how to do all of this in java following the diagram in image 1 using these rules
Step by step
Solved in 3 steps
- java Create a Storage<T> abstract class. The class has abstract methods void print() which prints the object of the storage. The class has a non-abstract method add(T element) which adds the not-null element in the storage if the element is not already present. Create a class MyStorage which is a subclass of Storage.Below we have class diagrams with three classes for a simple java based parking management class. Use the classes below to write java code for classes :a parking observer class (that implements an observer pattern) , a transaction manager class and a parking lot class(subject to the observer). Use the class diagram and java class to implement it. You should use an observer pattern to implement your code.The main goal is to implement the following - Once a car enters (in an entry-scan only lot) or leaves (in an entry-scan and exit-scan lot), then the ParkingObserver will be updated, and then can register the charge with the parking system via the TransactionManager’s park() methodFor your application, explain the benefits of interfaces over abstract classes.

- Design a class named LinearEquation for a 2x2 system of linear equations: ax + by = ecx + dy = f x = (ed - bf)/(ad - bc ) y = (af - ec)/(ad-bc) The class contains:■ The private data fields a, b, c, d, e, and f with get methods.■ A constructor with the arguments for a, b, c, d, e, and f.■ Six get methods for a, b, c, d, e, and f.■ A method named isSolvable() that returns true if is not 0.■ The methods getX() and getY() that return the solution for the equation.Draw the UML diagram for the class, and then implement the class. Write a test program that prompts the user to enter a, b, c, d, e, and f and displays the result. If is 0, report that “The equation has no solution.”Part I: Implement the following classes Consider the following UML diagram for an application that manages spheres in the 3D space.
