Writes the complete contents of this ByteArrayOutputStream to the specified output stream argument, as if by calling the output stream's write method using out.write(buf, 0, count) .

Usage

From source file:Main.java

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

    byte[] bs = { 65, 66, 67, 68, 69, 70, 71, 72 };

    OutputStream os = new ByteArrayOutputStream();

    ByteArrayOutputStream baos = new ByteArrayOutputStream();

    baos.write(bs);/*w  w  w. ja  v  a  2s. c  om*/

    baos.writeTo(os);

    System.out.println(os.toString());

}

From source file:Main.java

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

    byte[] bs = { 65, 66, 67, 68, 69, 70, 71, 72 };

    OutputStream os = new ByteArrayOutputStream();

    ByteArrayOutputStream baos = new ByteArrayOutputStream(200);

    baos.write(bs);//from  w ww  .  ja  va 2 s . c  o  m

    baos.writeTo(os);

    System.out.println(os.toString());

}

From source file:Main.java

    for (int i = 0; i <= 20; i++) {
