Thread: Number Counting Array issues

My assignment is this:
Design and implement an application that reads a set of values in the range 1 to 100 from the user and then creates a chart showing how often the values appeared.
This is my code so far:

import java.util.*;
public class chap6pp4 { //this is just the assignment number in my textbook-- chapter 6 programming project 4
 
    public static void main() 
    {
        int numbers[] = new int[10];
        int appearNum;
 
        Scanner scan = new Scanner (System.in);
 
        System.out.println("Enter a set of values from 1 to 100: ");
        appearNum = scan.nextInt();
 
        while (appearNum >= 1 && appearNum <= 100)
        {
            numbers[(appearNum--) / 10]++;
 
            System.out.println("Enter another number (-1 to quit): ");
            appearNum = scan.nextInt();
        }
 
        System.out.println();
 
        for (int i = 0; i < numbers.length; i++)
        {
            System.out.print ("   " + (i*11) + " - " + (i+1)*10 + "\t| ");
 
            for (int j = 0; j < numbers.length; j++) 
 
            {
 
                System.out.print ("*");
 
            }
 
 
            System.out.println (); 
 
        } 
 
    }
 
}

So it compiles, but when I try to run the code by putting some numbers in it keeps on asking me to put more numbers in, or press -1 to quit. When I do -1, it shows a full asterisk chart.
This is what it looks like :
Enter a set of values from 1 to 100:
1 2 4 64 33 33 52 74 74 2 44
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
2 2 44 33 33
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
Enter another number (-1 to quit):
-1

0 - 10 | **********
11 - 20 | **********
22 - 30 | **********
33 - 40 | **********
44 - 50 | **********
55 - 60 | **********
66 - 70 | **********
77 - 80 | **********
88 - 90 | **********
99 - 100 | **********

those inputted numbers are mine. This is what I want the chart to look like, but the program isn't running the way it is supposed to and I don't know why.
Any help is much appreciated!

You're on the right track but need to give it a bit more thought. You should ask yourself, "Is the program written to accept a bunch of numbers entered on a single line?", and "Why are 10 stars printed for every value?" The answers to these questions are fairly simple and obvious and should point you to logic corrections.

thanks. i went through again after posting and realized a couple dumb things i did wrong, I'm just having issues with printing things for specific answers within a group.

I'm just having issues with printing things for specific answers within a group.

Can you explain what this means? It sounds like you're talking about a different problem entirely. "Printing things," (what things?), "specific answers," (what answers to what questions?, and "within a group" (what group?) don't make much sense. I can almost connect "group" to the frequency range you're collecting, but I'm not sure that's right. Don't talk in riddles.

i was dismissing my issue as one based in dumb things that i didn't do. i meant that i was having issues printing the asterisk for each set of 10 answers within each individual set without making a different section for each 10.
hardly a riddle.
