Java kindly help me if anyone has a code

Why would you want DES or RC4? Surely AES would be a better choice. In Java, you could use the Java Cryptography Extension, which has AES (in addition to DES and maybe even RC4).
There's source for AES at http://www.rmcis.com/encryption/index.html that runs on all JVMs since 1.1.
Wei Dai's Crypto++ is a C++ library at http://www.cryptopp.com/ that I'm pretty sure has source for AES.
