Now, based on your design in Assignment $1($the picture I sent with the question$),$ try to realize these classes in Java. The following requirements should be fulfilled:

$1.$Abstract Class: Add at least one abstract class in your design to reflect theabstraction and inheritance relationships of object$-$oriented design.

$2.$Use of Object Class: Your classes should have the $$toString$($ and $$equals$()$methods$.$ Override the $$toString$($ method to return the string representation ofobjects, and override the $$equals$()$ method to compare the content of two objects forthe equality test.

$3.$Use of Collocation: Utilize Java collection classes, like ArrayList, to store andmanipulate data in your system.

$4.$ Use of Interfaces: Design and implement at least one interface to ensure codeflexibility and extensibility, Here, you can use Lambda Expression.

$5.$ Exception Handling: Include the necessary exception handling mechanisms in theprogram to ensure graceful handling of possible exceptions, thereby improving thestability and reliability of the program.

$6.$ Test Cases: Write adequate test cases to cover major functionalities and boundarycases to ensure the correctness and stability of the program. You can either add aseparate test class with a main method or add a main method in each class.Note:

Please be sure to follow the Java coding conventions, including naming conventions.

indentation, etc.
