The answer to this question is given below in this explanation section.

Explanation:

          "difference between cd-r, cd-rw and cd-rom​"

CDs are also known as WORM discs,for "write once Read many".A re writable version based on excitable crystals and known as CD-RW was introduced in the mid 1990s because both CD-R and CD-RW recorders originally required a computer to operate  they had limited acceptance of use as computer software.

  A compact Disc Read only memory (CD-ROM) is a read only disc.A compact disc Re-writable (CD-RW) is an erasable disc that can be reused.The data  on a CD-RW disc can be erased and recorded over numerous times.CD-RW may not be readable outside of the drive it was created in.

cd-r :

          CD-R is a digital optical disc storage format.A CD-R disc is compact disc that can be written once and read arbitrarily many times.

          CD-R stand for" compact disc" Record-able .CD-R disc are blank CDs that can record data written by a CD burner.The word "record-able" is used because CD-R are often used to record audio,Which can be play back by most CD players.

cd-rw:

           CD-RW compact disc re-writable is a digital optical disc,storage format introduced in 1997.A CD-RW compact disc can be written read erased and re-written.

in this case of CD-RW the writing laser makes permanent marks in a layers of dye polymer in the disc.CD rewrite-able discs in a similar fashion,except that the change to the recording surface is revers able.

cd-rom:

         CD-Rom observation of compact disc read only memory type of computer memory in the form of compact disc that is read by optical means.A CD-ROM drive uses a low power laser been encoded in the form of tiny pits on a optical disk.The "ROM" part of the term means the data on the disc "read only memory" or cannot be altered or erased.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       int totalValues = 0;

       int totalTaxes = 0;

       int count = 0;

       while(true) {

           int lotNumber, value;

           double tax;

           System.out.println("Would you like to add an Entry: 1=Yes 0=No");

           int answer = in.nextInt();

           if (answer == 1) {

               System.out.println("Please enter lot number: ");

               lotNumber = in.nextInt();

               if ((lotNumber >= 0) && (lotNumber <= 999999)) {

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

                   value = in.nextInt();

                   tax = value * 0.05;

                   System.out.println("Lot Number: " + lotNumber);

                   System.out.println("Property Value: " + value);

                   System.out.println("Property Tax: " + tax);

                   totalTaxes += tax;

                   totalValues += value;

                   count += 1;

               } else {

                   System.out.println("Invalid Lot Number");

               }

           } else {

               break;

           }

       }

       int average = totalTaxes / count;

       System.out.println("Total Property Values: " + totalValues);

       System.out.println("Total Property Taxes: " + totalTaxes);

       System.out.println("Average Property Tax" + average);

   }
