Modify the CountByFives application so that the user enters the value to count by. Start each new line after 10 values have been

displayed.
public class CountByAnything
{
// Modify the code below
public static void main (String args[])
{
final int START = 5;
final int STOP = 500;
final int NUMBER_PER_LINE = 50;
for(int i = START; i <= STOP; i += START)
{
System.out.print(i + " ");
if(i % NUMBER_PER_LINE == 0)
System.out.println();
}
}

Answer:

The modified program is as follows:

import java.util.*;

public class CountByAnything{  

public static void main (String args[]){

   Scanner input = new Scanner(System.in);

final int START = 5;

final int STOP = 500;

int countBy; int count = 0;

System.out.print("Count By: ");

countBy = input.nextInt();

final int NUMBER_PER_LINE = 10;

for(int i = START; i <= STOP; i += countBy){

System.out.print(i + " ");

count++;

if(count == NUMBER_PER_LINE){

System.out.println();

count = 0;} } } }

Explanation:

To solve this, we introduce two variables

(1) countBy --> This gets the difference between each value (instead of constant 5, as it is in the program)

(2) count --> This counts the numbers displayed on each line

The explanation is as follows:

<em>final int START = 5; </em>

<em>final int STOP = 500;</em>

This declares countBy and count. count is also initialized to 0

int countBy; int count = 0;

This prompts the user for countBy

System.out.print("Count By: ");

This gets value for countBy

countBy = input.nextInt();

<em>final int NUMBER_PER_LINE = 10;</em>

This iterates through START to STOP with an increment of countBy in between two consecutive values

for(int i = START; i <= STOP; i += countBy){

This prints each number

System.out.print(i + " ");

This counts the numbers on each line

count++;

If the count is 10

if(count == NUMBER_PER_LINE){

This prints a new line

System.out.println();

And then set count to 0

count = 0;}

Westkost [7]

Answer:

The Java code is given below with appropriate variable names for better understanding

Explanation:

import java.util.Random;

import java.util.Scanner;

public class MultiplicationQuestions {

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       Random rand = new Random();

       int n1, n2, result, total = 0, correct = 0;

       char ch = 'y';

       while(ch == 'y'){

           n1 = 1 + rand.nextInt(9);

           n2 = 1 + rand.nextInt(9);

           System.out.print("What is "+n1+" * "+n2+" ? ");

           result = scan.nextInt();

           if(result==n1*n2){

               System.out.println("Correct. Nice work!");

               correct++;

           }

           else{

               System.out.println("Incorrect. The product is "+(n1*n2));

           }

           System.out.print("Want more questions y or n ? ");

           ch = scan.next().charAt(0);

           total++;

       }

       System.out.println("You scored "+correct+" out of "+total);

   }

}
