Lab 2:

  • Store custom objects in collections

  • Perform searches and simple filters

  • Display summarized results

Session 3: Modeling Real-World Scenarios

  • Combining objects, methods, and collections

  • Organizing application data logically

  • Building reusable data-handling patterns

  • Preparing for larger applications

Webinar Description

Java Webinar III focuses on handling groups of data and modeling real-world scenarios using Java collections. In this hands-on webinar, participants learn how Java manages lists of objects, how data is processed efficiently, and how collections support real application logic.

Rather than working with isolated variables, this session emphasizes data-driven programming. Labs demonstrate how objects and collections work together to represent meaningful information such as users, records, or transactions.

All coding is completed in IntelliJ IDEA, reinforcing professional development workflows and debugging practices.

Lab & Exercise Structure

Each lab is:

  • Instructor-guided with live explanation

  • Practical and incremental

  • Focused on realistic data handling

  • Built and executed in IntelliJ IDEA

Lab code serves as reusable reference material for future projects.
