Module
A module is a JAR with a module descriptor, available to the JVM on the module path.
Modulepath
All the code on the modulepath lives in their own "named" modules.
Package Relationship to Modules
A package can only be accessed from one module. Hierarchical packages are treated as separate, so "java.util" and "java.util.logging" can exist in different modules. Only public fields and methods are accessible in the code of exported packages of other modules.
Classpath
All the code from classpath lives together in the "unnamed" module.
Organizatorium
- Classpath and module path is mutually exclusive.
