Walkthrough

A new chat application feature is introduced to replace the existing HelloFX "Hello MVC" placeholder. The implementation includes a JavaFX controller and FXML view for the UI, a ChatModel class for handling message transmission via HTTP and server-sent events (SSE) over ntfy, updated build configuration to support Java 25, and corresponding test coverage.

Changes

Cohort / File(s)	Change Summary
Build & Module Configuration pom.xml, src/main/java/module-info.java	Added maven-compiler-plugin with Java 25 source/target, maven-surefire-plugin with test configuration, and module dependency for java.net.http to enable HTTP client support.
Chat Business Logic src/main/java/com/example/ChatModel.java	New class implementing message sending via HTTP POST to ntfy topic and subscription to server-sent events with message parsing, deduplication, and thread-safe UI dispatch.
Chat UI Layer src/main/java/com/example/ChatController.java, src/main/resources/com/example/chat-view.fxml	New JavaFX controller and FXML file defining chat interface with ListView for messages, TextField for input, and integration with ChatModel for message flow.
Application Entry Point src/main/java/com/example/HelloFX.java	Updated resource loading from hello-view.fxml to chat-view.fxml and window title from "Hello MVC" to "Chat App".
Test Coverage src/test/java/com/example/ChatModelTest.java	New test suite validating ChatModel parsing, HTTP message sending, and SSE subscription behavior.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

• ChatModel.java requires careful review of HTTP/SSE handling logic, message parsing with regex, thread-safety patterns, and deduplication mechanism.
• ChatController.java integration with ChatModel and Platform.runLater usage for UI thread safety.
• pom.xml verification that Java 25 target is appropriate and maven-surefire-plugin configuration is correct.
• Test coverage for ChatModel mocking strategies and SSE stream simulation should be validated for correctness.

Poem

🐰 A chat app hops into view,
With ntfy and SSE so new,
Messages flow both to and fro,
On Java 25's runway go!
Platform.runLater keeps UI true—
Hop hop! ✨
