Hi, I have heard of Sun Microsystems Java OS but never used it. I would like to try it out and I think a few other people would too! If anyone has it could they please upload it or whatever you do! (I'm a new member)
One of the issues with Java is that it is a pretty slow. From what I've learned from past experience, since Java is not a binary language, it has to be compiled every time a program is run using a "Virtual Machine". Sun did make an OS in Java but it was very short lived due to many issues including the speed of the OS. However, I had an old cellphone back in the early 2000's which used Java. However Java was only used in this case for applications.
