Tackle practical coding exercises on Java exceptions to build foundational understanding, with short explanations and ongoing new exercises and solution videos guided by learner feedback.
Implement a divide function that returns the quotient of two numbers and throws a no divide exception when the second number is zero, while defining the exception class with constructors.
Learn to implement a bank account class with withdraw and deposit, enforce nonnegative balance using BankException (a checked exception), and validate balance with setBalance.
Implement a static size method that accepts a Path and returns its size using Files.size, wrapping any IOException in a FilesUtilsException with a descriptive message.
Discover solutions to every coding exercise, and request short explanation videos for any exercise. We’ll support you with additional exercises to help you excel.
Exception handling is a critical skill for every Java developer. This course is designed to deepen your understanding of how Java handles errors and provide you with the tools to write robust, reliable applications.
Through a focused set of hands-on coding exercises, you will learn how to anticipate, catch, and manage exceptions effectively. The course includes more than 10 practical exercises, each crafted to help you internalize key concepts and apply them in real-world scenarios. More exercises will be added over time based on student feedback and learning needs.
What You’ll Learn:
How to use try, catch, finally, and throw effectively
The difference between checked and unchecked exceptions
How and when to create your custom exceptions
Best practices for writing clean, maintainable error-handling code
Strategies for avoiding common exception-related pitfalls
This course goes beyond theory—it’s built to provide you with real-world experience through coding. Whether you're preparing for technical interviews, working on production code, or looking to reinforce your Java fundamentals, this course will strengthen your confidence in handling exceptions.
