a) Create a data structure, UserStore (.h) to store User objects, with the following features:

public class Plant {   protected String plantName;   protected String plantCost;    public void setPlantName(String userPlantName) {      plantName = userPlantName;   }    public String getPlantName() {      return plantName;   }    public void setPlantCost(String userPlantCost) {      plantCost = userPlantCost;   }    public String getPlantCost() {      return plantCost;   }    public void printInfo() {      System.out.println("   Plant name: " + plantName);      System.out.println("   Cost: " + plantCost);   }} public class Flower extends Plant {    private boolean isAnnual;   private String colorOfFlowers;    public void setPlantType(boolean userIsAnnual) {      isAnnual = userIsAnnual;   }    public boolean getPlantType(){      return isAnnual;   }    public void setColorOfFlowers(String userColorOfFlowers) {      colorOfFlowers = userColorOfFlowers;   }    public String getColorOfFlowers(){      return colorOfFlowers;   }      @Override   public void printInfo(){…

Subclass toString should call include super.toString(); re-submit these codes.   public class Vehicle {      private String registrationNumber;      private String ownerName;      private double price;      private int yearManufactured;      Vehicle [] myVehicles = new Vehicle[100];          public Vehicle() {          registrationNumber="";          ownerName="";          price=0.0;          yearManufactured=0;      }      public Vehicle(String registrationNumber, String ownerName, double price, int yearManufactured) {          this.registrationNumber=registrationNumber;          this.ownerName=ownerName;          this.price=price;          this.yearManufactured=yearManufactured;      }      public String getRegistrationNumber() {          return registrationNumber;      }      public String getOwnerName() {          return ownerName;      }      public double getPrice() {          return price;      }      public int getYearManufactured() {          return yearManufactured;      }…

1 using static System.Console; 2 class ShapesDemo 3 { static void Main() { abstract class GeometricFigure Create an application named ShapesDemo that 4 creates several objects 5 that descend from an abstract class called 7 { GeometricFigure . Each 8 public int Height { 10 11 9 GeometricFigure get includes a height , a { 12 13 width , and an area. return height; } 14 15 Provide get and set set { 16 17 accessors for each field height = value; except area ; the area } 18 is computed and is read- } only. Include an abstract 19 public int Width 20 { 21 22 method called get ComputeArea() that { computes the area of the 23 24 return width; GeometricFigure . 25 26 27 28 29 set Next you will create three { width = value; additional classes derived from the } 30 } 31 GeometricFigure class. Name these derived classes: Rectange , 32 public int Area 33 { 34 Square , and Triangle. get 35 { 36 37 return area; } 38 } 39 40 private void CalArea() 41 { 42 43 } 44 area = Height * Width; 45 } 46

Exercise 1-Account class • Design a class named Account that contains : • A private int data field named id for the account • A private double data field named balance for the account • A privet Date data field named dateCreated that stores the date when the account was created • A no-arg constructor that creates a default account • A constructor that creates an account with the specified id and initial balance • The getters (i.e., accessors) and setters (i.e., mutators) methods for id and balance • The getter method for dateCreated • A method named withdraw that withdraws a specified amount from the account • A method named deposit that deposits a specified amount to the account

Create a Class called Transaction with: instance variables: stock - your stock class type - char -> b or s (buy/sell) quantity - can be fractional price - buy/sell price when - LocalDate   constructors: constructor with parameters for stock, type and quantity. - sets the price from the stock price instance variable - sets when from LocalDate   getters and setters for each instance variable
