Create folders and files in Java

// Author: [email] huapingsmith@hotmail.com [/Email]
// Description: Check whether the folder exists. If the folder does not exist, create one. If yes, continue running.
// After the folder is processed, the next step is to create a file in the folder.
// Caution: When a file named abc.txt already exists in the prefix folder,
// Creating a file named abc.txt in front of the folder will fail.
// In this program, if the file E: // test is named 1, 2, 3, and 4, the program will fail to be executed.
