JAVA Rtti Type Information

RTTI allows you to discover and use type information while the program is running.

Dynamically bound method: Dynamic binding methods.

Polymorphism: polymorphic.

The implementation principle of Rtti:

Class object: Contains information about the class. Each class has a class object. When you create an instance of a class, the JVM uses the class loader subsystem.

ClassLoader: All classes are dynamically loaded into the JVM when they are used for the first time. This class is loaded when the program creates a static member reference for the first class.

Dynamic Loading: not fully loaded until the Java program starts to run. Instead, it is dynamically loaded when needed.
