Java is an object-oriented programming language used by numerous applications, websites, and even computer games. It’s specifically designed to require as few implementation dependencies as possible.
This also ensures cross-platform usability: if an app was developed using Java on Windows, then it can also be used on Mac or Linux with Java.
While Java developers need the Java Development Kit (JDK) to work, end users require another piece of software to run Java-based programs: the Java Runtime Environment (JRE).
For example, if you want to download the Java edition of Minecraft, you must first download JRE to be able to run Minecraft.
It’s incredibly easy to set up the JRE on your computer. Once you do this, you will be able to launch any tool created with JDK.
How to download Java JRE
To run Java files, you need to download JRE from the Oracle website. It’s not mandatory to also download the JDK if you’re not interested in Java application development.
JRE setup files are available for Windows, Solaris, macOS, and Linux. Depending on your computer’s architecture’s type, you can choose from Java 32-bit download and Java 64-bit download. Make sure to download the latest version available (updates are made automatically after setup).
Furthermore, you need to log in with an Oracle account to be able to download Java JRE, which you can create on the spot at no cost.
The setup files are pretty large, so it might take a while to finish downloading them, depending on the quality of your Internet connection.
As far as the installation process goes, you can enable Java content in your web browsers and change the default setup folder.
You don’t have to do anything else from this point on. Simply download, install and run your Java-based applications easily.
Using the Java Control Panel
If you need to configure JRE settings, you can do this from the Java Control Panel. For instance, you can toggle the Java web extension, add exceptions and allow websites to run Java apps, as well as remove temporary files from your computer and adjust the compression level for JAR files.
Meanwhile, advanced users are free to manage Java certificates, apply proxy configurations when connecting to the Internet, enable enhanced security restrictions, and configure debugging options.
Is Java JRE worth it?
It’s not a question of liking or disliking the Java Runtime Environment – you either need it or you don’t. It falls under the same category as Microsoft .NET Framework: software dependencies.
If you often visit websites, launch applications or play games that were built in the Java programming language, then you must have JRE installed on your computer to be able to use them.
Besides, JRE is completely free to use. It doesn’t take up a lot of space and doesn’t hamper your computer’s performance, so you can install and forget about it.
