Question

Create a public class called MedicalItem with the following specifications:It should have the following private instance variables:

An item number (int)

An item name (String)

Cost of the item (double)

It should have the following constructors:

A public no-args constructor that creates an Item with default values, item number = 0, item name = “” and item cost = 0.0

A public constructor that creates an item with the specified item number, item name and item cost

It should have the following public accessor (get) methods:

A method that returns the item number

A method that returns the item name

A method that returns the cost of the item

It should have the following public mutator (set) methods:

A method that changes the item cost to a specified new cost

It should have a toString() method that returns a string that describes the item, i.e. its number, name and cost.

Create a public class called TestMedicalItem with the following specifications:

It has a main method which creates 5 items with the following item numbers, item names and item costs:

1, “Bandage Gauze” , 0.50,

2, “Surgical Mask”, 1.00

3, “Tongue Depressors”, 0.75

4, “III Catheter”, 1.25

5, “IV Catheter”, 1.50

Displays the number, name and cost of the items by using the toString() method

Adds sales tax of 5% to the cost of each item and displays on screen the total amount for each item, i.e. item cost + sales tax

Explanation / Answer

Solution:

package com.nancy.chegg.qa;

public class MedicalItem {

   private int number;
   private String name;
   private double cost;
   MedicalItem() {
       this.number = 0;
       this.name = "";
       this.cost = 0.0;
   }

   MedicalItem(int number, String name, double cost) {
       this.number = number;
       this.name = name;
       this.cost = cost;
   }

   public int getNumber() {
       return number;
   }

   public String getName() {
       return name;
   }

   public double getCost() {
       return cost;
   }

   public void setCost(double cost) {
       this.cost = cost + cost * 0.05;
   }

//Calculating the total cost here
   public double totalAmt(double cost) {
       setCost(cost);
       return getCost();
   }

   public String toString() {
       return "num : " + number + " Name : " + name + " Cost : " + cost + " Total Cost : " + totalAmt(cost);
   }
}

package com.nancy.chegg.qa;

public class TestMedicalItem {

   public static void main(String[] args) {
       MedicalItem obj1 = new MedicalItem(1, "Bandage Gauze" , 0.50);
       MedicalItem obj2 = new MedicalItem(2, "Surgical Mask", 1.00);
       MedicalItem obj3 = new MedicalItem(3, "Tongue Depressors", 0.75);
       MedicalItem obj4 = new MedicalItem(4, "III Catheter", 1.25);
       MedicalItem obj5 = new MedicalItem(5, "IV Catheter", 1.50);

//implicitly call toString method.
       System.out.println(obj1);
       System.out.println(obj2);
       System.out.println(obj3);
       System.out.println(obj4);
       System.out.println(obj5);
   }

}

Sample run:

num : 1 Name : Bandage Gauze Cost : 0.5 Total Cost : 0.525
num : 2 Name : Surgical Mask Cost : 1.0 Total Cost : 1.05
num : 3 Name : Tongue Depressors Cost : 0.75 Total Cost : 0.7875
num : 4 Name : III Catheter Cost : 1.25 Total Cost : 1.3125
num : 5 Name : IV Catheter Cost : 1.5 Total Cost : 1.575
