I'm a little confused over java. I wanted to download an app from sourceforge (which made me nervous as I've never used that site before. Is it safe?) But in order to run it I need "java runtime enviroment" (is THAT safe?) To do that I need to download Java 8 update 111. I tried checking which java I had on one of those websites, but I told me that "browser has java disabled". What does that mean? Am I running without java? And can I download Java 8 update 111 without any worry?
