1、原型模式

package com.yqj.pattern.prototype.improve;

public class Sheep implements Cloneable {
    
    private String name;
    private int age;
    private String color;

    public Sheep(String name, int age, String color) {
    
        this.name = name;
        this.age = age;
        this.color = color;
    }

    public String getName() {
    
        return name;
    }

    public void setName(String name) {
    
        this.name = name;
    }

    public int getAge() {
    
        return age;
    }

    public void setAge(int age) {
    
        this.age = age;
    }

    public String getColor() {
    
        return color;
    }

    public void setColor(String color) {
    
        this.color = color;
    }

    @Override
    public String toString() {
    
        return "Sheep{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", color='" + color + '\'' +
                '}';
    }

    @Override
    protected Object clone() {
    
        Object sheep = null;
        try {
    
            sheep = super.clone();
        } catch (CloneNotSupportedException e) {
    
            e.printStackTrace();
        }
        return sheep;
    }
}


package com.yqj.pattern.prototype.improve;

public class Client {
    
    public static void main(String[] args) {
    
        Sheep sheep = new Sheep("tom", 1, "白色");
        Sheep sheep2 = (Sheep) sheep.clone();
        Sheep sheep3 = (Sheep) sheep.clone();
        System.out.println(sheep+" hashcode:"+sheep.hashCode());

JS重写Date函数，兼容IOS系统_date.prototype 将所有 ios-程序员宅基地

文章浏览阅读1.8k次，点赞5次，收藏8次。IOS系统Date的坑要创建一个指定时间的new Date对象时，通常的做法是：new Date("2020-09-21 11:11:00")这行代码在 PC 端和安卓端都是正常的，而在 iOS 端则会提示 Invalid Date 无效日期。在IOS年月日中间的横岗许换成斜杠，也就是new Date("2020/09/21 11:11:00")通常为了兼容IOS的这个坑，需要做一些额外的特殊处理，笔者在开发的时候经常会忘了兼容IOS系统。所以就想试着重写Date函数，一劳永逸，避免每次ne_date.prototype 将所有 ios
