Java：showInputDialog中的自定义按钮

如何将自定义文本添加到JOptionPane.showInputDialog的按钮？

我知道这个问题JOptionPane showInputDialog与自定义按钮 ，但它没有回答问题，它只是将它们引用到JavaDocs，它没有回答它。

代码：
Object[] options1 = {"Try This Number", "Choose A Random Number", "Quit"};

 JOptionPane.showOptionDialog(null, "Enter a number between 0 and 10000", "Enter a Number", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE, null, options1, null); 

我想为此添加一个文本字段。

您可以使用自定义组件而不是字符串消息，例如：

 import javax.swing.JLabel; import javax.swing.JOptionPane; import javax.swing.JPanel; import javax.swing.JTextField; public class TestDialog { public static void main(String[] args) { Object[] options1 = { "Try This Number", "Choose A Random Number", "Quit" }; JPanel panel = new JPanel(); panel.add(new JLabel("Enter number between 0 and 1000")); JTextField textField = new JTextField(10); panel.add(textField); int result = JOptionPane.showOptionDialog(null, panel, "Enter a Number", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE, null, options1, null); if (result == JOptionPane.YES_OPTION){ JOptionPane.showMessageDialog(null, textField.getText()); } } }
