Java Program to get the content of a directory
The contents of a directory can be obtained using the method java.io.File.listFiles(). This method requires no parameters and it returns the abstract path names that specify the files and directories in the required directory.
A program that demonstrates this is given as follows −
Example
import java.io.File; public class Demo { public static void main(String[] args) { File directory = new File("C:\JavaProgram"); File[] contents = directory.listFiles(); for (File c : contents) { if(c.isFile()) System.out.println(c + " is a file"); else if(c.isDirectory()) System.out.println(c + " is a directory"); } } }
The output of the above program is as follows −
Output
C:\JavaProgram\D is a directory C:\JavaProgram\Demo.class is a file C:\JavaProgram\Demo.java is a file C:\JavaProgram\Demo.txt is a file
Now let us understand the above program.
The method java.io.File.listFiles() is used to obtain the contents of the directory "C:\JavaProgram". Then these path names are displayed using the methods java.io.File.isFile() and java.io.File.isDirectory() that specify whether they are files or directories. A code snippet that demonstrates this is given as follows −
File directory = new File("C:\JavaProgram"); File[] contents = directory.listFiles(); for (File c : contents) { if(c.isFile()) System.out.println(c + " is a file"); else if(c.isDirectory()) System.out.println(c + " is a directory"); }
