Here, we have noted some steps on how to install JRE(Jave Runtime Environment) on Windows, Mac and Linux. Java language is a high-level, class-based, object-oriented programming language designed to provide as little implementation dependence as possible. Java programing allows users to code freely and is supported on all platforms that support Java without recompilation. This programming language lets the developers write it once and run it anywhere.
The syntax for java programming is very similar to C language and C++; but it does fewer low-level facilities than either programming language. The JRE or Java Runtime Environment provides Java with dynamic capabilities like reflection and modification in runtime code; that are not available in any traditional compiled languages available across the globe.
Once, Java was considered one of the best and most popular programming languages globally. According to GitHub, Java is used mainly for client-server web applications, and it reported that; over 9 million developers were using Java language for their programs.
Creating Java language five primary goals or principles kept in mind in its creation. They are:
- It has to be simple, object-oriented, and familiar
- Be Robust and must be secure
- Have Architecture-neutral and be portable
- Executing with high performance
- Interpreted, threaded and dynamic
What Is The JRE?
The JRE(Java Runtime Environment) is a part of the Java platform itself. This platform is used to develop, run java programs and execute (also known as java virtual machine); which allows the same program file to run on many different platforms or operating systems available. But on the other hand, a java application requires a java runtime environment(JRE); and to install JRE, this does not depend on the operating system the developers are using.

JRE is a set of components used to create and run Java applications. The Java runtime environment comprises the java virtual machine, java class libraries, and the java classloader. It is also a part of a java development kit (JDK). All JDK, JRE, JVM are interrelated like JDKs are used in developing software. JREs provide the program with its programming tools and deployment technologies. Lastly, JVMs help in executing java programs.
Why Should You Have A JRE(Java Runtime Environment)?
A software to execute its program must have an environment to run on an operating system (OS) like; Linus, Unix, Microsoft Windows, or Mac operating system. Also, the Java runtime environment acts as a translator and facilitator between the Java program and the operating system.
Working of The JRE
The Java runtime environment abstracts the operating system, which creates a consistent platform to run and deploy Java applications. A Java runtime environment (JRE) runs on top of the Operating System and provides additional Java-specific resources. So, to run the program effectively, all three components of the JRE should work together within the environment; to successfully run a Java application on any operating system.
The Java class libraries themselves contain collections of prewritten code that we can call whenever needed. The class loader connects class libraries with Java virtual machine; and helps load the class loader into JVM while the program is running. After completion of all the processes, Java virtual machine executes the code.
- JDK = JRE + JVM (Software)
- JRE = JVM + ClassLoaders (Software)
- JVM = Java Interpreter + Threading + Garbage Collection (Virtual Machine)
What Does JRE Consist of?
The Java runtime environment has many other supporting software tools and features; to get the most out of any Java application.
- Deployment Solutions: These solutions are like Java Web Start and Java Plugin that makes the activation of applications; and provides support for further Java Updates available in the future.
- Development Toolkits: This contains toolkits designed to help developers improve their user interface.
- Integration Libraries: JRE provides many integration libraries to assist developers in creating data connecting between their applications and services.
- Language And Utility Libraries: Language and utility libraries include: the Java Runtime environment, Java-lang. and Java-util. Packages are also designed fundamentally with an association of Java applications, package versioning, management, and monitoring.
Steps To Install JRE In Your PC
How To Install JRE On Windows?
Download java for Windows from java.com
- The default options are generally okay to install.
- One should not install any additional advertised crap software
- Developers should never install the browser plugin or disable “web content” afterward in the Java settings.
How To Install JRE On Mac OS?
- If someone is upgrading from an earlier Java version, the user has to uninstall it beforehand.
- Install from the DMG file as usual.
- Download the installer from its website java.com.
- For more information regarding Java on macOS, see the links there to Oracle’s “install guide” or “system requirements.”
How To Install JRE On Linux?
The user should use a distribution package installer or manager to install a Java VM(JRE). This will also help Java to keep its version updated automatically.
- In the Linux Operating system, developers should install Oracle’s Java from its official website Java.com.
