What methods do you use to split monolithic components into modules?

There are several approaches to splitting monolithic components into modules in Java:

• Logical separation: Break down a large component into smaller ones responsible for specific functions or business logic.
• Use of packages: Organize code into packages to group related classes.
• Interfaces and abstractions: Define clear interfaces between modules for loose coupling.
• Java Module System (JPMS): Use module-info.java to explicitly define dependencies and export packages.
• Refactoring: Gradually extract reusable parts into separate modules or libraries.

For example, if a monolith has components for user management and orders, you can create two modules: user-service and order-service, each with its own responsibilities and API.
