Is Reflection good in Java?

Reflection is often used as part of software testing, such as for the runtime creation/instantiation of mock objects . Reflection is also a key strategy for metaprogramming. In some object-oriented programming languages such as C# and Java, reflection can be used to bypass member accessibility rules.

There are good points to Reflection. It is not all bad when used correctly; it allows us to leverage APIs within Android and also Java . This will allow developers to be even more creative with our apps. There are libraries and frameworks that use Reflection; a perfectly good example is JUnit.

Java Reflection makes it possible to inspect classes, interfaces, fields and methods at runtime, without knowing the names of the classes, methods etc. at compile time . It is also possible to instantiate new objects, invoke methods and get/set field values using reflection.1 Eyl 2008
