Adding a Suspect to the Model Layer

Next, return to Crime.java and add a new JSON constant and a member variable to give Crime a field that will hold the name of a suspect. Also, modify the JSON methods to serialize the suspect into and out of JSON code and add new accessor methods.

Listing 21.2  Adding suspect field (Crime.java)

public class Crime {
    ...
    private static final String JSON_PHOTO = "photo";
    private static final String JSON_SUSPECT = "suspect";

    ...
    private Photo mPhoto;
    private String mSuspect;

    public Crime(JSONObject json) throws JSONException {
        mId = UUID.fromString(json.getString(JSON_ID));
        ...
        if (json.has(JSON_PHOTO))
            mPhoto = new Photo(json.getJSONObject(JSON_PHOTO));
        if (json.has(JSON_SUSPECT))
            mSuspect = json.getString(JSON_SUSPECT); ...
