Question
Create a class named Organ with the following private instance and class fields: [ 0.5 Pt ] serial ( int ) : Cannot be negative
Create a class named Organ with the following private instance and class fields: [0.5 Pt]
- serial (int) : Cannot be negative
- type (String) : Cannot be null
- density (double) : Cannot be negative
- total (int) to keep track of the total number of Organ objects created.
2. Provide a full-argument constructor [1 Pt]
Important Note 2: Make sure to validate the input arguments.
3. Provide a no-argument constructor [0.25 Pt]
Important Note 3: Make sure to call the full-argument constructor
4. Provide a copy constructor [0.5 Pt]
Important Note 4: Make sure that the input argument is not null by calling Objects.requireNonNull() method
5. Provide setter and getter methods [1 Pt]
Important Note 5: Make sure to validate the input arguments of each setter method.
6. Override the toString() to return the String representation of the current object [1 Pt]
Important Note 6: The String representation looks like:
Organ(123, Upper Body, 13.445, 234)
when serial = 123, type = Upper Body, serial = 13.445, and there are 234 Organ objects created. Floating-point numbers are formatted using 3 decimals.
Part II:
1. Create a class named DonatedOrgan that extends the Organ class. The DonatedOrgan class defines two private fields: [0.5 Pt]
- donor_age (int) : Cannot be negative
- donor_name (String) : Cannot be null
2. Provide a full-argument constructor [1 Pt]
Important Note 1: Make sure to validate the input arguments.
3. Provide setter and getter methods [1 Pt]
Important Note 2: Make sure to validate the input arguments of each setter method.
4. Override the toString() to return the String representation of the current object. Your implementation must call the toString() method of the Organ class [1 Pt]
Important Note 4: The String representation looks like:
DonatedOrgan(123, Upper Body, 13.445, 234, 25, Ahmed)
when serial = 123, type = Upper Body, serial = 13.445, age = 25, name = Ahmed, and there are 234 DonatedOrgan objects created. Floating-point numbers are formatted using 3 decimals.
