How do I run this code when holding "space" (Java)

Question

I made this program that spams space bar every 17 milliseconds and I am wanting it to only spam spacebar when I am holding space. Is there Any way I can do this? I tried watching some tutorials on it but could not figure it out. I am quite new to Java but I really just wanted to make this.

import java.awt.event.KeyEvent;
import javax.swing.*;
import java.awt.*;

public class skript {

    public static void main(String[] args) {
        boolean loop = true;
        while(loop = true) {
            try {
                Robot robot = new Robot();
                robot.keyPress(KeyEvent.VK_SPACE);
                robot.keyRelease(KeyEvent.VK_SPACE);           

                try { Thread.sleep(17); } 
                catch (InterruptedException e) { e.printStackTrace(); }

                robot.keyPress(KeyEvent.VK_SPACE);
                robot.keyRelease(KeyEvent.VK_SPACE);
            } 
            catch (AWTException e) { e.printStackTrace(); }
        }
    }
}
