The general code is like this, and I feel that the code using the intermediary mode is similar, so I won't introduce it much here. The code in the book has advantages, but I don't feel that there is much difference, so I no longer use the intermediary mode to write code here. State mode is an unusually excellent mode, which may be the best way to solve some requirement scenarios. Although the state mode is not a simple to clear mode (it often brings about an increase in the amount of code), once you understand the essence of the state mode, you will certainly thank it for its incomparable benefits in the future. The key to the state mode is to distinguish the internal state of things. Changes in the internal state of things often bring about changes in the behavior of things. This article describes the state mode in detailPrivate State state;一天，小咕提出想回家和伙伴们在一起。康一为了让小咕了解外面的世界，悄悄把它带了出去。小咕发现环境已经面目全非，大吃了一惊，这个不适合就河童生存的地方根本就找不到伙伴。看到小咕难过，康一也不好受。他和小咕一起外出旅行，来到了还保存着河童传说的远野县。两人在美丽的大自然中找到了适合河童生活的地方，小咕愉快地在清澈的河里游了起来，康一也为它高兴。可是，在这里也怎么都找不到其它河童。康一听到村民们说“抓住一只河童能得一千万呢！”，赶忙带着小咕离开了那里。这还不算，偏张家又不乐意了，竟是好说歹说，也不肯再应承这门亲，她越发气得肝疼——自己想求的，人家还不要。
