Creating JSON using java library

I am trying to create a JSON as following format - 

{
 "approvable" : "true",
 "approvedBy" : [user1, user2, user3, user4]
}

I have two java variables - 

boolean approvable;
List<User> approvedBy;

If the approvedBy list contains all the Users, then can I make the JSON directly using any JSON library? Suppose I want to do something like this -

JsonBuilder jb = new JsonBuilder();
jb.add("approvable", true);
jb.add("approvedBy", approvedBy);

Ultimately, all I need to do is to simplifying the making of JSON. Can anyone suggest any good JSON library which give me this support?

Thanks in advance

API used is flexjson

public static void main(String args[]) throws Exception {

        Child child2 = new Child("ankur", 23);
        Child child1 = new Child("ankurs", 23);
        Child child3 = new Child("ankurss", 21);

        List<Child> childList = new ArrayList<Child>();
        childList.add(child1);
        childList.add(child2);
        childList.add(child3);

        Parent parent = new Parent();
        parent.setApprovable(true);
        parent.setChildList(childList);
        JSONSerializer serializer = new JSONSerializer();
        System.out.println(serializer.exclude("*.class").deepSerialize(parent));

    }

Output

{
    "approvable": true,
    "childList": [
        {
            "age": 23,
            "name": "ankurs"
        },
        {
            "age": 23,
            "name": "ankur"
        },
        {
            "age": 21,
            "name": "ankurss"
        }
    ]
}
