- You use the Cl forName method to get a Clobject for the clgiven in a parameter. Then you create an instance of this clusing the newInstance method. a Reflection provides a lot of information about a given clat runtime: you can easily know all its super . - The following example would find all subcl.es of MyClin the for a clwill include a list of known subcl.es and for interfaces, . - In some situations it may be necessary to identify all of the subtypes of a given clthat exist within anembly. Subcl.es cannot be read .Nevertheless, we note that most existing object-oriented programming languages do identify type and clas well as subtype and subcl That is, a clis .

Now you have a method that can find any subclof a given clin a given package. You can improve the method by letting it look for the subcl.es in the currently loaded packages. To do that, you use the Package.getPackages method, which returns the exact packages loaded by the current clloader..You should use polymorphism to try to avoid the need to check for the concrete subcl., but I can't tell you more with the information given..Subcl.es cannot be read directly from a base clbut can be easily determined using a simple query.
