How to use Google/GSON to convert a JSON string into Java POJO?

Question

I have the following string:

{"account":{
    "username":"ikevin2222",
    "birthdate":"2017-01-31T09:37:44.000Z",
    "gender":true,
    "emailaddresses": [{
        "emailaddress":"aaa@bbb.com",
        "verificationcode":"AAAAAA",
        "isverified":false
    }]
}}

How do I use Google/GSON to convert it to Java POJO?

Have you tried this : `gson.fromJson(jsonString, MyClass.class)`? — Abubakkar, Jan 31 '17 at 09:43
Write a POJO corresponding to your JSON structure and invoke the method as specified by @Abubakkar in his comment — Shubham Chaurasia, Jan 31 '17 at 09:48
The "account" was causing some confusion, but it's been resolved. Thanks! — ikevin8me, Jan 31 '17 at 10:37

Generate your POJO by using http://www.jsonschema2pojo.org/ or by adding plugin in studio (https://github.com/Hexara/Json2Pojo)

now add dependencies compile 'com.google.code.gson:gson:2.6.2':

convert your json or string to POJO

Gson gson = new Gson();
POJOClass pojo = gson.fromJson(jsonObject.toString(), new TypeToken<POJOClass>() {}.getType());
