二十三种设计模式全面解析-原型模式（Prototype Pattern）详解：创造对象的奇妙之道

import java.util.ArrayList;
import java.util.List;
// 抽象汽车原型
abstract class CarPrototype implements Cloneable {
    protected String model;
    protected List<String> features;
    public CarPrototype() {

            e.printStackTrace();
        }
        return clone;
    }
}
// 具体汽车原型 - SUV
class SuvCar extends CarPrototype {

        for (String feature : features) {

}
// 具体汽车原型 - 轿车

}
// 客户端代码
public class CarFactory {
    public static void main(String[] args) {
        // 创建原型汽车对象
        CarPrototype suvPrototype = new SuvCar();

        // 克隆新对象
        CarPrototype clonedSuv = suvPrototype.clone();
        CarPrototype clonedSedan = sedanPrototype.clone();
        // 添加新特性
        clonedSuv.addFeature("4WD");
        clonedSedan.addFeature("Leather seats");
        // 打印新对象的特性
        clonedSuv.printFeatures();
        clonedSedan.printFeatures();
    }
