Referring here A is a precompiled Java class (I also have the source file) B is a Java class that I am authoring B extends A. How can logic be implemented such that A can call the methods that B has. The following are the conditions: I don't want to touch A(only as a last option though that is if no other solution exists). I don't want to use reflection. As stated, if needed I could modify A. What could be the possible solution either way?

Can a Parent call Child Class methods?
