Why does Java support Reflection? The answer is that the Java runtime still has type information. It contains all the fields, methods, protection levels, and other classes that the class depends on. In Java, Class information is stored as objects.

Runtime polymorphism is the most powerful mechanism for code reuse in object-oriented programming. Dynamic concepts can also be said to be "one interface, multiple methods ". Dynamic method scheduling is the basis for Java implementation of runtime
