Idk my mouse wheel seems broken so I made this to test it

Mouse Tester

import javax.swing.*;

public class Tests{
	public static void main(String[] args){
		JFrame frame = new JFrame("mouse wheel test");
		frame.setBounds(30, 30, 300, 300);
		JLabel status = new JLabel("nothing");
		frame.add(status);
		status.setLocation(50, 50);
		frame.addMouseWheelListener(e -> {
			status.setText(e.getWheelRotation() == 1 ? "up" : "down");
			status.repaint();
		});
		frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
		frame.setVisible(true);
	}
}
