Display sound data value from ByteArrayOutputStream

[cielle]

hi People,

Can advise what is the function that i can use to retrieve or display the data that i stored in ByteArrayoutputStream buffer?

So far i can only store the data in... but how can i retrieve and display them on output panel?

Many Thanks

Code below might be of any help to you:

import java.io.ByteArrayOutputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;

public class DateDifference
{
	public static void main(String[] args) throws IOException {
		ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
		String s = "Put this string in ByteArrayOutputStream";
		byte buf[] = s.getBytes();
		// write the bytes in ByteArrayOutputStream 
		byteArrayOutputStream.write(buf);
		
		// Call for printing contents
		printStreamContents(byteArrayOutputStream);
		
		// write the contents to file
		writeToFile(byteArrayOutputStream);
	}
	
	private static void printStreamContents(ByteArrayOutputStream baos){
		
		// printing the contents
		System.out.println("ByteArrayOutputStream contents: " + baos.toString());
	}
	
	private static void writeToFile(ByteArrayOutputStream baos) throws IOException{
		
		OutputStream outputStream = new FileOutputStream("example.txt");
		baos.writeTo(outputStream);
		outputStream.close();
		
	}
}

Thank you for your reply. I have tried with .toString method. But stilll ... Can advise on below?

Below is my scenario:
I wish to display the sound data value (numeric) at the output panel while i am capturing sound from my microphone.
The program is included with the playback features which is not included in this topic.

For this purpose, i have a temporary buffer to store the captured sound data temporary from audio dataline.

class CaptureThread extends Thread{
byte tempBuffer[] = new byte[10000];

public void run(){
byteArrayOutputStream = new ByteArrayOutputStream();

//Read data from the internal buffer of the data line.
int cnt = targetDataLine.read(tempBuffer, 0, tempBuffer.length);

if(cnt > 0){
//Save data in output stream object.
byteArrayOutputStream.write(tempBuffer, 0, cnt);
System.out.println(byteArrayOutputStream.toString());
}//end if

byteArrayOutputStream.close();
}

The result that i got is a bunch of unknown character displayed on the output panel. I have gon through the method description for byteArrayOutputStream.toString(). ByteArrayOutputStream (Java 2 Platform SE v1.4.2)
Suppose it shows the content of buffer.

The purpose i wish to display the content because i wish to find out the way to retrieve the sound data for Fast Fourier transform.

Like MATLAB, the sampled sound data (x) can be display with such function
[x,fs,nb]=wavread("My_love.wav");

Hereby wish to have your advise how can i get do the same thing of displaying the sound data value with Java.

Please advise. Many thanks on correcting my mistake.
