Question

Program 1 Write an inheritance hierarchy of three-dimensional shapes. Make a top-level shape interface that has methods for getting information such as the volume and the surface area of a three-dimensional shape. Then make classes and subclasses that implement various shapes such as cube, cylinders and spheres. Place common behavior in superclasses whenever possible, and use abstract classes as appropriate. Add methods to the subclasses to represent the unique behavior of each three-dimensional shape, such as a method to get a sphere's radius. Select three shapes from the list: sphere, cube, tetrahedron, cone, cylinder and rectangular prisms. On BlackBoard post the following items: • Description of the lab in your own words. Source Code with comments • UML Diagram for each Class • Screenshots of you program running and results. Program 2 Write a Java program that creates a string arraylist and then adds 10 grocery items to the list. Then, it prompts the user to enter another item, it searches the list, if it is not found, it adds it to the list, otherwise it displays a message that the item is already in the list. At the end display the list. In BlackBoard post the following information: • Comments with your name, date and description of the program Screenshots of you program running. Source Code.

THIS IS IN THE JAVA SCRIPT CODE

ALSO PLEASE SEND ME THE CODE TYPED THANK YOU.

Answer 1

Methods.java

public interface Methods {

   double getArea();
   double getVolume();
}

Shape.java

public abstract class Shape implements Methods {

   int param;

   public Shape(int param) {
       super();
       this.param = param;
   }

   public int getParam() {
       return param;
   }

   public void setParam(int param) {
       this.param = param;
   }

   @Override
   public String toString() {
       return "Shape [Dimension=" + param + "]";
   }
  
  
  

Sphere.java

public class Sphere extends Shape{

   public Sphere(int param) {
       super(param);
       // TODO Auto-generated constructor stub
   }

   @Override
   public double getArea() {
       // TODO Auto-generated method stub
       return 4*Math.PI*Math.pow(this.param,2);
   }

   @Override
   public double getVolume() {
       // TODO Auto-generated method stub
       return 4*Math.PI*Math.pow(this.param,3)/3;
   }
  
   @Override
   public String toString() {
       return "Sphere [Radius: " + param + ", Area: "+this.getArea()+", Volume: "+this.getVolume()+"]";
   }

}

Cylinder.java

public class Cylinder extends Shape {
  
   int height;

   public Cylinder(int radius,int height) {
       super(radius);
       // TODO Auto-generated constructor stub
       this.height = height;
   }

   @Override
   public double getArea() {
       // TODO Auto-generated method stub
       return 2*Math.PI*this.param*(this.param+this.height);
   }

   @Override
   public double getVolume() {
       // TODO Auto-generated method stub
       return Math.PI*Math.pow(this.param, 2)*this.height;
   }
  
   @Override
   public String toString() {
       return "Cylinder [Radius: " + param + ", Height: "+this.height+", Area: "+this.getArea()+", Volume: "+this.getVolume()+"]";
   }

}

Cube.java

public class Cube extends Shape{

   public Cube(int param) {
       super(param);
       // TODO Auto-generated constructor stub
   }

   @Override
   public double getArea() {
       // TODO Auto-generated method stub
       return 6*Math.pow(this.param,2);
   }

  
   public double getVolume() {
       // TODO Auto-generated method stub
       return Math.pow(this.param,3);
   }
  
   @Override
   public String toString() {
       return "Cube [Edge: " + param + ", Area: "+this.getArea()+", Volume: "+this.getVolume()+"]";
   }

}

ShapeTester.java

public class ShapeTester {

   public static void main(String[] args) {
       // TODO Auto-generated method stub

       Shape[] shapes = new Shape[3];
      
       shapes[0] = new Sphere(5);
       shapes[1] = new Cube(5);
       shapes[2] = new Cylinder(5,3);
      
       for(Shape s : shapes)
           System.out.println(s);
   }

}

Output

Sphere [Radius: 5, Area: 314.1592653589793, Volume: 523.5987755982989]
Cube [Edge: 5, Area: 150.0, Volume: 125.0]
Cylinder [Radius: 5, Height: 3, Area: 251.32741228718345, Volume: 235.61944901923448]
