Java - File isHidden() method

The Java File isHidden() method checks whether the file named by this abstract pathname is a hidden file.

Following is the declaration for java.io.File.isHidden() method −

public boolean isHidden()

NA

The method returns true if and only if the file named by this abstract pathname is a hidden file else the method returns false.

• SecurityException − If a security manager exists and its SecurityManager.checkRead(java.lang.String) method denies read access to the file.

The following example shows the usage of Java File isHidden() method. We've created two File references. Then we're creating a File Object using test.txt which is not present in the current directory. Then we've created the file using createNewFile() method. Now using getAbsoluteFile() method, we're getting the file and checking the file status as hidden using isHidden() method and printing it.

package com.tutorialspoint;
import java.io.File;
public class FileDemo {
   public static void main(String[] args) {      
      File f = null;
      File f1 = null;
      
      try {
         // create new files
         f = new File("test.txt");
         
         // create new file in the system
         f.createNewFile();
         
         // create new file object from the absolute path
         f1 = f.getAbsoluteFile();
         
         // prints the file status
         System.out.print("Is file hidden: "+ f1.isHidden());
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Let us compile and run the above program, this will produce the following result−

Is file hidden: false

The following example shows the usage of Java File isHidden() method. We've created a File reference. Then we're creating a File Object using F:/test.txt which is present in the provided directory. Now using getAbsoluteFile() method, we're getting the file and printing file status as hidden using isHidden() method.

package com.tutorialspoint;

import java.io.File;

public class FileDemo {
   public static void main(String[] args) {      
      File f = null;
      
      try {
         // create new files
         f = new File("F:/test.txt");         
    
         // get the file
         File f1 = f.getAbsoluteFile();
         
         // prints the file is hidden or not
         System.out.println("Is file hidden: "+f1.isHidden());
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Let us compile and run the above program, this will produce the following result −

Is file hidden: true

The following example shows the usage of Java File isHidden() method. We've created a File reference. Then we're creating a File Object using F:/test directory which is present in the provided location. Now using getAbsoluteFile() method, we're getting the directory and its hidden status using isHidden() method.

package com.tutorialspoint;

import java.io.File;

public class FileDemo {
   public static void main(String[] args) {      
      File f = null;
      
      try {
         // create new files
         f = new File("F:/test");         
    
         // get the file
         File f1 = f.getAbsoluteFile();
         
         // prints the file as hidden or not
         System.out.println("Is file hidden: "+f1.isHidden());
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Let us compile and run the above program, this will produce the following result −

Is file hidden: false
