Finding child classes from the parent class [duplicate]

This question already has an answer here:

• At runtime, find all classes in a Java application that extend a base class 11 answers
• Accessing every child class of parent class in Java 3 answers

Imagine the parent class is provided and all the inherited classes have to be found. Can we do this using Java Reflection? The superclass can be of course found using the getSuperClass, but is there a way to find the child classes from the super class?
