![]() You lose compile type checking, code analysis (like call hierarchies in an IDE) becomes more difficult, and renaming the methods requires changing the strings. they can be called after creating the Object of the class. Not an answer, but: Be aware that while using reflection is technically possible, it's probably not a good idea. Instance method(s) belong to the Object of the class, not to the class i.e.They can be called within the same class in which they reside or from the different classes defined either in the same package or other packages depend on the access type provided to the desired instance method. Memory allocation: These methods themselves are stored in Permanent Generation space of heap but the parameters (arguments passed to them) and their local variables and the value to be returned are allocated in stack. The class provides APIs to access information about a methods modifiers, return type, parameters, annotations, and thrown. ![]() Return type can be int, float String or user defined data type.

Using java reflection we can inspect a class, interface, enum, get their structure, methods and fields information at runtime even though class is not accessible at compile time. Reflection in Java is one of the advance topic of core java. Example passing static method names to a parameterized unit test. Java Reflection provides ability to inspect and modify the runtime behavior of application. If you have parameters, you have to pass them in like this. ![]() Java Programming - Beginner to Advanced Note: This static method is parameterless. class) Map hm new HashMap<> () method.
