Progress Bar is not filling in properly

Question

I want to make a simulation hack program because I'm bored. I want it to fill a progress bar, here's the method for that:

public void HackFrame() {
    double count = 0;
    outerloop:
    for(char i = '!'; i <= '~'; i++){
        for(char j = '!'; j <= '~'; j++){
            for(char k = '!'; k <= '~'; k++){
                count++;
                int completion = (int) ((count / 830584) * 100);
                System.out.println(completion);
                HackCompletion.setValue((int) completion);
            }
        }
    }
}

Now I had System.out.println(completion) to make sure it would set values from 0 to 100. Which it does. The thing I don't understand is the progress bar. The only time it progresses is when I have System.out.println(completion);. Literally every time I remove that, the bar is always filled. Is there a reason I don't know?

Here's my entire code:

import java.awt.Color;
import javax.swing.*;
public class Hack {
    private String [] HackPhrases = {"Connecting to server. Sent control packet type is 7 (Outgoing-Call-Request)", "Validating user...", "Generating SHA-256 verification strings: 100%", "Validating blocks [1-512]: 512", "Connecting to game server. Outgoing call established (call ID 0, peer's call ID 19319)", "Establishing connection: 100%", "Connection successful on port 31337", "Downloading data: 100%", "Extracting data: 100%", "Calculating CRC values", "Packing data: 100%", "Injecting script. Sending 100%", "Checking server response...", "Generating Resources: 100%", "Generating Resources: Done", "Finalizing Process: 100%"};
    private JFrame Hack = new JFrame ();
    private JTextArea HackText = new JTextArea();
    private String Password = "~~~";
    private JProgressBar HackCompletion = new JProgressBar();
    public void makeFrame() {
        Hack.setSize(600, 400);
        Hack.getContentPane().setBackground(Color.black);
        HackText.setBounds(40, 20, 500, 200);
        HackText.setBackground(Color.black);
        HackCompletion.setBounds(140, 250, 300, 30);
        HackCompletion.setBackground(Color.green);
        HackCompletion.setForeground(Color.blue);
        Hack.add(HackCompletion);
        Hack.add(HackText);
        Hack.setLayout(null);
        Hack.setVisible(true);
        Hack.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
    public void HackFrame() {
        double count = 0;
        outerloop:
        for(char i = '!'; i <= '~'; i++){
            for(char j = '!'; j <= '~'; j++){
                for(char k = '!'; k <= '~'; k++){
                    count++;
                    int completion = (int) ((count / 830584) * 100);
                    System.out.println(completion);
                    HackCompletion.setValue(completion);
                }
            }
        }
    }
    public static void main (String [] args){
        Hack exampleHack = new Hack();
        exampleHack.makeFrame();
        exampleHack.HackFrame();
    }
}
