Data Types and Exceptions in Java

About This Certificate

Java is a powerful, widely used programming language, and understanding how it handles data is essential for writing clean, effective code. This course gives you a practical introduction to Java’s data modeling, collections, and error-handling tools. Work with POJOs and Organize Code Start by learning how to model data using Plain Old Java Objects (POJOs) and wrapper classes. You'll also explore how Java uses packages to group related classes and keep code organized. Use the Collections Framework Get to know Java’s built-in data structures—Lists, Sets, Maps, and Queues—and learn how to use them to store and manage groups of objects in different ways. Handle Errors and Log Application Behavior Wrap up by learning to handle exceptions using try/catch blocks and throw custom errors when needed. You’ll also add logging to your code to track and understand your program’s behavior. By the end, you’ll be able to structure data, work with Java collections, and write more reliable, maintainable applications.
