Learn Java from Scratch - A Beginner's Guide - Step 05 - Java Modularization - 02 - Splitting Service and Consumer into

The video tutorial discusses the importance of modularization in software development. It highlights the problem of direct consumer access to algorithms, which can lead to issues when changes are made. The tutorial explains how to split a project into multiple JAR files to enforce modularization and resolve compilation errors by setting the classpath. Despite these efforts, the video notes that consumers can still access algorithms directly, and suggests further exploration of modularization solutions.

What is the main issue when a consumer directly uses a specific algorithm instead of the intended utility interface?

• It allows for easier debugging.

• It prevents the ability to switch algorithms without affecting consumers.

• It increases the performance of the application.

• It enhances the security of the application.

Why is modularization important in managing dependencies and interfaces?

• It simplifies the user interface design.

• It reduces the need for documentation.

• It helps in organizing code and managing dependencies effectively.

• It allows for faster execution of code.

What is the purpose of creating separate service and consumer JARs?

• To increase the size of the project.

• To manage dependencies and separate concerns.

• To make the project more complex.

• To reduce the number of classes in the project.

How can you manage dependencies between different JAR files in a Java project?

• By avoiding the use of any external libraries.

• By using a single JAR file for the entire project.

• By adding the required JARs to the classpath.

• By writing all code in a single class.

What happens when you add a service JAR to the classpath of a consumer JAR?

• The service JAR is deleted.

• The consumer JAR runs independently of the service JAR.

• The service JAR becomes inaccessible.

• The consumer JAR can access the classes in the service JAR.

What is a limitation of using separate JARs and classpaths in Java projects?

• It prevents the use of any algorithms.

• It does not prevent direct access to algorithms.

• It makes the project run slower.

• It increases the complexity of the code.

What is the next step after identifying the limitations of using separate JARs?

• To stop using Java for the project.

• To merge all JARs into a single file.

• To explore how modularization can provide a solution.

• To ignore the limitations and continue.
