Record Class StaticFileResponse

java.lang.Object
java.lang.Record
net.jrodolfo.java_evolution.java18.simple_web_server.StaticFileResponse
Record Components:
statusCode - the HTTP status code
body - the response body
public record StaticFileResponse(int statusCode, String body) extends Record
Represents a response returned by the local static-file server example.

The Java 18 feature is about serving static files quickly. This record keeps the client-side verification small so tests can assert the HTTP status and response body without exposing learners to a full web framework.
