Usage

From source file:Main.java

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

    byte[] bs = { 65, 66, 67, 68, 69 };
    ByteArrayOutputStream baos = new ByteArrayOutputStream();

    // write byte array to the output stream
    baos.write(bs, 3, 2);

    // read all the bytes in the output stream
    for (byte b : baos.toByteArray()) {
        System.out.println(b);//from  www . ja  v  a 2  s.c o  m
    }

}
