create an ArrayList of bytes

Question

I want to read bytes from a wave file into an array. Since the number of bytes read depends upon the size of the wave file, I\'m creating a byte array with a maximum size of

Answer 1

ArrayList isn't the solution, ByteArrayOutputStream is the solution. Create a ByteArrayOutputStream write your bytes to it, and then invoke toByteArray() to get the bytes.

Example of what your code should look like:

in = new BufferedInputStream(inputStream, 1024*32);
ByteArrayOutputStream out = new ByteArrayOutputStream();
byte[] dataBuffer = new byte[1024 * 16];
int size = 0;
while ((size = in.read(dataBuffer)) != -1) {
    out.write(dataBuffer, 0, size);
}
byte[] bytes = out.toByteArray();
