JSON to Java POJO

A POJO (Plain Old Java Object) is a simple class with private fields and public getters/setters. This generator infers types from your JSON: boolean for booleans, int/double for numbers, String for strings, List<T> for arrays, and a nested class for objects. For similar tools see JSON to Go struct and JSON to Rust struct.
