Good Evening Guys,

It was given an assignment in which I have to implement iava object oriented programing. What I'm saying is that I wrote a restaurant order program in java but the whole code is located in main. Now, they want me to implement diferent classes (super), constructors, accesors, mutators, methods, objects, inheritance, polymorfism, overloading, overring, interfaces, and exceptions. I already wrote my program which works perfectly, I do not know how to implement all this object oriented features in my existing code, the date line is coming up pretty soon. Please help!!!!!

This is my existing code:
