How To: Java Reflection for has-a-relationship?

Dear Ranchers,

I'm willing to define a map with key as methodName and value as related 'java.lang.reflect.Method'. However the problem is, to get the methods of the class member -[which should/is an user defined class/object].

e.g:


So, how can I solve:

1. Get methods dynamically [java.lang.reflect] of class B [eg: class/es which has specific annotation '@Entity'], within/from class A?
2. Both the classes has same field type & name 'String value'. How to add/get it to/from my map collection?

Note: Using HashMap<String,Method>.

Thank you in advance!

Too difficult a question for beginners. Moving.
