Java移动文件

一：
//文件原地址
File oldFile = new File("c:/test.xls");
//文件新（目标）地址
String newPath = "c:/test/";
//new一个新文件夹
File fnewpath = new File(newPath);
//判断文件夹是否存在
if(!fnewpath.exists())
fnewpath.mkdirs();
//将文件移到新文件里
File fnew = new File(newPath +oldFile.getName());
oldFile.renameTo(fnew);

二：（使用ｊａｖａ复制移动文件 ）
   /**
      * Moving a File to Another Directory
      * @param srcFile  eg: c:\windows\abc.txt
      * @param destPath eg: c:\temp
      * @return success
      */
     public static boolean move(String srcFile, String destPath){
  // File (or directory) to be moved
  File file = new File(srcFile);
 
  // Destination directory
  File dir = new File(destPath);
 
  // Move file to new directory
  boolean success = file.renameTo(new File(dir, file.getName()));
 
  return success;
     }

三：(ｊａｖａ删除 移动文件)
File f=new File("c:\\Autoexec.bat");
f.renameTo("d:\\Autoexec.bat");//移动
f.delete();//删除

import ｊａｖａ.io.*;

public class MoveFile {
      public static void main(String[] args)throws IOException{
      File f=new File("d:\\myHomework\\Work");
      File fileList[]=f.listFiles();
      for(int i=0;i<fileList.length ;i++) {
   fileList[i].renameTo(new File("d:\\myHomework\\Backup\\" + fileList[i].getName()));
     }
}

四：ｊａｖａ操作文件(创建,删除,复制,剪切）

package OALogic.sql.data;
import ｊａｖａ.io.*;

public class FileOperate {
   public FileOperate() {
   }
  
   public static void main(String args[]){
       newFolder("D:/100");

   }

     * @return boolean
     */

       try {

           filePath = filePath.toString();
           ｊａｖａ.io.File myFilePath = new ｊａｖａ.io.File(filePath);
           if (!myFilePath.exists()) {
               myFilePath.mkdir();
           }
       }
       catch (Exception e) {
           System.out.println("新建目录操作出错");
           e.printStackTrace();
       }
   }

   /**

           }
           FileWriter resultFile = new FileWriter(myFilePath);

           String strContent = fileContent;
           myFile.println(strContent);
           resultFile.close();

       }
       catch (Exception e) {
           System.out.println("新建目录操作出错");
           e.printStackTrace();

       }

   }

   /**

     * @param fileContent String
     * @return boolean
     */
   public static void delFile(String filePathAndName) {
       try {

   }

           String filePath = folderPath;
           filePath = filePath.toString();
           ｊａｖａ.io.File myFilePath = new ｊａｖａ.io.File(filePath);
           myFilePath.delete(); //删除空文件夹

       }
       catch (Exception e) {
           System.out.println("删除文件夹操作出错");
           e.printStackTrace();

       }

   }

               delFolder(path+"/"+ tempList[i]);//再删除空文件夹
           }
       }
   }
