<h2>Answer:</h2><h2></h2>

//import the Random and Scanner classes

import java.util.Random;

import java.util.Scanner;

//Begin class definition

public class ChangeUp {

   

   //Begin the main method

  public static void main(String args[]) {

   //Method to populate the array and print out the populated array

   //Parameter arr is the array to be populated

   public static void populateArray(int [] arr){

       

       //Create object of the Random class to generate the random index

Given that it takes 0.08 ms to travel from one track to the next of a hard drive; that the arm is originally positioned at Track
daser333 [38]

Answer:

Time taken to travel from one track to the next = 0.08ms

Initial track= 15     0

4      (15-4)*(0.08)= 0.88

40     (40-4)*(0.08)= 2.88

35      (40-35)*(0.08)= 0.4

11       (35-11)*(0.08)= 1.92

14       (14-11)*(0.08)= 0.24

7         (14-7)*(0.08)= 0.56

----------------------------------------------

Total seek time=0.88+2.88+0.4+1.92+0.24+0.56=6.88ms

Explanation:

We caculate the seek time for each request, and then add them together to find the total seek time. The final track number for the current request becomes the current track of next request, and this process is repeated till the last request is processed.
