Learn Java from Scratch - A Beginner's Guide - Step 06 - Java Modularization - 03 - Splitting Service and Consumer into

The video tutorial explains how to create and manage Java modules for service and consumer projects. It covers the creation of module-info.java files, resolving compilation errors, and using exports for encapsulation. The tutorial highlights the differences between modules and regular Java projects, emphasizing the control and encapsulation benefits of modularization.

What is the primary difference between a module and a normal Java project?

• Modules have a module-info.java file.

• Modules are only for consumer projects.

• Modules can use hyphens in their names.

• Modules do not require a name.

How should a module be named in Java?

• Using only numbers.

• Using random characters.

• Similar to how packages are named.

• With hyphens separating words.

What should you do if a consumer module has a compilation error due to missing service module access?

• Add the service module to the module path.

• Ignore the error.

• Delete the consumer module.

• Rename the consumer module.

What is the purpose of the 'requires' directive in module-info.java?

• To export all classes in a module.

• To specify dependencies on other modules.

• To rename a module.

• To delete a module.

Why might a logger in a consumer module cause an error?

• The logger is not initialized.

• Java logging module is not required.

• The logger is private.

• The logger is public.

What does modularization in Java help achieve?

• Unlimited access to all classes.

• Faster compilation times.

• Automatic error correction.

• Encapsulation and controlled access to module classes.

How can a service module control which packages are accessible to consumers?

• By deleting the packages.

• By renaming the packages.

• By using the 'exports' directive.

• By using the 'requires' directive.
