Constructors: Exam questions tests - Sun Certified Java Programmer 310-065 - Lesson 51 | Java courses

In this video we will see constructors, inheritance, methods versus constructors and the Comparable interface.

Duration: 15:48 minutes

Summary: In this video, we keep going with the long list of exam questions. The items we are concentrating on are: constructors, inheritance, methods versus constructors, and the Comparable interface. One important item you need to be careful about as a test taker is the names of methods that match the name of the class to confuse the reader. In this video, you will see multiple methods with the same name but different signature that look like constructors. Keep in mind that these methods return values, but constructors don’t (not even void). Another item of importance is that the order of the calls when using multiple inheritance. With initialization, we start with the top class and go down to the bottom. You also need to be aware of the implicit call to super. Finally, you need to know the important constructors (like Comparable) and the method(s) they contain. Knowing these methods and their implementations is critical to passing the exam.
