Right now i am encrypting and decrypting information using RSA algorithm and generating public and private key from
But i dont know how to use certificate in code to encrypt and decrypt data. I have generated certificate using keytool.

You don't need a certificate for en/decryption, you need just the key. The Java API for this is called JCE, and you can find more information about it, including links to code samples, at

you can make use of this command below . this requires itext.jar
CertificateFactory cf = CertificateFactory.getInstance("X509"); Collection col = cf.generateCertificates(new FileInputStream("export.cer"));
It is sorta covered in the
