Each object has its corresponding state, and each state corresponds to some corresponding behaviors. If an object has multiple states, there will be many behaviors. Then the judgment of these states and the behavior completed according to the states will lead to multiple conditional statements, and if a new state is added, the existing code needs to be changed. This kind of design obviously violates the principle of opening and closing, and the state mode is used to solve such problems.

Don't blindly follow the trend of worship, classics will never be out of date, reading more books/videos/excellent blogs is much better than following the trend without brains.
