String's Maximum length in Java - calling length() method -


My question is very basic, but I did not find any answer on Google search.

Java , length () method call

> I know that length () as a string as char [] ;

class = "post-text" itemprop = "text">

Considering the method of class one int , the maximum length to be returned by the method, which is 2 ^ 31 - 1 (or approximately 2 billion.)

In terms of the length and sequencing of arrays , (E.g. char [] , which is probably the way internal data representation has been applied to string s), says that:

The variable present in an array has no name; Instead, those array references are used by expressions that use the non-integer integer index values. These variables are called the component of the array. If an array contains the n component, then we say that n of the array Length is ; Elements of the array are referred to by using the integer index from 0 to n - 1 , inclusive.

In addition, indexing should be according to int values, as outlined below:

Code> int values ​​should be indexed by;

Therefore, it seems that the limit is actually 2 ^ 31 - 1 , because it is a non-primary int The maximum value is.

However, there are probably other limitations, such as the maximum allocated size for the array.

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 ().
