Posted by: ranchgirl Posted on: 2005-08-11 11:34 Take a look at ANT Move task, it might help. I use it all the time, but have not looked at the Move source code. http://ant.apache.org |

Posted by: aleel_008 Posted on: 2005-08-27 15:33 I think the best way is to use the os invoke,such as the bat file. I could not image some case that we have to use the primitive api to move a file instead of to utilize the os invoke |

Posted by: q_yuan Posted on: 2005-09-06 09:28 我这儿有一个程序,你看一下。我这是把一个特定目录下的文件复制到自己选定的目录下,并且可以改文件名。 package test_Class; import java.awt.*; import java.awt.event.*; import java.io.*; import javax.swing.*; public class copy_File extends JFrame implements ActionListener{ private JButton bnt_send = new JButton("发送文件"); private FileDialog fd = new FileDialog(this,"另存为",FileDialog.SAVE); File file = new File("D:\\javaexe\\copy_File.java"); public copy_File(){ initCompoents(); setBounds(100,100,200,200); } public void initCompoents(){ setTitle("TEST"); bnt_send.setBounds(new Rectangle(50,50,100,20)); bnt_send.addActionListener(this); fd.setDirectory("E:\\"); fd.setFile("copy_File.java"); getContentPane().setLayout(null); getContentPane().add(bnt_send,null); addWindowListener(new WindowAdapter(){ public void windowClosing(WindowEvent evt){ setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }); } public void actionPerformed(ActionEvent evt){ FileInputStream fin = null; FileOutputStream fout = null; String s ,fileName; try{ fd.setVisible(true); fileName = fd.getDirectory()+fd.getFile(); fin = new FileInputStream(file); byte ss[] = new byte[fin.available()]; fin.read(ss); s = new String(ss); fout = new FileOutputStream(fileName); fout.write(s.getBytes()); }catch(Exception ex){} finally { try{ fout.close(); fin.close(); }catch(IOException ex){} } } public static void main(String[] arg){ new copy_File().show(); } } |
