在Java中按下JButton时，在time.sleep完成之前返回boolean

Question

这是我的代码。如果用户按下按钮，我想返回true，否则返回false。我的问题是，当按下按钮时，它仍然等待time.sleep完成，然后返回。我该如何解决？

    public boolean popConfirmation(String action) {
        delete = false;
        JFrame frame = new JFrame();
        frame.setLayout(new BorderLayout());
        JPanel buttonPanel = new JPanel();
        buttonPanel.setLayout(new FlowLayout(FlowLayout.RIGHT));
        JButton clickmeButton = new JButton("Click Me");
        buttonPanel.add(clickmeButton);
        frame.add(buttonPanel,BorderLayout.SOUTH);

        frame.setSize(popUpWidth, popUpHeight);
        frame.setLocation(popUpX, popUpY);
        frame.setVisible(true);
        frame.setAlwaysOnTop(ALWAYS_ON_TOP);

        clickmeButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent arg0) {
                delete = true;
                frame.setVisible(false);
                frame.dispose();                    
            }           
        });

        try {
            Thread.sleep(20000);
        } catch (InterruptedException e) {
            logger.error("Error", e);
        }
        frame.setVisible(false);
        frame.dispose();

        return delete;
    }

Answer 1

尝试将Thread.interrupt（）放置在actionPerformed主体中。

Answer 2

我会尝试创建全局变量

私有线程线程；

然后使用thread.sleep（）和thread.interupt（）;
