1、问题描述

小明家有两个工厂，一个用于生产圆形积木，一个用于生产方形积木，请你帮他设计一个积木工厂系统，记录积木生产的信息。
输入案例

3
Circle 1
Square 2
Circle 1

2、工厂模式

将产品的创建过程封装在⼀个⼯⼚类中，把创建对象的流程集中在这个⼯⼚类⾥⾯
看图

3、解决方案

import java.util.*;

public class Main{
    public static void main(String[] args){
        Scanner sc=new Scanner(System.in);
        int number=sc.nextInt();
        sc.nextLine();
        for(int i=0;i<number;i++){

            String s=sc.nextLine();

            String[] arr=s.split(" ");
            int count=Integer.parseInt(arr[1]);

            if(arr[0].equals("Circle")){
                Factory factory=new CircleFactory();
                Blocks circleInstance=factory.createBlocks();
                for(int j=0;j<count;j++){
                    circleInstance.draw();
                }

            }else if(arr[0].equals("Square")){
                Factory factory=new SquareFactory();
                Blocks squareInstance=factory.createBlocks();
                for(int j=0;j<count;j++) {
                    squareInstance.draw();
                }
            }

        }
    }
}

interface Blocks{
    void draw();
}
class CircleBlocks implements Blocks{

    @Override
    public void draw() {
        System.out.println("Circle Block");
    }
}
class SquareBlocks implements Blocks{

    @Override
    public void draw() {
        System.out.println("Square Block");
    }
}

interface Factory{
    Blocks createBlocks();
}

class CircleFactory implements Factory{
    public CircleBlocks createBlocks(){
        return new CircleBlocks();
    }
}

class SquareFactory implements Factory{
    public SquareBlocks createBlocks(){
        return new SquareBlocks();
    }
}
