JRE (Java Runtime) is needed for running Java programs. Still – You should keep in mind that screenshots and versions might vary little bit, but most of the time process of installing remains same. I will try my level best to update this document as and when required. At the time of writing this article – it does talks about the latest version of Java JDK, which might not be same at the time you are reading this document and installing Java JDK. IMPORTANT : This tutorial is just to help you learn how to install Java JDK/Java SE on your own. The JDK or Java Development Kit can be freely downloaded from official website of Sun Microsystems which is now very much the part of Oracle. JDK is also known as “Java Platform, Standard Edition” or simply Java SE.
