原型模式 java版

抽象原型 Prototype.java

public abstract class Prototype implements Cloneable{
    protected String name;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
                         
    @Override
    protected Object clone() throws CloneNotSupportedException {
        // TODO Auto-generated method stub
        return super.clone();
    }
}

具体原型 ConcretePrototype.java

public class ConcretePrototype extends Prototype {
}

测试类 Test.java

public class Test {
    public static void main(String[] args) throws CloneNotSupportedException {
               
        Prototype p = new ConcretePrototype();
        p.setName("zhangsan");
        System.out.println(p.getName());
               
        Prototype p2 = (Prototype) p.clone();
        System.out.println(p2.getName());
    }
}

测试结果：
