JsonToJava jsonToJava = new JsonToJava();
//jackson annotations is generated by default. use jsonToJava.jsonToJava(complexJson, "MyJsonToJavaObject", "org.example.jsontojava", "jsontojava/output", false) to generate class without annotations.
jsonToJava.jsonToJava(complexJson, "MyJsonToJavaObject", "org.example.jsontojava", "jsontojava/output");

// MyJsonToJavaObject.java will be generated in jsontojava/output.

Only .json and .txt files supported as json input file.

String pathToJsonFile = "input/MyJsonToJavaObject.json";
JsonToJava jsonToJava = new JsonToJava();
//jackson annotations is generated by default. use jsonToJava.jsonToJava(pathToJsonFile, "MyJsonToJavaObject", "org.example.jsontojava", false) to generate class without annotations.

List<JsonClassResult> jsonResult = jsonToJava.jsonToJava(pathToJsonFile, "MyJsonToJavaObject", "org.example.jsontojava");
