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.

To encapsulate the policy pattern in one sentence is to "encapsulate each algorithm into a different policy class so that they can be interchanged". The following is the structure diagram of the policy mode:

To enter oneself for an examination in the flight college, one must first have two physical examinations 2 or 3 months before the college entrance examination. The first is the preliminary examination, which is generally divided into four major subjects: ophthalmology, otolaryngology, surgery and internal medicine. Applicants are generally required to check ophthalmology first, because ophthalmology has the highest elimination rate. Most applicants will be eliminated in this subject, and future subjects will not have to be checked. When I applied for the examination that year, there were 10 boys in the whole school. As a result, 7 boys were brushed off in the first round of ophthalmology. Ophthalmology mainly examines vision and fundus, requiring normal vision and free from myopia, hyperopia, trachoma and other diseases, as well as color blindness, color weakness and other defects. Pilots use a special "C" table to check their eyesight, with 8 directions. It is far more difficult than the "E" table.
