Question

1. Create a class Car with data: Name, Price, Production and properly methods.

2. Create another class named GenericCar with a parameter of the T type. This class manages a collection of object T (may be LinkedList) named a. Implementing some methods for GenericCar:

• Add: add new item of T to a
• Display: display all items of a
• getSize: return the number item of a
• checkEmpty: check and return whether a is empty or not
• delete(int pos): remove the item at the position pos of a.

Write a program to use GenericCar as above menu.

Make your own main program to test all above methods.

Answer 1

TestCar.java

--------------------------------

package com.data.structure;

import com.faisal.checgg2.com.Car;

public class TestCar {
//starting point of the program
   public static <T> void main(String[] args) {
       // creating the object of GenericCar
       GenericCar car=new GenericCar();
       // adding the Car item into the list
       car.add(new Car("Ferari",1500000.0,"Red in color"));
       car.add(new Car("Alto",1700000.0,"white in colore"));
       car.add(new Car("Enova",1500000.0,"black in color"));
       // Display all item from List
       car.display();
       // fetch the size of all item in the List
       int itemSize=car.getSize();
       System.out.println("Number of item in the List :"+itemSize);
       // check the List is Empty or Not
       String chkEmpty=car.checkEmpty();
       System.out.println("List is Empty or Not : "+chkEmpty);
       // Delete a perticuler item from List
       car.delete(2);
       System.out.println("---After deletion of item 2---");
       // Again Display all item from List
       car.display();
   }

}

GenericCar.java

----------------------------

package com.data.structure;

import java.util.ArrayList;

import com.faisal.checgg2.com.Car;

public class GenericCar<T> {
   ArrayList<Car> carList=new ArrayList<Car>();
// below method used to add Car item in the List
   public void add(Car car) {
       carList.add(car);
      
   }
// below method is used to display all item in List
   public void display() {
  
       for(Car car: carList) {
           System.out.println("Name :"+car.getName()+", Price :"+car.getPrice()+", Production :"+car.getProduction());
       }
      
   }
   // below method is used to get the size of List
   public int getSize() {
       return carList.size();
      
   }
   // below method is used to check item List is Empty or Not
   public String checkEmpty() {
       if(carList.size()>0) {
           return "Not Empty";
       }
       return "Empty";
   }
//// below method is used to delete a item from List
   public void delete(int n) {
       if(carList.size()>n) {
           carList.remove(n);
           System.out.println("Item deleted from List At Index : "+n);
       }
      
   }

}
---------------------------

Car.java

---------------------------

package com.faisal.checgg2.com;

public class Car {
  
   String name;
   double price;
   String production;
   public Car(String name, double price, String production) {
       super();
       this.name = name;
       this.price = price;
       this.production = production;
   }
   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public double getPrice() {
       return price;
   }
   public void setPrice(double price) {
       this.price = price;
   }
   public String getProduction() {
       return production;
   }
   public void setProduction(String production) {
       this.production = production;
   }
  
  

}

SAMPLE OUTPUT:

Name :Ferari, Price :1500000.0, Production :Red in color
Name :Alto, Price :1700000.0, Production :white in colore
Name :Enova, Price :1500000.0, Production :black in color
Number of item in the List :3
List is Empty or Not : Not Empty
Item deleted from List At Index : 2
---After deletion of item 2---
Name :Ferari, Price :1500000.0, Production :Red in color
Name :Alto, Price :1700000.0, Production :white in colore
