What are best practices for working with classpath vs module path?

When working with Java, understanding the difference between the classpath and the module path is essential for organizing your applications properly. Here are some best practices:

• Use the Module Path for Modular Applications: If you are creating a modular application using Java 9 or later, make use of the module path to take advantage of module system features.
• Classpath for Legacy Applications: For older applications that do not use the module system, stick with the classpath.
• Consistent Dependency Management: Use build tools (like Maven or Gradle) to manage dependencies and define whether they should be on the classpath or module path.
• Clear Separation: Keep your modules and libraries organized, with a clear separation of what is available on the module path versus the classpath.
• Documentation: Document the purpose and structure of your modules and libraries to maintain clarity for future maintenance.
