Java Fundamentals: Reflection mechanism (Reflection) Summary

Reflection is of great significance in Java and is a dynamic mechanism for loading, detecting, and using classes that are completely unknown during compilation. In other words, a Java program can load a runtime to know the name of the class, learn its full construct (but not including the methods specific definition), and generate its object entities, or set values on its fields, or use its methods. Reflection is the basis of the framework, and the framework can greatly save the development cost of Java programs, is often encountered in the future work of the technology. Therefore, the importance of learning good reflection is self-evident.
