Question

我有两个独立运作的工作类。我想要将它们组合起来，但我没有工作地点来添加public void (String Name){。我一直在“删除此”或“添加}”。

我的代码：

import java.io.File;
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;

public class WordDocument extends JFrame {
private JButton btnOpen;
private JLabel jLabel1;
private JTextField txtDocNumber;
public void SystemFiles() {
private static String DIR  ="c:\\Users\\tyler's account\\folders\\JavaReaderFiles\\";   // folder where word documents are present.
public WordDocument() {
   super("Open Word Document");
   initComponents();
} 
private void initComponents() {
    jLabel1 = new JLabel();
    txtDocNumber = new JTextField();
    btnOpen = new JButton();

    Container c = getContentPane();
    c.setLayout(new java.awt.FlowLayout());
    setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

    jLabel1.setText("Enter Document Number  : ");
    c.add(jLabel1);

    txtDocNumber.setColumns(5);
    c.add(txtDocNumber);

    btnOpen.setText("Open Document");
    btnOpen.addActionListener(new ActionListener() {      // anonymous inner class 
        public void actionPerformed(ActionEvent evt) {
              Desktop desktop = Desktop.getDesktop();  
          try {
            File f = new File( DIR + txtDocNumber.getText()  +  ".doc");
             desktop.open(f);  // opens application (MSWord) associated with .doc file
          }
          catch(Exception ex) {
            // WordDocument.this is to refer to outer class's instance from inner class
            JOptionPane.showMessageDialog(WordDocument.this,ex.getMessage(),"Error", JOptionPane.ERROR_MESSAGE);
          }
        }
    });

    c.add(btnOpen);


}
public static void main(String args[]) {
      WordDocument wd = new WordDocument();
      wd.setSize(300,100);
      wd.setVisible(true);



                           }
}

我不知道在哪里添加方法。我尝试更改私有/公共类并不断收到多个错误。我需要它作为IF循环的一部分运行。

Answer 1

public void SystemFiles() {

看起来你启动了这种方法，但没有用}关闭它并且没有添加任何正文。

在Java中通过方法组合类
