 - 1, running as long as i is greater than or equal to 0:

    i. Inside this loop, print the element in the yearlyMiles array at index i.

    ii. Check if i is greater than 0, and if so, print a hyphen ("-") as a separator.

    h. After the loop, a reverse order of the first half of the yearlyMiles array is printed with hyphens between the elements.

  4. Finally, print a newline character to end the output.
