Question

Follow the UML diagram and directions on the attached file to create a RectangularPrism class and a RectangularPrismDemo class. --------------------------------------------------------------------------------------------------------------------------------------- RectangularPrism

Answer 1

thanks for the question, here are the two classes - RectangularPRism.java and RectangularPRismDemo.java with screenshot fo the output

======================================================================================

public class RectangularPrism {

    private double length;
    private double width;
    private double height;

    public RectangularPrism() {
        this.length = 0;
        this.width = 0;
        this.height = 0;
    }

    public RectangularPrism(double length, double width, double height) {
        this.length = length;
        this.width = width;
        this.height = height;
    }

    public void setLength(double length) {
        this.length = length;
    }

    public void setWidth(double width) {
        this.width = width;
    }

    public void setHeight(double height) {
        this.height = height;
    }

    public double getLength() {
        return length;
    }

    public double getWidth() {
        return width;
    }

    public double getHeight() {
        return height;
    }

    public double getVolume() {
        return getHeight() * getLength() * getWidth();
    }

    public double getSurfaceArea() {

        return 2 * (getWidth() * getLength() + getWidth() * getHeight() + getLength() * getHeight());
    }

    @Override
    public String toString() {
        return "Length: " + getLength() + ", Width: " + getWidth() + ", Height: " + getHeight() +
                ", Volume: " + getVolume() + ", Surface Area: " + getSurfaceArea();
    }
}

public class RectangularPrismDemo {

    public static void main(String[] args) {

        RectangularPrism prismOne = new RectangularPrism();
        RectangularPrism prismTwo = new RectangularPrism(6,4,10);
        prismOne.setLength(10);
        prismOne.setHeight(12);
        prismOne.setWidth(8);

        System.out.printf("Prism Two Height: "+prismTwo.getHeight());
        System.out.printf("\nPrism Two Length: "+prismTwo.getLength());
        System.out.printf("\nPrism Two Width: "+prismTwo.getWidth());

        System.out.printf("\nPrism One: "+prismOne);
        System.out.printf("\nPrism Two: "+prismTwo);
    }
}
