Join David Gassner for an in-depth discussion in this video Instantiating classes dynamically, part of Advanced Java Programming (2012).
I've previously described how to get a reference to an object's class by using the getClass method.…This method is defined in the object class, that's the ultimate super class of the entire…Java class hierarchy.…And so it's available in all objects and returns an instance of TheClassClass.…Once you have that, you can get the classes name and also references to all of the classes…members such as constructor methods, conventional methods, and fields.…
I'll describe how to do this with constructor methods.…I'm working in a project called TypeInfo.…This is similar to previous projects, but it has a couple of changes.…First of all, I've added a new enumerator class called OliveColor, and it's going to…be used eventually to manage the colors of the olives, so that instead of passing in…long values, I'll just name the color I want.…I'll start back in the Main class, and I'll place the cursor after the existing code.…My goal is to get a reference to all of the constructor methods of this class.…
I'll move the cursor after the call to the getSimpleName method, and I'll declare a new variable.…
