试图弄清楚如何将用户从此 GUI 代码中选择的内容打印到另一个 GUI

Question

试图找出如何将用户从此 GUI 中选择的内容打印到另一个 GUI 上，并使其看起来像机票或收据。我很确定我可以设计机票 GUI。我在编写代码时遇到了问题，该代码将接受用户输入的任何内容并从下面的 GUI 代码中选择并将其打印到另一个 GUI。


import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.WindowConstants;

public class GUI implements ActionListener {

    private static JLabel firstNamelabel, lastNamelabel, fromLabel, toLabel, adultLabel, childrenLabel, bookingDate, LDate, classLabel, passengerDetails;
    private static JTextField firstNameuserText, lastNameuserText, bookingDateText;
    private static JComboBox fromCombo, toCombo, adultCombo, childrenCombo, classCombo;
    private static JButton button;

    public static void main(String[] args) {

        JPanel panel = new JPanel();
        JFrame frame = new JFrame();
        frame.setSize(400, 400);
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

        frame.add(panel);

        panel.setLayout(null);


        String[] sItem1 = { "New York" };
        String[] sItem2 = { "Florida ", "California ", "Texas ", "Chicago ", "Nevada ", "Ohio ", "Washington ","Georgia " };
        String[] sItem3 = { "Economic", "Business" };
        String[] item4 = { "1", "2", "3", "4", "5", "6" };
        String[] item5 = { "0", "1", "2", "3", "4" };

        passengerDetails = new JLabel("Passenger Details");
        passengerDetails.setBounds(10, 1, 150, 25);
        passengerDetails.setForeground(Color.blue);
        panel.add(passengerDetails);

        firstNamelabel = new JLabel("First Name");
        firstNamelabel.setBounds(10, 40, 80, 25); // x,y,width,height
        panel.add(firstNamelabel);

        firstNameuserText = new JTextField(20);
        firstNameuserText.setBounds(100, 40, 165, 25);
        panel.add(firstNameuserText);

        lastNamelabel = new JLabel("Last Name");
        lastNamelabel.setBounds(10, 65, 80, 25);
        panel.add(lastNamelabel);

        lastNameuserText = new JTextField(20);
        lastNameuserText.setBounds(100, 65, 165, 25);
        panel.add(lastNameuserText);

        fromLabel = new JLabel("From");
        fromLabel.setBounds(10, 110, 80, 25);
        panel.add(fromLabel);

        fromCombo = new JComboBox(sItem1);
        fromCombo.setBounds(50, 110, 125, 25);
        panel.add(fromCombo);

        toLabel = new JLabel("To");
        toLabel.setBounds(150, 110, 80, 25);
        panel.add(toLabel);

        toCombo = new JComboBox(sItem2);
        toCombo.setBounds(175, 110, 125, 25);
        panel.add(toCombo);

        adultLabel = new JLabel("Adult(12+)");
        adultLabel.setBounds(10, 150, 80, 25);
        panel.add(adultLabel);

        adultCombo = new JComboBox(item4);
        adultCombo.setBounds(10, 175, 80, 25);
        panel.add(adultCombo);

        childrenLabel = new JLabel("Children(2-11)");
        childrenLabel.setBounds(150, 150, 100, 25);
        panel.add(childrenLabel);

        childrenCombo = new JComboBox(item5);
        childrenCombo.setBounds(150, 175, 80, 25);
        panel.add(childrenCombo);

        bookingDate = new JLabel("Booking Date");
        bookingDate.setBounds(10, 225, 100, 25);
        panel.add(bookingDate);

        bookingDateText = new JTextField(20);
        bookingDateText.setBounds(100, 225, 140, 25);
        panel.add(bookingDateText);

        LDate = new JLabel("(MM/DD/YYYY)");
        LDate.setBounds(250, 225, 300, 25);
        LDate.setForeground(Color.red);
        panel.add(LDate);

        classLabel = new JLabel("Class");
        classLabel.setBounds(10, 275, 80, 25);
        panel.add(classLabel);

        classCombo = new JComboBox(sItem3);
        classCombo.setBounds(60, 275, 125, 25);
        panel.add(classCombo);

        button = new JButton("Make Reservation");
        button.setBounds(120, 325, 175, 25);
        button.addActionListener(new GUI());
        panel.add(button);

        panel.setBackground(Color.lightGray);

        frame.setVisible(true);

    }

    @Override
    public void actionPerformed(ActionEvent e) {
        String FirstName = firstNameuserText.getText();
        String LastName = lastNameuserText.getText();

    }

}

可能您应该首先创建一个 class 来保存从用户输入 (TicketRequest.class) 中获取的信息，并将包含数据的对象处理到新的 GUI。

代码思路：

 button.addActionListener(e -> {
            TicketRequest tr = new TicketRequest();
            tr.setName(firstNameuserText.getText());
            // ...
            GUInew guiNew = new GUInew(tr);
            guiNew.setVisible(true);
            
        
        });

GUInew class 可以扩展 JFrame。
