Yes. You know that you can put any Objectinto the Objectparameter of most JOptionPane.showXXX methods, and often that Objecthappens to be a JPanel.
是的。您知道可以将 anyObject放入Objectmost的参数中JOptionPane.showXXX methods，而且通常Object恰好是JPanel.
In your situation, perhaps you could use a JPanelthat has several JTextFieldsin it:
在您的情况下，也许您可以使用JPanel其中包含多个的a JTextFields：
import javax.swing.*;
public class JOptionPaneMultiInput {
public static void main(String[] args) {
JTextField xField = new JTextField(5);
JTextField yField = new JTextField(5);
JPanel myPanel = new JPanel();
myPanel.add(new JLabel("x:"));
myPanel.add(xField);
myPanel.add(Box.createHorizontalStrut(15)); // a spacer
myPanel.add(new JLabel("y:"));
myPanel.add(yField);
int result = JOptionPane.showConfirmDialog(null, myPanel,
"Please Enter X and Y Values", JOptionPane.OK_CANCEL_OPTION);
if (result == JOptionPane.OK_OPTION) {
System.out.println("x value: " + xField.getText());
System.out.println("y value: " + yField.getText());
}
}
}

this is my solution
这是我的解决方案
JTextField username = new JTextField();
JTextField password = new JPasswordField();
Object[] message = {
"Username:", username,
"Password:", password
};
int option = JOptionPane.showConfirmDialog(null, message, "Login", JOptionPane.OK_CANCEL_OPTION);
if (option == JOptionPane.OK_OPTION) {
if (username.getText().equals("h") && password.getText().equals("h")) {
System.out.println("Login successful");
} else {
System.out.println("login failed");
}
} else {
System.out.println("Login canceled");
}
