基于java的文件资源管理器

删除文件

	 public void deleteFile(File file) {
		 if(file!=null)
		    if (file.exists()) {//判断文件是否存在  
		     if (file.isFile()) {//判断是否是文件  
		      file.delete();//删除文件   
		     } else if (file.isDirectory()) {//否则如果它是一个目录  
		      File[] files = file.listFiles();//声明目录下所有的文件 files[];  
		      for (int i = 0;i < files.length;i ++) {//遍历目录下所有的文件  
		       this.deleteFile(files[i]);//把每个文件用这个方法进行迭代  
		      }  
		      file.delete();//删除文件夹  
		     }  
		    } else {  
		     System.out.println("所删除的文件不存在");  
		    }  
		   }  

复制文件

 public static void copy(File resFile, File objFolderFile) throws IOException { 
         if (!resFile.exists()) return; 
         if (!objFolderFile.exists()) objFolderFile.mkdirs(); 
         if (resFile.isFile()) { 
                 File objFile = new File(objFolderFile.getPath() + File.separator + resFile.getName()); 
                 //复制文件到目标地 
                 InputStream ins = new FileInputStream(resFile); 
                 FileOutputStream outs = new FileOutputStream(objFile); 
                 byte[] buffer = new byte[1024 * 512]; 
                 int length; 
                 while ((length = ins.read(buffer)) != -1) { 
                         outs.write(buffer, 0, length); 
                 } 
                 ins.close(); 
                 outs.flush(); 
                 outs.close(); 
         } else { 
                 String objFolder = objFolderFile.getPath() + File.separator + resFile.getName(); 
                 File _objFolderFile = new File(objFolder); 
                 _objFolderFile.mkdirs(); 
                 for (File sf : resFile.listFiles()) { 
                         copy(sf, new File(objFolder)); 
                 } 
         } 
	 }
