Am not a "tekkie" and wouldn't want to steer you wrong. Don't use Java but checked in the app market and looks like there are several java apps that are available for download. It does not come with installed. I hope this helps.
I don't think there's support for java. I'm unable to login to my internet banking because java RE is required. I've tried apps like photon browser with no luck. Apparently java is in a legal battle with Google and therefore the Samsung tabs with android are negatively affected.
