JDK Installation

Before it's past the point of no return get a kick out of the chance to state that on the off chance that you can't answer the question "What is JDK?", you likely better begin from Java SE and put off Java EE stuff.

Which JDK to pick? It has been noticed that most engineers lean toward Oracle JDK over OpenJDK, however one can't give hard confirmation why it's better, by and large they're essentially the same. So it's one's decision which one to utilize.

Oracle JDK Installation

OpenJDK Installation

To install OpenJDK 7 execute the command in terminal:
sudo apt-get install openjdk-7-jdk

To check if openJDK was installed fine execute following command:
java -version
If everything is good you will see something like
java version "1.7.0_25"

OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.12.04.2)

OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
If installation finished without errors, but a different version of JVM is shown, after installing other tools open this simple guide to change it to openjdk-7 version.

Note:

If you are not using Ubuntu, and you don't know who are sudoers, please execute commands here as super user (root). For this type `su -` in terminal, and input root's password, you should know it. When you are done here please don't use that terminal, just close it. As super user you can skip typing sudo.
