Explain the template method mode, which means: in an abstract class, there is a main method, and then define 1... n methods, which can be abstract or actual methods, define a class, inherit the abstract class, override the abstract method, and realize the call to subclasses by calling the abstract class. First look at a diagram:Bss_addr=elf. Symbols ['__bss_start']Aviation units mainly carry out tactical training, combined with combat missions, focusing on combat technology and tactical application training to improve their ability to carry out missions under complex conditions. Every year, tactical, technical, theoretical and physical assessment is organized, and flight grade assessment is carried out, and pilots of Grade I, II and III are respectively assigned. The purpose of aviation unit training is to enable each pilot to master the combat technology of advanced aircraft and be able to undertake combat missions.However, that implementation of individual step at a more detailed level may differ, and we usually consider use the template method pattern to handle it
