         f = new File("test.txt");
         
         // set executable()
         bool = f.setExecutable(true, true);
         
         // prints
         System.out.println("setExecutable() succeeded?: "+bool);
         
         // can execute
         bool = f.canExecute();
         
         // prints
         System.out.print("Can execute?: "+bool);
