Summary: In this video, we continue our discussion of the Java certification exam. The first question talks about threads. We encountered many thread questions before, and we saw how to implement the Runnable interface. But one key point about threads is that it does not matter how long the first thread is running, when the second thread joins after the first, it executes after the first thread finished executing. The second question tests our ability of knowing how to declare and initialize an array. Remember that arrays use square brackets, not parentheses. In the third question, we are given two loops back to back. However, there were no curly braces given to wrap the statements in the loop. Therefore, only the first statement after the loop is the one that belongs to the loop. The fourth question discusses the process of serialization and de-serialization when a member is declared as transient.
