java 创建文件夹 主要是程序红色部分
用 java 建立文件夹 package test; public class muluTest { public static void main(String[] args) { muluTest mulutest = new muluTest(); mulutest.newFolder("D:\\abcds"); } public { String filePath try { if(myFilePath.isDirectory()) { System.out.println("the directory is exists!"); } else { myFilePath.mkdir(); System.out.println("新建目录成功"); } } catch (Exception { System.out.println("新建目录操作出错"); e.printStackTrace(); } } } e) filePath = = folderPath; = new java.io.File(filePath); filePath.toString(); myFilePath void newFolder(String folderPath)
} } finally { if (is != null ) is.close(); } if } } result } return } public boolean delete(String path, MultipartFile file) throws Exception GXStringUtil gx = new GXStringUtil(); boolean result = false ; if (file != null && ! file.isEmpty()) { String fullPath = path + System.getProperty( " file.separator " ) + gx.netStringToGBK(file.getOriginalFilename()); try { File file2 = new File(fullPath); file2.delete(); result = true ; } catch (Exception e) { e.printStackTrace(); result = false ; } } return result; } public boolean deleteFolder(File folder) boolean result = false ; try { String childs[] = folder.list(); if (childs == null || { if (folder.delete()) { result = true ; } { } else { for ( int { { result; = true ; (out != out.close(); null ) { {
