It is also possible to instantiate new objects, invoke methods and get/set field values using reflection. at compile time. Earlier in this article series, you learned how reflection performance is many times slower than direct access, and then learned about classworking with Javassist and the Apache Byte Code Engineering Library (BCEL). For example, your image in a mirror, or a reflected image of a tree on a lake. The name parameter is a String specifying the simple name of the desired method.. It enables us to explore not only the intrinsic nature of the class but also instantiate one without using an explicit new operator at runtime. at run time and to defer the decision on … The java.lang.Class class provides many methods that can be used to get metadata, examine and change the run time behavior of a class.. org.easytesting » fest-reflect Apache.
