X444: Polymorphism Practice 3

For this question assume the following implementations of Computer, Tablet, and Notebook

public class Computer {
    private String manufacturer;
    private String processor;
    private int ramSize;
    private int diskSize;
    private double processorSpeed;

    public Computer(String man, String pro, int raSize, int diSize, double proSpeed) {
        manufacturer = man;
        processor = pro;
        ramSize = raSize;
        diskSize = diSize;
        processorSpeed = proSpeed;
    }


    public String getManufacturer() {
        return manufacturer;
    }


    public int getRamSize() {
        return ramSize;
    }


    public int getDiskSize() {
        return diskSize;
    }


    public double getProcessorSpeed() {
        return processorSpeed;
    }


    public String toString() {
        return "My Computer is: \n Manufacturer: " + manufacturer
            + "\n CPU: " + processor + "\n RAM: " + ramSize
            + " gigabytes\n Disk: " + diskSize + " gigabytes\n Speed: "
            + processorSpeed + " gigahertz";
    }

}

public class Tablet extends Computer{
    private int length;
    private int width;
    private String operatingSystem;

    public Tablet(String man, String pro, int raSize, int diSize, double proSpeed, int len, int wid, String os) {
        super(man, pro, raSize, diSize, proSpeed);
        length = len;
        width = wid;
        operatingSystem = os;
    }

    public int getArea() {
        return length * width;
    }

    @Override
    public String toString() {
        return "My Tablet was made by: " + getManufacturer()
            + ", and has a screen area of: " + getArea();
    }

}

public class Notebook extends Computer{
    public Notebook(String man, String pro, int raSize, int diSize, double proSpeed) {
        super(man, pro, raSize, diSize, proSpeed);
    }
}

Write a method that takes in a variable comp of type Computer. If comp is a Tablet, return the area. Otherwise, return the disk size of the computer.
