Directory Content:

Java allows you to get the names of all subdirectories and files in a folder as an array, which can then be sequentially viewed.

import java.io.*;
  
public class ListContents {
  public static void main(String[] args) {
    File file = new File("//home//user//Documents/");
    String[] files = file.list();
  
    System.out.println("Listing contents of " + file.getPath());
    for(int i=0 ; i < files.length ; i++)
    {
      System.out.println(files[i]);
    }
  }
}
