Java Example - Get the parent directory of a file

The following example demonstrates using the file.getParent() method of the File class to obtain the upper-level directory of the file:

/*
 author by w3cschool.cc
 Main.java
 */import java.io.File;public class Main {
   public static void main(String[] args) {
      File file = new File("C:/File/demo.txt");
      String strParentDirectory = file.getParent();
      System.out.println("文件的上级目录为 : " 
      + strParentDirectory);
   }}

The output result of running the above code is:

文件的上级目录为 : File

The above is the Java example - Get the contents of the upper-level directory of the file. For more related content, please pay attention to the PHP Chinese website (www.php.cn)!
