Vlumondoxasaid: I don't use it, neither have I Java on my computer. The Java client contains a stand-alone version of Java so you can play it without having Java itself installed on your computer. Only if you want to play in your browser window do you need Java installed.
Wait, Internet Explorer still exists? I thought that piece of crap was gone after recycling it into the equally bad Microsoft Edge and recycling the logo. Yes, it still exists and I'm sure you have it on your computer too if you actually look for it Unless you're using mac or linux of course.
