Document

Creates a ByteArrayInputStream so that it uses buf as its buffer array.

Usage

From source file:Main.java

public static void main(String[] args) {
    byte[] arrByte = new byte[1024];
    byte[] byteArray = new byte[] { 'j', 'a', 'v', 'a', '2', 's', '.', 'c', 'o', 'm' };

    try {/*from www .  j  a va 2 s  .co m*/
        InputStream is = new ByteArrayInputStream(byteArray);
        PushbackInputStream pis = new PushbackInputStream(is);

        System.out.println(pis.available());

        for (int i = 0; i < byteArray.length; i++) {

            arrByte[i] = (byte) pis.read();

            System.out.println((char) arrByte[i]);
        }

    } catch (Exception ex) {
        ex.printStackTrace();
    }
}
