Display All Module Names in Java 9

In Java 9, the module concept has introduced. It is a named, self-describing collection of code and data. The code can be organized as a set of packages containing types like java classes and interfaces, and data includes resources and other kinds of static information. A module contains a name, dependencies, and exported packages.

Syntax

module com.tutorialspoint.mymodule {
   // some statements
}

In the below example, we can able to display all module names by using the ModuleLayer class.

Example

public class AllModulesNamesTest {
   public static void main(String args[]) {
      ModuleLayer.boot().modules().forEach((module) -> {
         System.out.println(module.getName());
      });
   }
}
