Question
Please use Java to finish this program, thanks!
Exercise 3: Suppose that you want to store student records in the generic stack that you created in Exercise 2. For this, first define a StudentRecord class that holds three attributes: String firstName, String lastName, int bannerID. Add the appropriate constructor, get, set and toString methods. Next, write a client (demo) program that does the following 1. Create an empty stack, stackl, that can hold student records 2. Read a file that contains student records, one on each line, such as Ichabod Crane 123456 Brom Bones 456321 Emboar Pokemon 111222 Rayquazza Pokemon 333111 Cool Dude 101010 Trend Chaser 654321 Chuck Norris 112233 Drum Dude 111222 You may assume that each line has three components only: first name, last name and Id number. You would read the ID number as a String and then convert it to an Integer object A StringTokenizer program is useful to read a file in which the records are arranged as shown above and split them into first name, last name and ID number 3. As each line in the file is read, create a StudentRecord object and push it into stackl 4. Repeat until all the lines in the file are read 5. Create another stack2 that can hold string objects 6. Pop stackl item by item and push only the last name in each student record into stack2 7. Pop stack2 and display the items. With the example set of records given above, this would display the last names in the reverse order: Dude Norris ChaserExplanation / Answer
