Yeah not sure what the problem is. Google "download java" and this is the first link.

This gives you a download of the JRE (the runtime components), not the JDK (the developer components). So if you're an end user of Java with no desire to compile your own Java projects, the java.com site will give you what you need.

Note also, java.com will only give you the latest short-term support version, which is currently Java 12. So if you want a LTS version, you will have to go elsewhere.
