problem: class T is responsible for two different duties: responsibility P1, Responsibility P2. When a class T needs to be modified due to a change in the duty P1 requirements, it is possible to cause a normal function to malfunction P2 functionality.Solution: Follow a single responsibility principle. Set up two classes T1, T2 respectively, so that T1 complete the functions P1 function, T2 complete functions P2 function. In this way, when the class T1 is modified, the responsibility is not P2 t
