How to write java code for To_bytes function of Teradata

I cam across a situation where, I have to write a java code for the teradata function called To_Bytes. I have to write the function which will works exactly same as To_Bytes in tera data.

From teradata doc.

To_Bytes 

Decodes a sequence of characters in a given encoding into a sequence of bits. The following encodings are supported:

• BaseX • BaseY • Base64M (MIME) • ASCII

where X is a power of 2 (for example, 2, 8, 16) and Y is not a power of 2 (for example, 10 and 36).

Example_1,

SELECT TO_BYTES ('5A', 'base16'); 

returns '01011010'

Example_2,

SELECT TO_BYTES ('-22EEVX', 'base36'); 

returns '111 1000 1000 1101 0011 0011 0010 0011'

If anyone of you has any idea how to do that, please share , appreciate a lot.

You can start with smth like (not a complete solution, just a kick in the possible direction):

String s = "ROGER"; byte[] bytes = s.getBytes();  for (int i=0;i<bytes.length;i++) {   System.out.println(Integer.toBinaryString(0x100 + bytes[i]).substring(1)); }
