Comment utiliser : JSON to Java
- Paste a JSON sample in the input — Java is already selected.
- Set the root type name and options such as optional fields and date detection.
- Copy the generated Java code into your project.
JSON to Java classes
Each JSON object becomes a Java class (or record) with typed fields; nested objects become their own classes and arrays become List<T>. Keys that aren’t valid Java identifiers are mapped with annotations, so the class works with Jackson (@JsonProperty) and Gson (@SerializedName).
Reading the JSON
With Jackson: new ObjectMapper().readValue(json, Root.class). Configure FAIL_ON_UNKNOWN_PROPERTIES to decide whether extra fields should be ignored. Whole numbers that may exceed 2³¹ are typed as long.
Private by design
The conversion runs entirely in your browser — API responses with customer or internal data are never uploaded.
