What is Java and why do you need it?
Before we dive into the installation process, let's first understand what Java is and why you may need it on your Windows Server 2019.
Java is a programming language and a platform
Java is both a programming language and a platform. As a programming language, Java allows developers to write code that can run on any device or platform that supports Java. As a platform, Java provides a set of libraries and tools that enable developers to create and run applications that use Java.
Java enables you to run applications on different devices and platforms
One of the main advantages of Java is its portability. This means that you can write a Java application once and run it on any device or platform that has a Java Runtime Environment (JRE) installed. The JRE is a software component that provides the basic functionality for running Java applications. It includes a Java Virtual Machine (JVM), which is responsible for executing the Java code, and a set of core libraries, which provide common features and functions for the applications.
Java is required for some web applications and software development tools
Another reason why you may need Java on your Windows Server 2019 is that some web applications and software development tools require it. For example, some websites use applets, which are small programs written in Java that run inside your browser. To view these websites, you need to have a browser plugin that supports Java. Similarly, some software development tools, such as Eclipse, NetBeans, or IntelliJ IDEA, use Java as their base language or framework. To use these tools, you need to have a JDK (Java Development Kit) installed. The JDK is a software package that contains everything you need to develop and run Java applications. It includes a JRE, a compiler, a debugger, and other tools.
How to check if you have Java installed on your Windows Server 2019
Before you download and install the latest Java version for your Windows Server 2019, you may want to check if you already have it installed on your system. There are several ways to do this:
Use the command prompt to verify the Java version
One way to check if you have Java installed is to use the command prompt. To do this, - Open the command prompt by pressing Windows + R keys and typing cmd in the Run box. - Type java -version and press Enter. This will display the Java version, if any, installed on your system. For example, you may see something like this: java version "1.8.0_291" Java(TM) SE Runtime Environment (build 1.8.0_291-b10) Java HotSpot(TM) 64-Bit Server VM (build 25.291-b10, mixed mode) - If you see a message like "java is not recognized as an internal or external command", it means that you do not have Java installed or it is not added to your system path. Use the Control Panel to view the Java settings
Another way to check if you have Java installed is to use the Control Panel. To do this, - Open the Control Panel by clicking the Start button and typing Control Panel in the search box. - Click on Programs and then click on Java. This will open the Java Control Panel, which allows you to configure and manage your Java settings. - In the Java Control Panel, click on the About button in the General tab. This will display a window that shows the Java version, if any, installed on your system. For example, you may see something like this: Java(TM) Platform Standard Edition Version 8 Update 291 Build 1.8.0_291-b10 - If you do not see the Java Control Panel or the About button, it means that you do not have Java installed or it is not enabled on your system. Use the browser to test the Java plugin
A third way to check if you have Java installed is to use your browser. To do this, - Open your browser and go to This is a web page that tests if your browser has the Java plugin enabled and if it is up to date. - Click on the Agree and Continue button to allow the web page to run a Java applet. This will display a message that shows the Java version, if any, detected by your browser. For example, you may see something like this: Congratulations! You have the recommended Java installed (Version 8 Update 291). - If you see a message like "No working Java was detected on your system" or "Your Java version is out of date", it means that you do not have Java installed or it is not enabled or updated on your browser. How to download and install the latest Java version for Windows Server 2019
