java创建和删除文件夹、文件

实现代码如下：

//新建一个文件夹 public void newFolder(String folderPath) {     try {       String filePath = folderPath;       File myFilePath = new File(filePath);       if (!myFilePath.exists()) {         myFilePath.mkdir();       }     } catch (Exception e) {       System.out.println("新建文件夹操作出错");       e.printStackTrace();     }   } //删除文件夹 public void delFolder(String folderPath){     try{ String filePath = folderPath; File delPath = new File(filePath); delPath.delete();     }catch (Exception e) {       System.out.println("删除文件夹操作出错");       e.printStackTrace();     } } //新建文件 public void createFile(String fileName){     try{ String myFileName = fileName; if (!myFileName.exists()) {     myFileName.createNewFile(); }     }catch (Exception e) {       System.out.println("新建文件操作出错");       e.printStackTrace();     } } //删除文件 public void delFile(String fileName){     try{ String myFileName = fileName; myFileName.delete();     }catch (Exception e) {       System.out.println("删除文件操作出错");       e.printStackTrace();     } }
