Can someone give me exact directions on how to update java for google chrome?

Firefox is easy, I just have to update link to point to the new location, but I can't figure out how to get it to update on chrome.

If it helps you any, I play games on a site called pogo.com and if java is up to date my pop up windows will open, hang a few minutes and come back with an java error message that tells me I need to update java for the site to function properly.
