Do not download binaries straight from the Internet. That is not how to install software on Linux. It is how Windows users do it, but it is wrong on Linux.
Install it from the package manager. Google for instructions for your version, since you did not bother to tell us what you are running. Without detailed specific info we can't help you.

Java is a write once, run anywhere language, meaning you don't need anything special other than the JDK and a Linux compatible IDE.
For the JDK you can either use OpenJDK (An opensource implementation of Java / JDK) or Oracle's JDK (Original and most used JDK). OpenJDK is easily available through sources like Ubuntu's Software Centre whereas Oracle's JDK is a bit more painful to install (Depending on the distro), but this is a great resource to make it easier (For Debian based systems like Ubuntu).
As for an IDE you're already on the right track. Both Eclipse and IntelliJ are great options and have cross-platform support.
