重置切换按钮

Question

我正在为我的软件工程课程设计电梯。我正在使用面板内电梯轿厢上的切换按钮进行地板选择。如果当前楼层等于正在切换的按钮，我无法弄清楚如何关闭按钮。我已经包含了一个代码段。

package test;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.AbstractButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JToggleButton;
import javax.swing.SwingUtilities;

public class test {

public JPanel createContentPane() {

    // We create a bottom JPanel to place everything on.
    JPanel totalGUI = new JPanel();
    totalGUI.setLayout(null);

    // Creation of a Panel to contain the buttons
    JPanel buttonPanel = new JPanel();
    buttonPanel.setLayout(null);
    buttonPanel.setLocation(10, 80);
    buttonPanel.setSize(500, 500);
    totalGUI.add(buttonPanel);

    final JToggleButton floor3 = new JToggleButton("3");
    floor3.setSize(50, 50);
    floor3.setLocation(68, 100);
    buttonPanel.add(floor3);
    floor3.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            if (3 == 3) {
                AbstractButton abstractButton = (AbstractButton) e
                        .getSource();
                boolean selected = abstractButton.getModel().isSelected();
                System.out.println("Action - selected=" + selected + "\n");
                floor3.setSelected(!selected);
                // code to toggle the third floor button off
            }

        }
    });
    totalGUI.setOpaque(true);
    return totalGUI;
}

static void createAndShowGUI() {

    JFrame.setDefaultLookAndFeelDecorated(true);
    JFrame frame = new JFrame("Elevator");

    // Create and set up the content pane.
    test Welp = new test();
    frame.setContentPane(Welp.createContentPane());

    frame.setSize(250, 500);
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

public static void main(String[] args) {
    // Schedule a job for the event-dispatching thread:
    // creating and showing this application's GUI.
    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            createAndShowGUI();
        }
    });
}
}
