Write a Java class HmWk14. Create the method readTalkshow(list) in the HmWk14 class that that reads the file TALKSHOW.DAT. Each line in the data file will be stored into a Host Java class object and added to a list of Host objects. Make a note that the date in the file needs to be converted to a Date object before setting the birthday field in the Host class. Once the file has been read and saved into a list of Host objects, create another method displayTalkshow(list) which iterates the list and display the information for each talk show host. Create the class HmWk14 in the Java package edu.calhoun.cis.java.intro.homework.homework14. 2. Create the method writeTalkshow() to the Hmwk 14 class in Question #1 that that writes the Host objects to a new data file TALKSHOW_NEW.DAT. The birthday must be written in the format MM/DD/YYYY. Before writing the hosts to the new file, add a new Host object to the list by creating the method addHost(List hosts, String lastName, String firstName, String hostNumber, String birthday) and passing it the following values: Last Name: Meyers First Name: Seth Host Number: 0008 Birthday: 12/28/1973 Show the output generated by executing this program and show the contents of the newly created TALKSHOW NEW.DAT
