In java 1.6 sun has introduced file handling API enhancement by which user can now set the readable, writable, and executable flag of a file in the local file system. This functionality has been added to the java.io.File class. The following are the methods added in the class.

Example Code:-

package visualbuilder;

import java.io.File;

public class Permission {

/**

* @param args

*/

public static void main(String[] args) {

    File file = new File("C:/a.txt");

    file.setExecutable(true);

    file.setReadable(true);

    file.setWritable(true);

    System.out.println("The Read permission "+ file.canRead());

    System.out.println("The Execute permission "+file.canExecute());

    System.out.println("The Write permission "+file.canWrite());

}

}

Output:- The following is the output of the above program.

The Read permission true

The Execute permission true

The Write permission true
