QUICK ANSWER

PLEASE READ EACH INSTRUCTION CAREFULLY & DON'T MISS ANYTHING AT ALL. THANKS!

It's a SEMESTER PROJECT, so the project idea should be in 40-50 words must be added in the start. An UML diagram, your code of all classes and screenshot of output MUST be pasted in the end as well. You have to implement all OOP concepts in your project specifically encapsulation, inheritance, polymorphism, abstraction and interfaces.

• IMPORTANT: Think about any management system, no need to develop an extensive system, you have to implement simple functionality. For reference, an example is given below but you must use another example such as Electricity billing system, Online quiz management system or Online bank management system. Just make sure it's easy to understand and thorough; YOU HAVE THE LIBERTY TO CHOOSE AN EASY TOPIC OF YOUR OWN CHOICE.
  • Online Food Order (Customer End)
    • First of all your program should display complete menu to user.
    • To place order, there should be complete list of food items with price.
    • In next step, customer will place order and provide his information for food delivery.
    • Complete order information should be saved in database.
    • In last step customer should be able to see his bill.
• First, you have to identify classes in your project and then instance variable and method for each classes. Carefully think about access modifiers of instance variable and methods.
• Once you have identified your classes, you have to make detailed UML class diagram. (PLEASE DEFINITELY ADD THIS)
• To read and write data you have to use database connectivity.
• No need to implement GUI.
• You program should handle all possible exceptions.

Please add screenshots of all outputs at the end and treat it as a semester project and make it as clear as possible, it holds a lot of % in our over-all grade; you're a great help for us.
