Java automatically tells you when new updates are available.
If you want to manually download updates and new versions, you should only get them from the official Java website.
You should also remove older versions of Java.
Downloading from other sites and using old versions of Java can leave your PC open to infection.
Java SE 6 is only be updated if you are an enterprise customer. If you are running Java SE 6, this might leave you vulnerable to threats. We recommend you either upgrade your Java version to 7 or higher and remove Java 6, or completely remove Java from your PC.
