Summary: In this video, we continue the first sample exam. We cover 5 questions that have to do with static import, classpath, File class, System.console, and JVM. First of all there are questions on the exam that test you on your ability to remember classes and constructors. For example, the first question asks for the classes that take File as a parameter in their constructors. The answers were FileWriter, FileReader and PrintWriter. The second question tests your knowledge about System.console. The idea is that the JVM is not guaranteed to have a console. The third question has to do with jar files and classpath. Although this concept is confusing, it is very important for the exam. The file two questions, discussed static import and sorting ArrayLists. It is important to know the syntax of static import so you can tell the problem since the question is misleading by showing you potential problems with weird identifiers and variable declarations.
