package tsc;    import java.awt.GridLayout;  import java.awt.event.ActionEvent;  import java.awt.event.ActionListener;  import java.util.Timer;    import javax.swing.*;    import tsc.function.MyTask.myTask;    public class MyFrame extends JFrame{        private static final long serialVersionUID = 371204056893587903L;        public MyFrame() {          this.setTitle("文件移动工具");          this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);          this.setSize(300, 150);          this.setLocationRelativeTo(null);          this.setResizable(false);          this.setLayout(new GridLayout(1, 2));          JButton start = new JButton("移动");          JButton exit = new JButton("退出");JFrame frame1 = new JFrame("运行提示");JFrame frame2 = new JFrame("运行提示");            start.addActionListener(new ActionListener() {              public void actionPerformed(ActionEvent e) {                  File file = new File(Data.SOURCE);if(file.exists()){CopyFile.copyFile(Data.SOURCE,Data.PATH);frame1.setLocationRelativeTo(null);frame1.setSize(240, 150);frame1.setVisible(true);JLabel label = new JLabel("移动成功",JLabel.CENTER);label.setFont(new java.awt.Font("Dialog",0,15));JButton quit  = new JButton("确定");frame1.getContentPane().add("South",quit);frame1.getContentPane().add("Center",label);quit.addActionListener(new ActionListener(){public void actionPerformed(ActionEvent arg0){frame1.setVisible(false);}});}else{frame2.setLocationRelativeTo(null);frame2.setSize(240,150);frame2.setVisible(true);JLabel label = new JLabel("移动失败，未找到文件",JLabel.CENTER);label.setFont(new java.awt.Font("Dialog",0,15));JButton quit  = new JButton("确定");frame1.getContentPane().add("South",quit);frame1.getContentPane().add("Center",label);quit.addActionListener(new ActionListener(){public void actionPerformed(ActionEvent arg0){frame2.setVisible(false);}});}            }          });          exit.addActionListener(new ActionListener() {              public void actionPerformed(ActionEvent e) {                  System.exit(0);              }          });          getContentPane().add(start);          getContentPane().add(exit);      }  }

Data

package tsc;    public class Data {        //源文件所在绝对路径      public static final String SOURCE = "E:/ceshi/Source/source.bin";        //转移到的绝对路径      public static final String PATH = "E:/ceshi/Test/source.bin";

Main

package tsc;    import tsc.MyFrame;    public class Main {        public static void main(String[] args) {          new MyFrame().setVisible(true);      }    }
