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;}
