Just a few short years ago, Java was one of the most popular media used for games, webpage scripts etc. It was very straightforward to use and it had the ability to create useful scripts that worked well on almost all websites. If you remember, security experts found some really nasty flaws in the code. Instead of actually fixing the code, Oracle decided to just block almost all java code whether it was a problem or not as a workaround. This created a huge mess for many developers who were using Java on their WebPages.
