In this tutorial, i will teach you how to create a program in java that will check if a file is hidden or not. So, now let's start this tutorial! 1. Open Notepad. It's up to you if you will write data in there or not. Save it to the same folder with your java program and named it as READ FIRST.txt. and make sure to hide this file. 2. Open JCreator or NetBeans and make a java program with a file name of hiddenFile.java. 3. Import java.io package. Hence the file class is in the input/output library. Import also javax.swing package because we will use JOptionPane.showMessageDialog for displaying the output. 
  1. import java.io.*;
  2. import javax.swing.*;
4. In your main, initialize the READ FIRST.txt that you have created a while ago that has a file variable of File class. This will access this file inside the folder of your program. 
  1. File file = new File("READ FIRST.txt");
5. Now, create an if-else statement. In If statement, have the parameter of file.isHidden(). isHidden() method of the file class triggers to check if a file is hidden or not. By default, it is in True in nature as it is a Boolean data type. And it will prompt the user that the file is hidden. Then in Else statement, it will prompt the user that the file is not hidden. Note: READ FIRST.txt is hidden. 
  1. if (file.isHidden())
  2.         {
  3.            JOptionPane.showMessageDialog(null, "File is hidden!");
  4.         } else
  5.         {
  6.             JOptionPane.showMessageDialog(null, "File is not hidden!");
  7.         }
Press F5 to run the program. Output: output full source code: 
  1. import java.io.*;
  2. import javax.swing.*;
  3.  
  4. public class hiddenFile
  5. {
  6.     public static void main(String[] args) throws IOException
  7.     {
  8.         File file = new File("READ FIRST.txt");
  9.  
  10.         if (file.isHidden())
  11.         {
  12.            JOptionPane.showMessageDialog(null, "File is hidden!");
  13.         } else
  14.         {
  15.             JOptionPane.showMessageDialog(null, "File is not hidden!");
  16.         }
  17.     }
  18. }
