DEMO

String original = "{\n" +
        "  \"baz\": \"qux\",\n" +
        "  \"foo\": \"bar\"\n" +
        "}";

String patch = "[\n" +
        "  { \"op\": \"replace\", \"path\": \"/baz\", \"value\": \"boo\" },\n" +
        "  { \"op\": \"add\", \"path\": \"/hello\", \"value\": [\"world\"] },\n" +
        "  { \"op\": \"remove\", \"path\": \"/foo\" }\n" +
        "]";

String result = JSONPatch.apply(original, patch);
assertEquals("{\"baz\":\"boo\",\"hello\":[\"world\"]}", result);
