Summary: In this video we will wrap up our discussion on Java Development. We will tackle questions that discuss packages, jar files and classpath(s). First, we will start with system properties. System properties can be specified at the command line and programmatically. However, a property specified programmatically will take precedence over the value specified at the command line. We will see a question that covers this concept. Next, we will talk more about creating jar files and how we can reference them with the classpath. We will be given a directory structure that contains java files and jar files. We need to choose the correct command line option that references the jar file.
