Usage

From source file:Main.java

public static byte[] load(InputStream is) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    byte[] buffer = new byte[1024];
    int len;//from   www .  j av a2s.  c om
    while ((len = is.read(buffer)) != -1)
        baos.write(buffer, 0, len);
    baos.close();
    is.close();
    return baos.toByteArray();
}
