CODE IN JAVA 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. FILEDISPLAYTEST.JAVA (do not change this) import java.io.*; public class FileDisplayTest { publicstaticvoidmain(String[] args) throwsIOException { // Create an instance of the FileDisplay object. FileDisplayfd = newFileDisplay("TestFile.txt"); // Test the displayHead method. System.out.println("File Head:"); fd.displayHead(); // Test the displayContents method.
