java - Simple iterator looping gives unexpected result -


I'm sure this is a clear error with my argument, but I guess what I'm doing is wrong work Has been doing. I just have an array list of security codes, I want to count the relations between each combination of security code. My code is as follows: 

  Private zero crossCorr (ArrayList & quot; string> code, HashMap & lt; string, stock & gt; stockMap) {// via code list Iterates and all cross-correlation: Iterator is

I get output -

----- GOOG - GOOG - GOOG - correlation is 1.0000000000000002

but I never get it

YHOO is - GOOG - is the correlation .... etc etc

I am sure this is a simple error and for some reason I am not picking it up.

I know that I am doing the calculation of correlation twice, I will fix it when I want to work this part.

Please tell me that I need to provide more information.

A quick test application has removed the code references that we know is not working for me is.

Is it possible that you dally not be an unsolicited exception? If you can post a short but full program that demonstrates the problem, copy your whole project to be extremely helpful and just remove the bits (like hard-coding data and return value) when Until you remove the problem, you can not take anything else. At that time you may well get the problem for yourself.

By the way, if you are using Java 1.5 or greater, then obviously an iterator for the extended use for the loop. You will do this: 

 For  (string code 1: code) {// ... (string code 2: code) {// ...}}

qt - How to prevent QAudioInput from automatically boosting the master volume to 100%? -

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName ().
