![]() Right now the only alternative is to use reflection to instantiate the class. Another problem is that despite assertions to the contrary, if you compile your Java classes with a version of the JVM and they instantiate by reflection with a. That is, using SecretAnnex secret = new SecretAnnex(). Similar to methods, reflection provides APIs to discover and retrieve the constructors of a class. Typically it performs operations required to initialize the class before methods are invoked or fields are accessed. We will be using the below methods from Class. To do that, you need to have an instance of outer class and invoke the inner class. In this article, we will see how to create an instance of class in a type safe manner using java reflection. Many of open source framework, uses reflection to create instance or Object at runtime, based upon the name of the class. At this point we have created a class SecretAnnex that can not be instantiated in the normal way. A constructor is used in the creation of an object that is an instance of a class. Yes, you can instantiate a private inner class with Java reflection. Here is my rendition of the SecretAnnex…. ![]() (1) Provided that the code has not been obfuscated and (2) that a security manager with restricted policy is not in place. ![]() As Uncle Ben quoted in a famous movie, “With great power comes great responsibility”, Reflection allows us to circumvent a private constructor provided two things do not exist. Java Reflection gives to the programmer quite a bit of power and allows you to do all sorts of things you never thought possible.
