Displaying and writing order line information (35 points) After entering a name, the program prints details for this order line in computer monitor. The information includes the five fields: customer name, customer phone number, pizza name (quantity), drink name (quantity), and a (formatted) total price, and each field is separated by simi colon and a space. A sample output to the monitor is as follows. Enter customer's name: John Smith Enter customer's phone number: 626-111-2222 Customer name: John Smith; Phone: 626-111-2222 Hawaiian Pizza Regular (1); Cheese Pizza Extra Large (1); Latte (1) Total: $26.50 Besides showing on monitor, the same order line content is written (appended) to a text file named pizzaorder.txt and each order line occupies three lines in the text file. Here is a specific example for an order in the pizzaorder.txt. Customer name: John Smith; Phone: 626-111-2222 Hawaiian Pizza Regular (1); Cheese Pizza Extra Large (1); Latte (1) Total: $26.50 Your program needs to create the output file, named pizzaorder.txt, if it doesn't exist yet, and later appends (not overwrite) order line information to the file. So next time when your program is executed, new order information will be appended to the pizzaorder.txt file. You must use a relative path when creating an output stream writer object. Design requirements: (20 points) You must have at least the following java classes. You may have additional classes if you want. [1] a PizzaOrder class to simulate the PizzaOrder entity in real world, which has fields of pizza, drinks, price of the order, customer name, customer phone number and corresponding methods. This class also provides a method to append the content of an order's content to the output text file, pizzaorder.txt. (PizzaOrder.java) [2] a java application, named OrderApp.java, that contains a main method. This class interacts with PizzaOrder class.
