Learn Java from Scratch - A Beginner's Guide - 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, improving encapsulation and application modularity. The tutorial demonstrates listing JDK modules and discusses module dependencies and export statements. It concludes with a preview of modularizing applications.

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

• To modularize the JDK

• To increase the size of the JDK

• To simplify Java syntax

• To remove the RT.jar file

How does Java modularization benefit developers when building applications?

• By reducing the number of available modules

• By allowing the use of the entire JDK only

• By enabling the selection of specific modules needed

• By making all modules mandatory

Which module is considered the base module in Java's modular system?

• JDK.compiler

• Java.base

• Java.sql

• Java.logging

What is the purpose of export statements in Java modules?

• To hide packages from other modules

• To make packages available to other modules

• To delete unused packages

• To rename packages

Which of the following is a tool-related module in Java?

• Java.sql

• JDK.jshell

• Java.base

• Java.xml
