Write a class name FileDisplay with the following methods:

• Constructor:  takes the name of a file as an argument


• displayHead:  displays only the first five lines of the file’s contents.  If the file contains less than 5 lines, it should display the file’s entire contents.


• displayContents:  displays the entire contents of the file, the name of which was passed to the constructor.


• writeNew:  displays the contents of a file, the name of which was passed to the constructor.  Each line should be preceded with a line number followed by a colon.  The line numbering should start at 1.  As each line is displayed it should also be written to a new file, the name of which is passed in as a parameter.

I have provided a test file called “testfile.txt”.  I have also provided a driver for the application called “filedisplaytest.java”.  This file is complete and should not be altered.

Test File:

This is line one.
This is line two.
This is line three.
This is line four.
This is line five.
This is line six.
This is line seven.

Extracted text: public class FileDisplayTest { public static void main (String [] args) throws IOException { // Create an instance of the FileDisplay object. FileDisplay fd = new FileDisplay("TestFile.txt"); // Test the displayHead method. System.out.println("File Head:"); fd.displayHeadlli // Test the displayContents method. System.out.println("\nFile Contents:"); fd.displayContents(); // Test the displayWithLineNumbers method. System.out.println("\nFile Contents with Line Numbers:"); //fd.displayWithLineNumbers(); fd.writeNew("TestFileNew.txt"); } }
