Discussion:
Q1. There are numerous ways to test for equality. == works fine for primitive types, but not for objects such as strings, etc. Why is this so? Discuss why == doesn't work when utilizing Strings but does for integers and doubles.
Q2. Overloading is a way of using the same method name for multiple methods as long as the number / types of arguments are different. Why is overloading useful? Give an example of how this could be used.
