Introduction




Java is a general-purpose, object-oriented, and platform-independent programming language that was created by James Gosling at Sun Microsystems in 1995. It is designed to be simple, secure, portable, robust, and high-performance.


Java runs on a virtual machine called the Java Virtual Machine (JVM), which translates the compiled Java code into machine code that can be executed by any operating system. This makes Java applications compatible with different platforms, such as Windows, Linux, Mac OS, Android, etc.


Java also comes with a rich set of libraries and tools that provide various functionalities, such as networking, database access, user interface design, graphics, security, etc.


Java 12 is the latest version of Java, which was released in March 2019. It is a non-long-term support (LTS) version, which means that it will receive updates only until September 2019. The next LTS version will be Java 17, which is expected to be released in September 2021.


Java 12 introduces some new features and enhancements to the language and the platform, such as:


  • Switch expressions: A new syntax for writing switch statements that can return values and use lambda-like syntax.



  • Teeing collectors: A new collector for streams that allows splitting a stream into two collectors and combining their results.



  • Compact number formatting: A new API for formatting numbers in a compact way, such as "1K" instead of "1000".



  • New methods in String class: Some new methods for manipulating strings, such as indent(), transform(), describeConstable(), and resolveConstantDesc().



  • JVM constants API: A new API for modeling nominal descriptions of key class-file and run-time artifacts.



  • Miscellaneous improvements: Some other improvements in performance, compatibility, security, garbage collection, etc.



If you want to try out these new features and enhancements, you will need to download and install Java 12 on your Windows system. Before you do that, you will need to check some prerequisites and system requirements.

Check if Java Is Already Installed




Before you download and install Java 12, you should check if you already have Java installed on your system. This will help you avoid unnecessary downloads and installations, and also let you know if you need to update your existing Java version.


To check if Java is already installed on your Windows system, you can use the command prompt. Here are the steps to follow:


  • Open the command prompt by pressing the Windows key + R and typing cmd in the Run dialog box.



  • Type java -version and press Enter. This will display the current Java version installed on your system, if any.



  • If you see a message like "java version '12.0.1'", then you already have Java 12 installed and you don't need to download or install anything else.



  • If you see a message like "java version '11.0.4'", then you have an older version of Java installed and you might want to update it to Java 12.



  • If you see a message like "'java' is not recognized as an internal or external command, operable program or batch file.", then you don't have Java installed on your system and you will need to download and install it.



In this article, we will assume that you don't have Java installed on your system or you want to update it to Java 12. If that is the case, then you can proceed to the next section.


Download Java 12 for Windows




To download Java 12 for Windows, you will need to visit the Oracle Java Downloads page and choose the right installation file for your system. Here are the steps to follow:


  • Open your web browser and go to . This is the official page for downloading archived versions of Java Development Kit (JDK), which includes the JVM and other tools for developing Java applications.



  • Scroll down to the section that says "Java SE Development Kit 12.0.2". This is the latest update of Java 12 as of June 2021.



  • Under this section, find the file that matches your system architecture and operating system. For example, if you have a 64-bit Windows system, then you should choose the file that says "Windows x64 Installer".



  • Click on the file name to start downloading it. You might need to sign in with your Oracle account or create one if you don't have one already.



  • Read and accept the license agreement by clicking on the checkbox that says "I reviewed and accept the Oracle Technology Network License Agreement for Oracle Java SE".



  • Click on the Download button to continue downloading the file. Save it in a location where you can easily find it later.



Once the download is complete, you can proceed to install Java 12 on your Windows system.

To install Java 12 on Windows, you will need to run the downloaded file and follow the installation wizard steps. Here are the steps to follow:


  • Locate the downloaded file in your file explorer and double-click on it to run it. You might see a security warning asking if you want to run this file. Click on Run or Yes to continue.



  • The installation wizard will start and welcome you to the setup process. Click on Next to proceed.



  • The wizard will ask you to choose a destination folder for installing Java 12. You can either accept the default location or browse for a different one. Click on Next to continue.

  • Once the installation is complete, the wizard will show a message saying "Installation Completed". Click on Close to exit the wizard.



Congratulations! You have successfully installed Java 12 on your Windows system. Now, you need to set some environmental variables in Java to make it work properly.


Set Environmental Variables in Java




Environmental variables are settings that tell your system where to find certain files or programs. In order to use Java from any location on your system, you need to set some environmental variables in Java that point to the installation folder of Java 12 and the Java executable file.


To set environmental variables in Java, you need to follow these steps:


  • Open the Control Panel by clicking on the Start menu and typing Control Panel in the search box.



  • Click on System and Security, then click on System.



  • Click on Advanced system settings on the left side of the window. This will open the System Properties dialog box.



Click on the Advanced tab, then click on the Environment Variables button at the bottom of the dialog box. This
