有没有办法在JOptionPane showInputDialog中仅具有OK按钮（而没有CANCEL按钮）？

只需将自定义JPanel添加为消息即可

JOptionPane.showOptionDialog()

String[] options = {"OK"};JPanel panel = new JPanel();JLabel lbl = new JLabel("Enter Your name: ");JTextField txt = new JTextField(10);panel.add(lbl);panel.add(txt);int selectedOption = JOptionPane.showOptionDialog(null, panel, "The Title", JOptionPane.NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, options , options[0]);if(selectedOption == 0){    String text = txt.getText();    // ...}
