1、界面

一看到这个界面就这个窗体是一个空布局，界面其实很简单一个文本输入框、按钮和文本输入域

2、功能

按钮监听，一点击这个按钮就是列出所有该路径文件夹下的子文件

3、具体代码:

package FileSreach;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JScrollPane;import javax.swing.JTextArea;import javax.swing.JTextField;/** * 界面 * @author Administrator * */public class FileSreachFrame extends JFrame implements ActionListener{private static final long serialVersionUID = 1L;private JTextArea jta;private JTextField jtf;public static void main(String[] args){new FileSreachFrame().initSreachFrame();}private void initSreachFrame(){this.setSize(500,500);this.setTitle("文件搜索器");this.setLocationRelativeTo(null);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);this.setResizable(false);this.setLayout(null);jtf = new JTextField();jtf.setBounds(50,25,250,35);JButton button = new JButton("开始搜索");button.setBounds(350,25,100,35);button.addActionListener(this);jta = new JTextArea();JScrollPane jsp = new JScrollPane(jta);jsp.setBounds(50,125,400,300);this.add(jtf);this.add(button);this.add(jsp);this.setVisible(true);}@Overridepublic void actionPerformed(ActionEvent e) {if(e.getActionCommand().equals("开始搜索")){FileSreachFunction sreach = new FileSreachFunction(jtf,jta);//jta.removeAll();//FileSreachFrame.this.repaint();}}}

package FileSreach;import java.io.File;import javax.swing.JTextArea;import javax.swing.JTextField;/** * 实现 * @author Administrator * */public class FileSreachFunction {private JTextArea jta;public FileSreachFunction(JTextField jtf,JTextArea jta){this.jta = jta;this.initSreachFunction(jtf.getText());}private void initSreachFunction(String path){File file = new File(path);if(file.exists()&&file.length()!=0){if(file.isFile()){jta.append(file.getAbsolutePath()+"\r\n");}else{File[] files = file.listFiles();for (int i = 0; i < files.length; i++) {String absolute = files[i].getAbsolutePath();jta.append(absolute+"\r\n");this.initSreachFunction(absolute);}}}}}
