Pick a pair of concrete classes in the JDK in a parent-child relationship and discuss a few overridden and overloaded methods. Read the threads posted before your own post to make sure you are using an example that has not been used already. Make sure to properly reference your sources. Do not use Object as the parent class - it is too trivial to address the issues to be addressed here, and in any case, Object is the final parent of all classes in Java. Similarly, do not use the toString method and all other methods defined for the Object class as an example of overridden method.
