Java IO Tutorial - Java PushbackInputStream .read (byte[] b, int off, int len)

Syntax[] b, int off, int len) has the following syntax.

public int read(byte[] b, int off, int len)  throws IOException


In the following code shows how to use[] b, int off, int len) method.

/*www .  j  a  v  a2s  .com*/
public class Main {

   public static void main(String[] args) {

      byte[] arrByte = new byte[1024];

      byte[] byteArray = new byte[]{'j', 'a', 'v', 'a', '2','s','.','c','o','m'};

      // create object of PushbackInputStream class for specified stream
      InputStream is = new ByteArrayInputStream(byteArray);
      PushbackInputStream pis = new PushbackInputStream(is);

      try {

         // read a char into our array, 0, 3);

         // print arrByte
         for (int i = 0; i < 3; i++) {
            System.out.println((char) arrByte[i]);

      } catch (Exception ex) {

The code above generates the following result.
