Java Webinar IV – Exception Handling, Debugging, and Robust Programs

Duration: 3 Hours
Level: Early Intermediate
Format: Live Human Online Webinar with Guided Labs
IDE Used: IntelliJ IDEA


Webinar Schedule (3 Hours)

Session 1: Understanding Errors and Exceptions

  • What exceptions are and why they exist

  • Compile-time vs runtime errors

  • Common Java exception types

  • Reading and understanding stack traces

Lab 1:

  • Trigger common Java exceptions intentionally

  • Read and interpret exception messages

  • Identify where and why failures occur


Session 2: Handling Exceptions Gracefully

  • Using try, catch, and finally

  • Handling invalid input and unexpected conditions

  • Preventing program crashes

  • Writing meaningful error messages

Lab 2:

  • Add exception handling to existing programs

  • Validate inputs and protect program flow

  • Keep applications running safely


Session 3: Debugging and Building Robust Java Programs

  • Debugging tools in IntelliJ IDEA

  • Setting breakpoints and stepping through code

  • Inspecting variables and program state

  • Improving reliability and readability

Lab 3:

  • Debug a multi-step Java program

  • Refactor code to improve robustness

  • Test edge cases and failure scenarios


Webinar Description

Java Webinar IV focuses on writing Java programs that are stable, predictable, and resilient. In this hands-on session, participants learn how Java handles errors, how to respond to failures gracefully, and how to debug programs effectively using professional tools.

Rather than avoiding errors, this webinar teaches how to understand, anticipate, and manage them. Labs are designed around realistic failure scenarios so learners can build confidence troubleshooting problems and improving program reliability.

All development and debugging is performed in IntelliJ IDEA, reinforcing workflows used in professional Java environments.


Lab & Exercise Structure

Each lab is:

  • Instructor-guided with live explanation

  • Based on real-world failure scenarios

  • Focused on understanding root causes

  • Built and debugged in IntelliJ IDEA

Lab code is reusable and serves as reference material for future Java projects.
