Basic introduction
The defining feature of Java 9 is a new module system. As code bases get larger, the chances of creating complex, convoluted "spaghetti code" increase exponentially. At this time, you have to face two basic problems: it is difficult to truly encapsulate the code, and the system does not have a clear concept of the dependencies between different parts (that is, JAR files). Every public class can be accessed by any other public class on the classpath, which can lead to inadvertent use of APIs that are not intended to be publicly accessible. In addition, there are problems with the classpath itself: how do you know that all the required JARs are already there, or if there are duplicate entries? The module system solves both problems.
