Example:
Java
// Java Program to Check if Given File is Hidden or Not// Using isHidden() Method of File class// Importing required classesimport java.io.File;import java.io.IOException;// Main class// HiddenFileCheckpublic class GFG { // Main driver method public static void main(String[] args) throws IOException, SecurityException { // Creating a file by // creating an object of File class File file = new File( "/users/mayanksolanki/Desktop/demo.rtf"); // Checking whether file is hidden or not // using isHidden() method if (file.isHidden()) // Print statement as file is found hidden System.out.println( "The specified file is hidden"); else // Print statement as file is found as not // hidden System.out.println( "The specified file is not hidden"); }} |
Output:
Output Explanation: As it can easily be visualized from the background of the output that the ‘demo.rtf’ file popping icon is clearly seen. The code reflects that a specific file is not hidden on the terminal output as seen above.
Note: The precise definition of hidden is a platform or provider-dependent.
- UNIX: A file is hidden if its name begins with a period character (‘.’).
- Windows: A file is hidden if it is not a directory and the DOS hidden attribute is set.
