Error Handling with Android JSON Exception

Question

I get this this nice message when the companyTwo value in my datastore is blank:

09-09 15:13:52.927: W/System.err(31091): org.json.JSONException: No value for companyTwo

What would be a good way to handle this assuming I can only pull from the datastore instead of post a filler value?

private static final String TAG_COMPANY ="company";
private static final String TAG_OTHERCOMPANY ="companyTwo";


String company1 = jsonObj1.getString(TAG_COMPANY);
String othercompany1 = jsonObj1.getString(TAG_OTHERCOMPANY);

@Hi-TechKitKatAndroid The JSON item companyTwo is in some contacts and missing in others. So it will work fine if companyTwo is in the JSON, but if not I get the JSON error. I have no way of telling if an entry will have the value of companyTwo or not. — johnsonjp34

JSON only supports trying and then catching if you use get function — Mohit

@Hi-TechKitKatAndroid I used the opt function. Works good. Thanks! — johnsonjp34

try
{
String company1 = jsonObj1.getString(TAG_COMPANY);
}
catch(Exception ex)
{
// do whatever you want
}

alternatively you can do this

String company1 = String.valueOf(jsonObj1.optString(TAG_COMPANY));
