What is module path in Java?

I'm happy to respond in English!

In Java, a module path refers to the path that points to a Java module's location. A Java module is a self-contained bundle of related classes, interfaces, and other resources that can be easily shared with other modules or applications. Think of it like a self-sufficient package that includes everything needed to use its contents.

When you create a Java module, you specify the module path during the compilation process using the --module-path option with the javac compiler. This tells the JVM (Java Virtual Machine) where to find the modules when your program runs. The module path can include directories or JAR files containing modules.

For example, suppose you have a directory called my-modules that contains several Java modules:

my-modules/
-- my-module1.jar
-- my-module2.jar
-- ...

To compile and use these modules in your program, you would add the module path as follows:

javac --module-path my-modules/ MyProgram.java

This tells the javac compiler to look for Java modules (.jar files) within the my-modules directory when compiling your program. When you run your program using the java command, the JVM will also search for these modules in the specified module path.

In addition to directories and JAR files containing modules, a module path can also include URLs pointing to remote repositories or archives (like ZIP files). This makes it easy to share and reuse Java modules across different projects or even organizations.

When you specify the module path during compilation, the JVM uses the information to resolve any dependencies between modules. For example, if my-module1 depends on my-module2, the JVM will ensure that both modules are loaded and available when running your program.

In summary, a module path in Java is a path that points to where a Java module's location can be found, which enables the JVM to load and use these self-contained bundles of classes and resources.
