//在項目下建立一個名為hello的檔案夾
    public static void main(String[] args) {
        System.out.println(System.getProperty("user.dir"));
        createFolder("hello");
      }

     private static void createFolder(String folderName) {
       String temp = System.getProperty("user.dir") + java.io.File.separator+ folderName;
       java.io.File f = new java.io.File(temp);
       f.mkdirs();
     }

}

在Java程式中擷取當前運行程式的路徑

import java.io.*;

public class Test {

public static void main(String[] args) {

File directory = new File(".");

try {

File newPath = new File(directory.getCanonicalPath()+"NewFolder");

newPath.mkdir();

}catch(Exception exp)

{

exp.printStackTrace();

}

//File directory = new File(".");

//directory.getCanonicalPath();取得當前路徑
