This article covers installation of Java in Windows and Linux machines. Though Installation of Java is very simple and often PCs ship with JRE, it would still help absolute new beginners to have a reference article to install Java before starting on the learning path. This article covers installation of Java 15 (latest at the time of writing this article) on Windows 10. The installation process does not differ much for other Windows variants and can be used as is.
Though PCs often ship with JRE, its not sufficient to start developing Java programs as it lacks the Java Development Kit which comes with its own arsenal of tools and libraries. To install JDK SE 15, first download the JDK executable from Oracle Site.
