在另一个类中使用带有逻辑的JavaSwingGUI
我想使用另一个类中的SwingGUI，在这个类中我的程序有逻辑。 逻辑类是下面代码中的类ApsVaje1。 例如，我有两个类GUI和Logic。在GUI中，我有JTextArea和JTextField以及一个JButton。在logic类中，我有一些方法可以执行一些操作，在logic类的main方法中，我非常喜欢
伪码
单击按钮时：
String text = GUI.JTextField.get text
String result = Method1(text)
JText Area.setText(result)
我的代码：
public class GUI extends javax.swing.JFrame {
/**
* Creates new form GUI
*/
public GUI() {
initComponents();
}
/**
* This method is called from within the constructor to initialize the form.
* WARNING: Do NOT modify this code. The content of this method is always
* regenerated by the Form Editor.
*/

我认为这个问题不清楚。 但据我所知， 只需在类ApsVaje1中创建GUI实例。之后，您可以在GUI上使用ApsVaje1的任何逻辑。可以删除GUI的主要方法
我希望它能解决你的问题。如果你认为我不理解这个问题，那么请再次澄清这个问题
