Unit 2 OOAD

2–3 pages of Java code all Java filesAt this point, you are ready to start developing Java code to ask questions on customer information and the sub sandwichthat customers want to order. You are only concerned with the functionality to request and provide feedback on what the customer entered. Your main focus is on defining your classes and abstract classes and utilizing the concept of inheritance and polymorphism for the final sub the customer orders.

Also, be sure to comment all of your code to demonstrate that you understand what the code is doing.DeliverableThe following are the project deliverables: Update the title pageof the Design Document with the project name (Unit 2 IP) and the date. Add the following section header: “Phase 2 Application Screenshots.” Add screenshots of each distinct screen from your running application. Name the document “yourname_ITSD424_IP2.doc.” Submit the Design Document and zipped Java Project files for grading.19/05/202025informationsystems
