实例方法

The concept of instance methods has a wide range of potential applications, especially for object-oriented programming. They are related to the concept of object-oriented programming in that these methods operate on an instance of a particular type of object, either at compile-time or at runtime.
Instance methods are implemented in a class definition, and serve as a basic component of object-oriented programming. In general, instance methods provide a mechanism for objects within a project to interact with one another and access the resources and data within a program. Instance methods are often provided with a unique object identifier, that is unique within the context of the program, and which can be used to reference the instance upon which the method is called. In addition, they may be able to take parameters that can adjust their behavior or provide additional information.
Typically, instance methods are declared within a class or struct, and can be called directly by their name, such as with the instance.methodname() syntax. This allows both the programmer and the compiler to identify the method, and also allows them to specialize their behavior based on the instance that is calling the method.
Instance methods are an important part of object-oriented programming, as they provide a means of encapsulating the operations that an object can perform, as well as defining how the object interacts with other objects. By controlling the access to the methods of an object, a programmer can ensure that the object behaves in a specific way, and provide a template for what the object should do. As a result, instance methods help to structure the way a program works, and simplify the development process.
