Java Subclass Inheritance of Parent Class Instance-Code Implementation of Pizza Selection

Write a program to implement pizza making. Requirements description Write a program to receive user input information and select the pizza to be made. Available pizzas include: bacon pizza and seafood pizza.

Implementation ideas and key code

1)Analyze bacon pizza and seafood pizza

2)Define the pizza class

3)Properties: Name, Price, Size

4)Method: Display

5)Define bacon pizza and seafood pizza inheriting from the pizza class

6)Define the pizza factory class, generate specific pizza objects based on input information

Pizza.java

package zuoye;
import java.util.Scanner;
//Superclass
public class Pizza {
	String name;
	double price;
	int size;
	public Pizza(String name){
		this.name=name;
	}
	public void display(){
		Scanner sc=new Scanner(System.in);
		System.out.println("Please enter pizza size:");
		size=sc.nextInt();
		System.out.println("Please enter pizza price:");
		price=sc.nextDouble();
	}
}

PeiGen.java

package zuoye;
import java.util.Scanner;
//Subclass bacon pizza
public class PeiGen extends Pizza {
	// double weight;
	public PeiGen(String name) {
		super(name);
	}
	public double peigen() {
		System.out.println("Enter bacon weight:");
		Scanner s = new Scanner(System.in);
		return s.nextDouble();
	}
}

SeaFood.java

package zuoye;
import java.util.Scanner;
//Subclass seafood pizza
public class SeaFood extends Pizza{
	public SeaFood(String name) {
		super(name);
	}
	public String seafood() {
		System.out.println("Enter seasoning information:");
		Scanner s=new Scanner(System.in);
		String peiliao=s.next();
		return peiliao;
	}
}

Work.java

package zuoye;
import java.util.Scanner;
public class Work {
	public static void main(String[] args) {
		System.out.println("Please select the pizza you want (1.Bacon Pizza 2.Seafood Pizza());
		Scanner s = new Scanner(System.in);
		int n = s.nextInt();
		if (n == 1) {
			PeiGen pg = new PeiGen("Bacon Pizza");
			double b=pg.peigen();
			pg.display();
			System.out.println("Name" + pg.name + "\nPrice:" + pg.price + "\nSize:" + pg.size + "\nBacon weight:" +b);
		} else if (n == 2) {
			SeaFood sf = new SeaFood("Seafood Pizza");
			String a=sf.seafood();
			sf.display();
			System.out.println("Name" + sf.name + "\nPrice:" + sf.price + "\nSize:" + sf.size + "\nIngredients:" +a);
		}
	}
}
