Base on the diagram listed , write a java program shows ..abstract class and subclass inheritance (methods or fields ) ,

your program will have a technician where he say hello and welcome the customer then ask/suggest for the customer what next

(e.g. hello my name is smith the tech person lets build you computer , you will need ram and CPU and disk ...)

(customer say thank you , and at the end customer should have the enough money for pay (you don't need to make it like a POS just have the customer if he can or cant pay)

Note : *Make sure to have arrays of objects (or ArrayLists ) and demonstrate how you will override methods (you can use GUI if you prefer )
