Examples of java.io.PushbackInputStream.unread()

java.io.PushbackInputStream.unread()
Pushes back a byte by copying it to the front of the pushback buffer. After this method returns, the next byte to be read will have the value (byte)b. @param b the int value whose low-order byte is to be pushed back. @exception IOException If there is not enough room in the pushbackbuffer for the byte, or this input stream has been closed by invoking its {@link #close()} method.

            PushbackInputStream pin = 
                new PushbackInputStream(connection.getInputStream());
            int c = pin.read();
            if (c != -1) {
                pin.unread((byte)c);
                in = pin;

        } catch (IOException ioe) {
