Java Directory - Directory and File Listing Example in Java
This example illustrates how to list files and
folders present in the specified directory. This topic is related to the
I/O
(input/output) of java.io
package.
In this example we are using File class of java.io package. The File class is an abstract representation of file and directory pathnames. This class is an abstract, system-independent view of hierarchical pathnames. An abstract pathname has two components:
- An optional system-dependent prefix string,
such as a disk-drive specifier,"/"
for the UNIX root directory, or"\\"
for a Win32 UNC pathname, and - A sequence of zero or more string names.
Explanation
This program list the file of the specified directory. We will be declaring a function called dirlist which lists the contents present in the specified directory.
dirlist(String fname)
The function dirlist(String fname) takes directory name as parameter. The function creates a new File instance for the directory name passed as parameter
File dir = new File(fname);
and retrieves the list of all the files and folders present in the directory by calling list() method on it.
String[] chld = dir.list();
Then it prints the name of files and folders present in the directory.
Code of the Program :
import java.io.*;
