Java Example - View System Root Directory

The following example demonstrates using the listRoots() method of the File class to output all root directories of the system:

/*
 author by w3cschool.cc
 Main.java
 */

import java.io.*;

class Main{
   public static void main(String[] args){
      File[] roots = File.listRoots();
      System.out.println("系统所有根目录：");
      for (int i=0; i < roots.length; i++) {
         System.out.println(roots[i].toString());
      }
   }
}

The output result of running the above code is:

系统所有根目录：
C:\
D:\
E:\
F:\
G:\
H:\
