Details

Save as Main.java, compile with javac Main.java, and run java Main. Uses the Java 21 standard library. Use URI parsing instead of splitting a URL at punctuation manually.

Test inputs, results and environment

The exact published code ran in a dedicated Linux test container with prepared inputs. Unprivileged snippet process, external networking disabled, read-only root filesystem, and a fresh temporary working directory. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
