JDK installation guide

First of all you will need to download the JDK(Java Development Kit) according to your operating system. Visit the official oracle website url: and choose the jdk according to your Operating System. For the windows users the installation process is pretty much state forward. Just double clicking on the jdk file you have downloaded from the url mentioned above and then clicking next, next... will do that. For Linux user there are many ways to install JDK but I will proceed through Terminal: The whole installation process can be done by running just two commands. Open terminal (ctrl Alt T) and run the following command. 1. Add the PPA (Personal Package Archives): sudo add-apt-repository ppa:webupd8team/java 2. Install the JDK: run the following command to install jdk: sudo apt install oracle-java8-installer When the command complete then just type javac -version to see the java compiler version. Thank you.
