Java | Print root directories

Last Updated : 24 Mar, 2018

In Java we can use listRoots() of File class to find all root directories.

import java.io.*;

public class GeeksforGeeks {
    public static void main(String[] args)
    {
        File[] rDirs = File.listRoots();
        for (int i = 0; i < rDirs.length; i++) 
            System.out.println(rDirs[i].toString());        
    }
}

 
import java.io.*;
​public class GeeksforGeeks {    public static void main(String[] args)    {        File[] rDirs = File.listRoots();        for (int i = 0; i < rDirs.length; i++)             System.out.println(rDirs[i].toString());            }}
