Java Application Development with Agentic AI Foundations — Lesson 1: Java Application Architecture, Object Design, APIs, Persistence, and Testing

Learning Objectives

• Interpret how java application architecture, object design, apis, persistence, and testing changes application behaviour, data, accounting, or service delivery.
• Perform a repeatable sequence with known inputs, controls, outputs, and rollback points.
• Prove security, correctness, performance, recoverability, and support readiness.

Detailed Topics

• Java Application Architecture
• Object Design
• APIs
• Persistence
• Testing
• ownership, prerequisites, data, and acceptance criteria for java application architecture, object design, apis, persistence, and testing
• security, control, integration, performance, recovery, and support implications

Instructor Demonstration

Demonstrate java application architecture, object design, apis, persistence, and testing within a Java application enhanced with an AI agent that retrieves trusted context, invokes approved tools, and operates with measurable safety. Use representative data and capture Java unit tests, API responses so another practitioner can verify the result.

Hands-On Exercise

Complete a controlled Java Application Development with Agentic AI Foundations activity focused on java application architecture, object design, apis, persistence, and testing. Introduce a realistic case of weak application boundaries, isolate the cause, apply a reversible correction, and rerun the acceptance checks.

1. Record the requirement, environment, identities, dependencies, data, controls, and expected result.
2. Perform the workflow and capture course-specific evidence before and after each material change.
3. Test normal, boundary, failure, security, reconciliation, recovery, and operational conditions.
4. Document the root cause, correction, rollback, owner, support action, and next improvement priority.

Scenario Analysis

• Separate mandatory requirements from convenience requests and local workarounds.
• Compare the proposed approach against security, reliability, usability, cost, and audit expectations.
• Select the smallest supportable change and assign follow-up ownership.

Troubleshooting Guidance

When java application architecture, object design, apis, persistence, and testing does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review the most relevant Java unit tests, API responses before editing configuration. Test one reversible hypothesis at a time, verify recovery, and confirm that the fix does not create weak application boundaries elsewhere.

Validation Checklist

• Prerequisites, ownership, data context, settings, and expected outcomes are documented.
• The result is reproducible and supported by Java unit tests, API responses.
• Security, controls, data quality, integration, performance, recovery, and support conditions are reviewed.
• Exceptions, corrective action, rollback, approvals, monitoring, and handover are recorded.

Lesson Outcome

Learners can apply Java Application Architecture, Object Design, APIs, Persistence, and Testing in a realistic Java Application Development with Agentic AI Foundations situation and defend the result with course-specific evidence.
