I know my Windows 8.1 computer didn't come with java. I have been running in to some problems online because of that. I can't use Tumblr with out java, and there are some sites where you can download videos from You Tube that require java that I can't even use that I always used just fine on my other computer. I tried to make a Tumblr account, and it wouldn't let me because it requires java. So I wonder if it is possible to download java on my Windows 8.1 lap top computer?
