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.
