Download Java for Windows Server 2016
If you are running a Windows Server 2016 machine, you might need to download and install Java on your system. Java is a popular programming language and a platform that enables you to run applications on different devices and platforms. In this article, we will explain what Java is, why you might need it, and how to download, install, verify, and update it on your Windows Server 2016 machine.
What is Java and why do you need it?
Java is a programming language and a platform
Java is a programming language that was created in 1995 by Sun Microsystems (now part of Oracle). It is designed to be simple, object-oriented, portable, and secure. Java code can be compiled into bytecode, which can be executed by a Java Virtual Machine (JVM). A JVM is a software that interprets and runs the bytecode on any device or platform that supports it.

Java enables you to run applications on different devices and platforms
One of the main advantages of Java is that it is platform-independent. This means that you can write a Java application once and run it on any device or platform that has a JVM installed. For example, you can run a Java application on Windows, Linux, Mac OS, Android, iOS, or even embedded devices. This makes Java suitable for developing cross-platform applications that can reach a wide range of users.
Java is required for some web applications and services
Another reason why you might need Java on your Windows Server 2016 machine is that some web applications and services require it. For example, some websites use Java applets or servlets to provide interactive features or dynamic content. Some web servers also use Java to handle requests and process data. If you want to access or host these web applications and services, you will need to have Java installed on your system.
How to download Java for Windows Server 2016?
Choose the right version of Java for your system
Before you download Java, you need to choose the right version for your system. There are two main types of Java: Java Runtime Environment (JRE) and Java Development Kit (JDK). JRE is the basic package that contains the JVM and the libraries needed to run Java applications. JDK is the complete package that contains the JRE as well as the tools needed to develop and debug Java applications. If you only want to run Java applications, you can download the JRE. If you want to develop or debug Java applications, you will need the JDK.
Another thing you need to consider is the bitness of your system. You can check whether your Windows Server 2016 machine is running a 32-bit or a 64-bit operating system by going to Settings > System > About. You will need to download the corresponding version of Java for your system. If you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit versions of Java.
