I didn't understand the previous code and it didn't run to my software . can you do it again? I use intelliJ IDE to code in JAVA. Thank you learnedbuilding a Team, and the Player for a sport and test them out with Iterators.PlayerThe players in the team should be represented by a Player class that has a name, and a position (theirnumber on the team). It also needs a default constructor (no arguments) that gives a default name andposition of 0. Two instances of Player are equal to each other when the name and position is equal.TeamA team has a name, a roster of players (an ArrayList), and a maximum number of players. Make use ofthe Iterator from the roster to implement the following:We'll becontains: Check if a Player is in the roster.insert: Insert a Player into the roster. Cannot add a duplicate player, and you cannot addmore than the maximum number of players. Throw an exception in those cases like so:public void makeError () throws Exception {}throw new Exception("This is an exception message.");iterator: A public method to expose the iterator for your roster of players.Don't use anything other than the iterator, size, and add method from your ArrayList variable. Let's run some tests to ensure that your code is running correctly!1. Create Team A, a team with the name "Tigers". Create another team, Team B, using the defaultconstructor. The maximum number of players should be 17.2.Add two players built with the default constructor to Team A and catch the exception that isthrown using a try/catch statement. In the catch section, print the stack trace or another helpfulmessage:try {throw new Exception ("This is an exception message.");}catch (Exception e) {e.printStackTrace ();3. Fill up both teams with players.4. Try inserting more players after filling them and handle the exception.5. Test to see if contains is consistent in its results.6. Finally, iterate over the team rosters and legibly output all the players.

All vehicles used for transportation in the U.S. must have identification, which varies according to the type of vehicle. For example, all automobiles have a unique Vehicle Identification Number (VIN) assigned by the manufacturer, plus a license plate number assigend by the state in which the auto is registerd. Modify the Auto class to include an instance variable for the license plate number. Implement the constructor so that an Auto can be constructed with a VIN and a license plate number. Override the getID() method to return the id of the auto as shown in this format: VIN=1234567890,plate=ABC123 (without any spaces). ** Represents an automobile.*/public class Auto // TODO: Inherit from Vehicle{ // TODO: Declare instance variables public Auto(String vin, String plate) { // TODO: Complete the constructor } // TODO: implement the getID() method for autos}
Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's 10.0 34.0 2.0 1.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is: Nutritional information per serving of None: Fat: 0.00 g…
The Doctor program described in Chapter 5 combines the data model of a doctor and the operations for handling user interaction. Restructure this program according to the model/view pattern so that these areas of responsibility are assigned to separate sets of classes. The program should include a Doctor class with an interface that allows one to obtain a greeting, a signoff message, and a reply to a patient’s string. To implement the greeting, define a method named greeting for the Doctor class. To implement the signoff message, define a method named farewell for the Doctor class. Both greeting and farewell should return a string with a greeting or farewell message respectively. The reply function is defined for you, it should be added as a method for the Doctor class. The rest of the program, in a separate main program module, handles the user’s interactions with the Doctor object. Develop this program with a terminal-based user interface. Note: The program should output in the…
The total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any changes at all to Product.java, and you should only add to ShoppingTripStartingCode.java. Do not change any code that is already present Example(Cheese and bread are necessities and soda and candy are luxuries)Cheese…
Write a class named Person with data attributes for a person’s name, address, and telephonenumber. Next, write a class named Customer that is a subclass of the Person class. TheCustomer class should have a data attribute for a customer number, and a Boolean data attributeindicating whether the customer wishes to be on a mailing list. Demonstrate an instance of theCustomer class in a simple program.
Make a class Person, with instance variable name, age, and gender. Make a class Employee inheritfrom Person, with extra data for salary, and hiring date. Make another class Student inherit from Person,with data for program name, level (undergraduate/graduate), and program year. Supply required methods forthe superclass and the subclasses. Make a subclass Manager from Employee, with bonus salary, andoverride the corresponding method(s). Provide toString method for the Employee class and its subclass,Manager, such that it returns employee name, type of the employment, and salary. For instance if you createan object, manager1, from Manager class, with name=”John Smith” and annual salary of $125,000 and bonusweekly bonus of $200, and then write a print statement like System.out.println(manager1); , the output willbe:John Smith, Manager, Salary = $125,000/year, Weekly bonus = $200

Now we are going to use the design pattern for collecting objects. We are going to create two classes, a class AmazonOrder that models Amazon orders and a class Item that models items in Amazon orders. An item has a name and a price, and the name is unique. The Item class has a constructor that takes name and price, in that order. The class also has getters and setters for the instance variables. This is the design pattern for managing properties of objects. The setName() method should do nothing if the parameter is the empty string, and the setPrice() method should do nothing if the parameter is not positive. The class also has a toString() method that returns a string representation for the item in the format “Item[Name:iPad,Price:399.99]”. For simplicity, we assume an Amazon order can have at most 5 items, and class AmazonOrder has two instance variables, an array of Item with a length of 5 and an integer numOfItems to keep track of the number of items in the…

Hi can you assist me on the problem below for a class and a test class that conforms to the following specifications: 1. The name of the class is RightTriangle 2. The class has member variables base and height 3. The class has a constructor that initializes base and height 4. The class has accessors and mutators for base and height 5. The class has a toString method that produces String representation of a RightTriangle like the following example for a triangle with base 12 and height 10. Base : 12 Height 10 6. The class has a method called findArea to compute the area of the right triangle. Here is a suggested implementation. public double findArea() { return 0.5* this.base*this.height; } 7. The class using proper naming conventions Write a test class called RightTriangleTest that conforms to the following: 1. Create an object with base = 10 and height = 20, for example myTriangle. 2. To print the toString for myTriangle. 3. To print the area of myTriangle. System.out.println(“The…
We have two classes, Person and Employee. Both have a field, firstName. We have instances of these objectsPerson p and Employee e. Both p and e have the same value for firstName, specifically, p.firstName = “joe”and e.firstName = “joe” Which of the following statements is necessarily true? Group of answer choices 1. p.equals(e) will return true because they contain the same firstName. 2. We don’t know if either class will have an equals method. 3. There is not enough information to tell what p.equals(e) will return. 4. p.equals(e) will return false but p == e will be true.
add a class to package that represents your new drivable type. That type should be something that is capable of being driven (speeding up and slowing down) and therefore a perfect candidate for a class that implements the actions in the Drivable interface.
