How do I programmatically import a public key .cer file into a java keystore using JSSE?

I want to take a public key .cer file generated from java keytool command like this:

"keytool -export -alias privatekey -file publickey.cer -keystore privateKeys.store"

and import it into a new, empty java keystore like this:

"keytool -import -alias publiccert -file publickey.cer -keystore publicCerts.store"

except I want to do the import programmatically, using JSSE.

Stack Overlords, work your magic! Thanks!
