如何将一个循环中的增量更改为一个以上？

Question

For one of my programming projects, I was told to make one of these charts:

1 - 10  | *****
11 - 20 | **
21 - 30 | *******************
31 - 40 |
41 - 50 | ***
51 - 60 | ********
61 - 70 | **
71 - 80 | *****
81 - 90 | *******
91 - 100| *********

This is an array that when the user inputs numbers in a particular range it adds a * for each value entered in that range. I have already created a program that creates one of these charts. My next programming project tells me to only add an * for every five values entered in a particular range of numbers. If less than 5 values are entered then no * 's will be printed. I don't know how I should approach this problem.

Here is the code for the chart:

import java.util.Scanner;

public class SixFive
{
    public static void main(String[] args)
    {
        int[] counts = new int[10];

        Scanner scan = new Scanner(System.in);
        System.out.println("Enter integers between 1-100");

        while(scan.hasNextInt()) 
        {
            int num = scan.nextInt();
            if (num < 1 || num > 100) 
                break;
            counts[(num - 1) / 10]++;
        }

        scan.close();

        for (int i = 0; i < 10; i++) 
        {
            System.out.format("%2d -%3d ", i*10+1, i*10+10);
            for (int j = 0; j < counts[i]; j++)
                System.out.print("*");
            System.out.println();
        }
    }
}

In your inner loop, replace the condition j < counts[i] by j < counts[i] / 5 like this:

for (int i = 0; i < 10; i++) {
    System.out.format("%2d -%3d | ", i * 10 + 1, i * 10 + 10);
    for (int j = 0; j < counts[i] / 5; j++)
        System.out.print("*");
    System.out.println();
}
