Write a String to ByteArrayOutputStream

[Sara Tracy]

Hi,

I know how to read data from a ServletInputStream (or a FileInputStream) and write it to ByteArrayOutputStream.
Example:

           
ServletInputStream sis = request.getInputStream();
// or InputStream sis  = new FileInputStream("ABC.txt");
byte[] buffer = new byte[4000];
ByteArrayOutputStream baos = new ByteArrayOutputStream(4000);
int bytesread = 0;
                                              
while(true)
{
        bytesread = sis.read(buffer);
        if (bytesread == -1)
             break;
        baos.write(buffer,0,bytesread);
}

However, I would like to read a String in an InputStream and write it to a ByteArrayOutputStream ? For example:
String data = "<?xml version=\"1.0\"?>";
How do I do that ?

thanks
Sara

Well, if you want to read a String from the InputStream then, wrap the InputStream into a BufferedReader.

You can somewhat like this:

InputStream in = request.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
String line = null;
while( (line = reader.readLine())!=null){
  //do something with your string
}

Now, if you want to write your String into a ByteArrayOutputStream or any other kind of OutputStream you could simple use the String.getBytes() method.

For instance;

byteOutput.write(line.getBytes());

I hope this helps!
