How to work on File permissions ?

Check the file permissions

file.canExecute() // Checks if file is executable or not

file.canWrite()   // Checks if file is writable or not

file.canRead()    // Checks if file is readable or not

Set the file permission

file.setExecutable(boolean); // Sets execute permission and return true

file.setReadable(boolean); // Sets read permission and return true

file.setWritable(boolean); // Sets write permission and return true

Check if a file is hidden

File file = new File("c:/hidden-file.txt");

if(file.isHidden())

  System.out.println("This file is hidden");

else

  System.out.println("This file is not hidden");

Making file Read only and Read / Write

File file = new File("c:/MyFile.txt");

// Set the file as read only

file.setReadOnly();

if(file.canWrite())

  System.out.println("This file is writable");

else

  System.out.println("This file is read only");

// Set the file as writable

file.setWritable(true);

if(file.canWrite())

  System.out.println("This file is writable");

else

  System.out.println("This file is read only");
