原型模式

浅克隆

@Override
protected Object clone() throws CloneNotSupportedException {
    return super.clone();
}

深度克隆

@Override
protected Object clone() throws CloneNotSupportedException {
    Object obj = super.clone();
    Video v=(Video) obj;//将属性进行深克隆
    v.createTime=(Date) this.createTime.clone();
    return obj;
}

 

 代码实现

public class BiliBili {
    public static void main(String[] args) throws CloneNotSupportedException {
        Date data = new Date();
        Video v1 = new Video("java", data);
        Video v2 =(Video) v1.clone();
        System.out.println("v1="+v1);
        System.out.println("v2="+v2);
        System.out.println("v1="+v1.hashCode());
        System.out.println("v2="+v2.hashCode());
        System.out.println("==================");
        data.setTime(222232521);
        System.out.println("v1="+v1);
        System.out.println("v2="+v2);
