Usage

From source file:Main.java

public static void main(String[] args) throws Exception {

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    BufferedOutputStream bos = new BufferedOutputStream(baos);

    byte[] bytes = { 1, 2, 3, 4, 5 };

    bos.write(bytes, 0, 5);

    bos.flush();/*from   ww w .ja  v a2  s .  c  o  m*/

    for (byte b : baos.toByteArray()) {
        System.out.print(b);
    }
