Encapsulation - Exam questions tests - Sun Certified Java Programmer 310-065 - Lesson 68 | Java courses

In this video, we will learn that encapsulation makes it easier to reuse classes and makes better testing and higher reliability.

Duration:15:28 minutes.

Summary: In this video, we proceed with the second set of the Java certification exam. As you notice, we already finished the first 75 question-set and now we are tackling the next 75-question set. We start this video with the famous try/catch/block. By now, you should be familiar with this concept and the idea that finally is always called whether or not we have an exception. In the next question, we look at method declaration and static initialization. It is incorrect to have a method declared twice in the same class with the same signature, but one static and one instance declaration. Then, we see a question that tests us on the concept of encapsulation. We learn that encapsulation makes it easier to reuse classes and makes better testing and higher reliability. Finally, we look at a question that talks about system properties and how they get set.
