- Refactor the ConsoleUl class to make it more reusable and testable. This can be achieved by separating the input and output streams from the business logic. Consider passing in input and output streams as arguments to the constructor. - Write a JUnit test class named ConsoleUITest to test every public method, including the constructors. - In ConsoleUITest, use a ByteArraylnputStream to simulate user input and a ByteArrayOutputStream to capture the output from ConsoleUI. This will enable us to test ConsoleUl in isolation without relying on the actual console input and output
