Hands on Command

Each student in our university has got 4 gold opportunities:

1. to go to academival leave

2. to return from academical leave

3. to pass exam

4. to fail the exam

Suppose we have a switch that regulates the leaving/returning, failing/pasing. The Command just an executor of this command - it changes states from "0" to "1" and in opposite.

Task

Create two classes that are responsible for (1) Academical leave and (2) Exam passing.

Each of these classes has exactly 2 methods: one for describing state "0" and another one for state "1".

• when the student goes to the academical leave, the console should display the meassage "Student left to the Academical leave";

• when the student returns from the academical leave, the console should display the meassage "Student returned from the Academical leave";

• when the student passes the exam, the console should display the message "Student succesfully passed the exam"

• when the student fails the exam, the console should display the message "Student failed and goes to retake"

Task

Implement Switch such that Command can be executed for state "0" (flipUp) or "1" (flipDown)

Task

Realise 4 classes for each of 4 states (passed, failed, acadevical leave, return from leave). Each class has constructor and a sigle execute method to change the state

Task

Test your implementation
