How can I automatically generate Java POJO classes from complex JSON response? [closed]

I am integrating a REST API in a Java application, and the API returns a large JSON response.

Manually creating Java POJO classes with getters, setters, and mapping annotations becomes difficult and error-prone when the JSON structure contains nested objects and arrays.

For example, the API returns JSON similar to this:

{ "userId": 1, "name": "John", "address": { "city": "New York", "zip": "10001" }, "roles": ["ADMIN", "USER"] }

Normally I would create multiple Java classes and add annotations such as @JsonProperty or Gson mappings manually.

I would like to know:

Is there a way to automatically convert JSON into Java POJO classes?

Are there tools that generate getters, setters, and annotations automatically?

Can such tools support Jackson, Gson, or Lombok?

How do developers usually handle nested JSON structures efficiently?

Any workflow or tools would be helpful.
