Question

我有这个程序在没有文件输入的情况下工作，我已经尝试过大量的谷歌搜索和询问，但无法弄明白。我不得不将firstnames和secondnames更改为ArrayList，任何想法如何解决这个问题？它也适用于已注释掉的文件的所有输入。

您的代码仍有一些问题。您需要学习的主要问题是EDT（必须从事件派发线程调用所有其他Swing组件方法）

您需要更新代码：

frame.setLocationRelativeTo(null);
frame.setResizable(true);
frame.setVisible(true);

在SwingUtilities中调用

SwingUtilities.invokeLater(() -> {
    frame.setLocationRelativeTo(null);
    frame.setResizable(true);
    frame.setVisible(true);
});

并改变：

    label.setText(result);
    label.setHorizontalAlignment(SwingConstants.CENTER);
    frame.add(label);

到

   SwingUtilities.invokeLater(() -> {
        label.setText(result);
        label.setHorizontalAlignment(SwingConstants.CENTER);
        frame.add(label);
        frame.revalidate();
        frame.repaint();
    });

ArrayList不使用文件输入
