This module guides learners through robust exception handling in Java, including the use of try-catch-finally and try-with-resources statements. It also covers formatting and localizing data such as numbers and dates, and demonstrates how to support multiple languages and regions using resource bundles. By the end, learners will be able to build applications that are both resilient to errors and adaptable to diverse user environments.

This module introduces the Java Platform Module System (JPMS), guiding learners through creating, running, and managing modular Java applications. You will explore module dependencies, services, command-line tools, and migration strategies to modularize existing codebases. By the end, you'll understand how to structure, analyze, and optimize Java applications using modules.

This module introduces the principles and practices of concurrent programming in Java, including thread management, synchronization, and safe data sharing. Learners will explore the Concurrency API, thread pools, atomic classes, and techniques for identifying and resolving threading issues. By the end, you'll be able to write efficient, thread-safe code for modern applications.

This module introduces Java's file and stream I/O capabilities, including working with files and directories using both legacy and NIO.2 APIs. Learners will practice reading, writing, and serializing data, as well as handling user input and traversing directory structures. Advanced topics such as file attributes, symbolic links, and exception handling are also covered.
