Java Programming for Complete Beginners - Java 16 - Step 03 - Getting Started with Java Modularization

The video tutorial introduces Java modularization, a feature introduced in Java 9 to modularize the JDK. It explains the growth of RT.jar and how modularization allows developers to use only necessary modules, enhancing encapsulation and modularity. The tutorial demonstrates listing modules in Java 16 and discusses module dependencies, highlighting Java.base as the default module. It concludes with a preview of modularizing applications, comparing traditional and modular approaches.

What was one of the main reasons for introducing modularization in Java 9?

• To modularize the JDK and allow selective usage of modules

• To increase the size of the JDK

• To make Java programs run faster

• To remove the need for Java updates

How does Java 9 modularization benefit developers?

• By making Java programs less secure

• By allowing them to choose only the modules they need

• By increasing the complexity of Java applications

• By forcing them to use all available modules

Which command is used to list the available modules in the JDK?

• java -version

• java -modules

• java -list

• java -compile

What is the role of the Java.base module?

• It is used only for database connectivity

• It is the foundational module required by all Java programs

• It is a module for graphical user interfaces

• It is an optional module for advanced features

What do export statements in Java modules do?

• They increase the size of the module

• They delete unused packages

• They make packages available to other modules

• They hide packages from other modules
