Given the following startup code of Java classes:

Listing 1: Task Class

Listing 2: TestingTask Class

1. Status Enumeration (4 marks) (a) Add a private constructor Status(int value) that initializes each constant to its value (2 marks)

(b) Add a getter method that retrieves the value of the read-only field value (2 marks)

2. Task Class (20 marks) (a) Add appropriate getters and/or setters for each instance variable (12 marks) A task cannot be set to a status whose value is less than or equal to its current status

(b) Add a constructor Task(String name) that i (4 marks) Setup a tasks Task(id)should be set to its hash code Setup the A tasks createdAt to the date when it was created

(c) Add a method toString() that returns a string representation of a task object in the format (see figure 1 on page 3) (4 marks) Figure 1: toString() Format

3. TestingTask Class (10 marks) (a) Add appropriate code in the main() method that displays the Status values in the following format (see figure 2 on page 3)

Figure 2: Enumeration Values

(b) Add appropriate code in the main() method that instantiates a task and modifies its status (see figure 3 on page 4) (6 marks)
