What is binary for you? What do you want to do with the value after? — Alexandre Lavoie, Jun 12 '13 at 06:51
In what form do you want that binary representation? A ByteBuffe? A String of 1's and 0's? — Michael Lawrie, Jun 12 '13 at 06:51

Try this,

byte[] infoBin = null;
    infoBin = "Java".getBytes("UTF-8");
    for (byte b : infoBin) {
        System.out.println("c:" + (char) b + "-> "
                + Integer.toBinaryString(b));
    }

Try this

  byte[] bytes = str.getBytes(charSetName);

this encodes str into a sequence of bytes using the named charset, storing the result into a byte array.
