Is there any console that supports Java on their Internet browser? [closed]

Solution 1:

There is no current gen, or previous gen consoles which will do this without modification of some sort.

It's possible if you have the right model of PS3 you could install Linux on it, and do it via this, but other than that you won't have any luck I'm afraid :(

Solution 2:

When the HTML5 beta was still available, it was possible to play RS3 on the Wii U's browser. It lagged like hell, but worked.

Right now, however, it's impossible to get RuneScape to run on consoles without modding them, as none of them have Java installed.
