Java

An FFM (Panama) wrapper over the C ABI. Construct a Shazam from a JSON spec, then drive it with command(json) -> json — index first, then match.

        String spec = """
            {"features":[{"kind":"price","field":"close"}],
             "window":10,"metric":"euclid"}""";

        try (Shazam shazam = new Shazam(spec)) {
            shazam.command("{\"cmd\":\"index\",\"history\":[]}");
            String response = shazam.command("{\"cmd\":\"match\",\"current\":[],\"k\":5}");
            System.out.println("wickra-shazam " + Shazam.version());
            System.out.println(response);
        }
    }
}

The binding uses the Java Foreign Function & Memory API, so it needs JDK 22+ and --enable-native-access.
