任何人都可以建议我如何将我的GUI连接到我的基类 我已经编写了gui并设计了它，但是现在需要GUI来与我制作的另一个类进行交互。
编辑：在我的线程中添加了更新的代码，添加了新的方法，在按下按钮时将文本打印到TextFields。即显示约会，显示按钮旁边文本字段中的所有约会。 此外，需要尝试为用户添加一个选项，以使用公历日历格式
输入自己的约会 package com.appointmentsys;

您已拥有大部分代码。您在ControllerGUI中有一个AppointmentBook类的实例
AppointmentBook appBook = new AppointmentBook();
您可以在事件处理程序中使用该appBook对象。
public class EventHandler implements ActionListener{
public void actionPerformed(ActionEvent e){
if(e.getSource() == button1) {
appBook.add(new Appointment());
}
}
}
我没有在那里看到Appointment类的代码，但你可以在appBook.add调用中调用Appointment类的构造函数。
E.g。
appBook.add(new Appointment("21-01-2016", "Meeting"));
如果你有一个构造函数，它接受2个字符串进行约会
编辑：
看到你的附加代码后，我发现你有2个main（）方法。所以这些是真正的2个独立的程序。
您可以尝试将两种主要方法结合起来。
而不是在main方法中进行一堆约会。您应该通过单击其中一个按钮来测试添加约会。
public class EventHandler实现ActionListener {
public void actionPerformed(ActionEvent e){
if(e.getSource() == button1) {
appBook.add(new Appointment(new GregorianCalendar(2015, 8+1, 14, 10, 30 ), new GregorianCalendar(2015, 10, 14, 11, 30), "Danny"));
}
}
}
您还可以选择另一个按钮来调用appBook.ShowAppointments（）方法。
添加像这样的编码约会并不理想。所以测试一下然后添加一些允许你传入值的方法。
您根本不需要其他主要方法来实现此功能，只需使用CreateandShowGUI调用。
EDIT2：
您的Appointment类中已经有一个toString方法。
在您的AppointmentBook类中添加一个getAppointment方法，该方法允许您通过索引获取任何约会，并将该索引作为参数。会返回appointmentList.get(index);
因此，在您的eventHandler中，您可以使用它来设置文本字段。
public void actionPerformed(ActionEvent e){
if(e.getSource() == button3) {
String appointmentInfo = appBook.getAppointment(0).toString();
ta.setText(appointmentInfo);
}
}
这假设您的appBook对象中至少有一个约会。因此，在尝试设置文本之前，您必须添加一些代码来检查appBook是否为空。
EDIT3：
您实际上并未使用EventHandler。这是您的ControllerGUI文件应该是这样的：
public class ControllerGUI extends JPanel {
static JButton button1;
static JButton button2;
static JButton button3;
static JButton button4;
static JTextField ta;
static AppointmentBook appBook = new AppointmentBook();
static EventHandler eventHandler;
public static void CreateandShowGUI() {
JFrame frame = new JFrame();
JPanel panel = new JPanel();
panel.setLayout(new GridLayout(10, 10));
button1 = new JButton("Add appointment");
button2 = new JButton("Remove appointment");
button3 = new JButton("Show appointment");
ta = new JTextField();
button4 = new JButton("Search appointments");
eventHandler = new EventHandler();
button1.addActionListener(eventHandler);
button2.addActionListener(eventHandler);
button3.addActionListener(eventHandler);
button4.addActionListener(eventHandler);
frame.setContentPane(panel);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
panel.add(new JLabel(" "));
panel.add(new JLabel("Please select an option: "));
panel.add(new JLabel(" "));
panel.add(button1);
panel.add(button2);
panel.add(button3);
panel.add(button4);
panel.add(ta);
panel.setBorder(BorderFactory.createTitledBorder("Appointment System"));
}
public static class EventHandler implements ActionListener {
public void actionPerformed(ActionEvent e) {
if (e.getSource() == button1) {
appBook.add(new Appointment(new GregorianCalendar(2015, 8 + 1, 14, 10, 30), new GregorianCalendar(2015, 10, 14, 11, 30),
"Danny"));
}
if (e.getSource() == button3) {
ta.setText(appBook.getAppointment(0).toString());
}
}
}
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
CreateandShowGUI();
}
});
}
}
AppointmentBook类中的方法应如下所示：
public Appointment getAppointment(int index) {
return appointmentList.get(0);
}
我真的建议你在继续之前修改很多基础知识。您需要更好地掌握方法（传递参数和返回值）。在尝试此级别的GUI程序之前，您需要完成所有这些工作。
在上面的类中，我将EventHandler类设为静态，然后在CreateandShowGUI类中创建了它的实例。然后我将按钮添加到EventHandler（actionlistener）。这刚刚重新调整了您的代码。最好有一个类在一个单独的文件中处理所有这些，这不是一个静态类。因此，您可以实例化它并对所需的方法进行任何和所有调用，而不需要它们是静态的。
这是我现在能给予的所有帮助。

您应该使用MVC开发方法，
您的业务逻辑位于Gui可以调用的服务的底部，然后您可以将网站/ swing /任何其他视图系统放在顶部 或多或少地将API访问到您的业务逻辑中
AppointmentService.addAppointment（约会约会）; AppointmentService.getAppointments（）;
等
答案 2 :(得分：0)
从简单的命令行界面（CLI）类开始。
只需使用main()方法编写一个练习AppointmentBook的类。
一旦了解了AppointmentBook的工作原理，请返回GUI。
