  • Which one of the following is NOT a pitfall of inheritance?

    - by Difficult PEOPLE
    Which one of the following is NOT a pitfall of inheritance? Base-derive classes should be totally separate and do not have an is-a relationship. Base-derive classes should have been aggregate classes instead. Inheritance may be inverted, example: Truck<-Vehicle should be Vehicle<-Truck. Incompatible class hierarchies may be connected because of multiple inheritance. Aggregation should have been used instead. Functionality is transferred from a base class to a derived one. In my opinion, NOT a pitfall of inheritance meas can use inheritance. 1 seems do without inheritance 2 aggregate substitute Base-derive I don't know So, I think 5 is the answer.

  • resultCode is always 0

    - by Aaron T
    I'm trying to get the resultCode to be OK inside my onActivityResult function. However, it keeps coming back as 0. I have spent several days on this, and can't figure out why it doesn't work. Here's my code. If anybody can help me, I'll be very grateful, Thanks. My Activity1 class: private class MyTask extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... urls) { // process return result; } @Override protected void onPostExecute(String result) { Intent i = new Intent(Activity1.this, Activity2.class); i.putExtra("Value1", "This value one for ActivityOne "); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivityForResult(i, REQUEST_CODE); textView.setText(result); } } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == RESULT_OK && requestCode == REQUEST_CODE) { // do something } } My Activity 2 class: @Override public void finish() { Intent data = new Intent(); data.putExtra("returnKey1", "return 1"); setResult(RESULT_OK, data); super.finish(); } My manifest: <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".Activity1" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".Activity2" android:label="@string/app_dialog_name" android:launchMode="singleTop" android:excludeFromRecents="true" android:taskAffinity="" android:theme="@android:style/Theme.Dialog"> </activity> </application>

  • regarding object recycling

    - by ajaycv
    I have a question. What is wrong with regards to the below code: ArrayList tempList2 = new ArrayList(); tempList2 = getXYZ(tempList1, tempList2); //method getXYZ getXYZ(ArrayList tempList1, ArrayList tempList2) { //does some logic and adds objects into tempList2 return tempList2; } The code will get executed but it seems by passing tempList2 to the getXYZ method argument, it is doing object recycling. My question is, Is recycling the tempList2 arraylist object correct?

  • Cocoa (Touch) for Swing Developers #1: Where Are the Layouts?

    - by yar
    My iPhone SDK and Objective-C learning is moving ahead quickly, thanks to several great books and online help (including this one). But I do have some basic questions due to what I already know that will be answered eventually, but I'd rather get a heads-up now if possible :) Are there equivalents for LayoutManagers in Cocoa Touch? Are they used, or is absolute positioning used instead? I have seen some of the layout stuff in IB, but I'm not sure what to look at in code. Aside from using the IB, are UIControls added directly to UIView instances using the addSubview (like add in Swing)? These are just two concrete questions that I've thought of just now, but I would love to see any translation of Swing concepts to Cocoa Touch.

  • Searching major search engines with text such as <%#

    - by Daniel Dyson
    If I type '<%# vs <%"' into any of the major search engines, everything is stripped out except the 'vs'. I understand why they do this. I would just like to know if anyone knows of a way to escape illegal characters so that they are searched properly. I know this is not strictly a programming question, but it is relevant.

  • Removing a character from JSONObject?

    - by RandomlyKnighted
    My JSONObject has some random characters contained within the string so I'm trying to remove them. I've tried this but with no luck. String result = s.substring(1, s.length() - 2); JSONObject json_data = new JSONObject(result); if (json_data.has("[")) { json_data.remove("["); } if (json_data.has("]")) { json_data.remove("]"); } if (json_data.has(",")) { json_data.remove(","); } It's still not removing the characters from the JSONObject. Am I checking the JSONObject for the characters incorrectly?

  • Solr authentication possible? (or apache port authentication would also work)

    - by Camran
    Currently anybody can access the solr admin page by going to my_ip:8983/solr I can't have it like that, so how can I make it prompt for password or something? I have setup my servers apache2.conf file to prompt for password whenever my site is accessed by www.mydomain.com. But when using another port, the "require password" wont show up. Any ideas how to secure this? Don't point me to the SolrSecurity wiki because it's simply too outdated. I have tried it without luck. Thanks
