Question description

1. Write a complete Java GUI application that has input controls for input file name and output file name, an output control for number of rows processed, an output control for any error messages, and a read file and an exit button. 2. When the user clicks the read file button your application should read the specified input file, copy the contents to the specified output file, and count the number of rows processed to display, displaying any error messages as appropriate. 3. Organize the application as follows: a. A class with the main() method that will instantiate the UI screen class, invoke a method in that class to perform the processing, and set the screen to visible. b. A class that extends the JFrame class that provides the UI described above. c. A class that implements the ActionListener interface and invokes appropriate processing based on the button that was clicked (process file or exit the application). This class needs to determine the action, retrieve input controls, and convert them to appropriate data type. d. A class that actually reads the input text file and makes a copy to the specified output text file. This class should have instance variables for the input file name, the output file name, the number of rows processed and for an error message. In addition to the getter and setter methods associated with the instance variables it should have a method to perform the processing.
