Question

Showy Shiny Shoe Store The Showy Shiny Shoe Store sells different styles of shoes, such as sandals and walking shoes. Each style of shoe is offered in different colors, such as brown and black. Available shoe sizes range from size 5 to size 11, in both whole and half sizes. Design an object-oriented computer program by doing the following: Create a class diagram (a UML diagram) for the Shoes class that contains the style of the shoes, the color of the shoes, and the size. Examples of valid values for the style are "sandals" and "walking". Examples of valid values for the color are "brown" and "black". Examples of valid values for the size are 6.5 and 9.0. Be sure to choose the most appropriate data type for the attributes. For this class definition, include the following: A default constructor that initializes each attribute to some reasonable default value for non-existent shoes. Another constructor method that has a parameter for each data member. This constructor initializes each attribute to the value provided when an object of this type is instantiated. Accessor and mutator methods for each attribute. A method that displays all the data about the shoes. Note, if you are using ArgoUML for the diagram, make sure you use the template. First, download the template, then resave it with a different file name. The template can be found on the main page of this module. For your convenience, you may download it here. ClassDiagramTemplate.zargo Also note, ArgoUML does not have undo feature, please save often. Add a class diagram (a UML diagram) for the application (the one with a main function) to the one you created for the part The application program for the shoe store with a main() module will instantiate two objects of the Shoes class. The first object should be named nerdShoes and use the default constructor. The second object should be named coolShoes and use the second constructor to initialize the style to "sandals", the color to "brown", and the size to 8.5. Include the following instructions in the main() method, in the order specified below: A call to set the color of the nerdShoes to "tan". A call to set the style of the nerdShoes to “walking”. A call to set the size of the nerdShoes to 9.5. A statement that displays the style of the nerdShoes, using the appropriate method call. A call to change the color of the coolShoes to "purple". A statement that displays the style of the coolShoes, using the appropriate method call. A call for the coolShoes object to the method that displays all the information about the shoes Write the pseudocode or Java programs base on the UML diagrams you created above. You need to write two programs - a class program and an application program. If you are using Java, do not submit the bytecode - in .class format. Files and file formats: The UML diagram (due the Friday of the first week) file format: .zargo, .docx, .jpg, .png The Class program either pseudocode or Java (due the Friday of the second week) file format: .zip The application program either pseudocode or Java (due the Friday of the second week) file format: .zip

Answer 1

Dear Student,

I have created shoes class and Driver class.

Shoe class has attributes, it is a class program as per your convention

driver class is an application program. I have written code provided adequate comments for your understanding.

I have created a UML diagram in eclipse, as the question indicates that we may use any tool for generating UML.

In eclipse editor, you can install ObjectAid UML explorer. You can select the java files and generate UML diagram. I am pasting the code, output and UML diagram below. Please refer them,

I have developed a code for all the requirements.

Please use any editor for testing the code

Let me know if you find any difficulties in understanding.

package wearable;

//shoes class which has all attributes and logic
public class Shoes {

   //attributes
   private String style;
   private String color;
   private double size;

   //Default constructor
   public Shoes() {
       this.style = "No Style";//default values
       this.color = "No Color";
       this.size = 0;
   }
   //constructor with paramaters
   public Shoes(String style, String color, double size) {
       this.style = style;
       this.color = color;
       this.size = size;
   }

   @Override// to print data of the object
   public String toString() {
       return "Shoe Details: [style=" + style + ", color=" + color + ", size=" + size + "]";
   }
  
   //Accessor and mutator methods for all attribute
   public String getStyle() {
       return style;
   }

   public void setStyle(String style) {
       this.style = style;
   }

   public String getColor() {
       return color;
   }

   public void setColor(String color) {
       this.color = color;
   }

   public double getSize() {
       return size;
   }

   public void setSize(double size) {
       this.size = size;
   }

}

package wearable;
//application program as mentioned in the question. This is for manipulating and using shoes objects
public class Driver {

   public static void main(String[] args) {
       //creation of objects
       Shoes nerdShoes=new Shoes();
      
       Shoes coolShoes =new Shoes("sandals","brown",8.5);

       //setting values for nerdShoes object
       nerdShoes.setColor("tan");
       nerdShoes.setStyle("walking");
       nerdShoes.setSize(9.5);
       System.out.println("nerd shoes style: "+nerdShoes.getStyle());
      
       coolShoes.setColor("purple");
       System.out.println("cool shoes style: "+coolShoes.getStyle());
      
       //this will call toString method in the shoes class. Print coolShoes object details
       System.out.println(coolShoes);

      
   }
}
