Java Runtime Environment (JRE) allows you to play online games, chat with people worldwide, calculate your mortgage interest, and view 3D images.

It’s also integral to the intranet applications and other e-business solutions that are the foundation of corporate computing.

It provides the libraries, the Java Virtual Machine, and other components to run applets and applications in Java programming. In addition, two key deployment technologies are part of the JRE: Java Plug-in, which Enables Applets to Run in Popular Browsers, and Web Start, which deploys standalone applications over a network. Many cross-platform applications also require Java to operate properly.

It is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day.

The program is fastsecure, and reliable. Java is everywhere from laptops to data centers, game consoles to scientific supercomputers, and cell phones to the Internet! It is at the heart of the digital lifestyle. It’s the platform for launching careers, exploring human-to-digital interfaces, architecting the world’s best applications, and unlocking innovation everywhere—from garages to global organizations.

Main Features Java Runtime Environment

  • Java Virtual Machine (JVM): JRE includes a Java Virtual Machine (JVM) responsible for executing Java bytecode.
  • Class Libraries: It includes a set of class libraries that provide a wide range of functionality for Java programs. These libraries include collections, I/O, networking, security, and many other features.
  • Security: It provides a robust security model that ensures Java programs run in a secure environment. It includes sandboxing, code signing, and permission-based access control.
  • Automatic Memory Management: It includes automated memory management, which means that the JVM automatically manages the allocation and deallocation of memory for Java programs.
  • Platform Independence: Java programs that run on JRE are platform-independent, meaning they can run on any platform that has JRE installed, regardless of the underlying hardware or operating system.
  • Internationalization: It supports internationalization and localization, allowing Java programs to run in different languages and regions.
  • Deployment: It provides an easy and convenient way to deploy Java programs on various platforms, such as desktops, servers, and mobile devices.

How to Use

  • Install JRE: First, you need to download and install the latest version of JRE from the official Java website or FileHorse.
  • Write Java code: Next, write Java code using any text editor or integrated development environment (IDE) like EclipseNetBeans, or IntelliJ IDEA.
  • Compile Java code: Once you have written your Java code, you must compile it into byte code using the Java compiler. You can run the “javac” command in the command prompt or terminal.
  • Run Java program: After compiling your Java code, you can run it using the “java” command in the command prompt or terminal. This will execute the Java Virtual Machine (JVM) and load your byte code.
  • Test and debug: You can test and debug your Java program using various tools provided by the IDE or through the command prompt. This will help you find and fix any errors or bugs in your code.
  • Distribute Java program: Once you have tested and debugged your Java program, you can distribute it to others. You can package your code into a JAR (Java Archive) file and distribute it to others with JRE installed on their computers.

System Requirements

  • OS: Windows 7, 8, 8.1, 10, 11, Windows Server 2012, Windows Server 2016, and Windows Server 2019
  • Processor: It requires a minimum of a Pentium 2 266 MHz processor, although a faster processor is recommended for optimal performance.
  • Memory: It requires a minimum of 128 MB of RAM, although a larger amount of RAM is recommended for running complex Java programs.
  • Disk space: It requires a minimum of 124 MB of disk space for installation, although a larger amount of disk space is recommended for running Java programs.
  • Display: It requires a minimum display resolution of 800 x 600 pixels, although a higher resolution is recommended for better display quality.


  • Widely Supported Language
  • Platform Independence
  • Robust Standard Library
  • Automatic Memory Management
  • Strong Community Support


  • Slower Execution Speed
  • Steeper Learning Curve
  • Verbosity of Code


A Java Runtime Environment (JRE) is a software environment that provides a runtime platform for running Java programs. It includes a Java Virtual Machine (JVM), class libraries, and other features that make it easy for developers to create and run Java applications.

JRE is a powerful and flexible platform that offers features such as platform independence, automatic memory management, security, and internationalization. This makes it ideal for developing and running applications on various platforms, including desktops, servers, and mobile devices.

All in all, Java Runtime Environment (JRE) provides a reliable and robust platform for running Java applications, making it an essential tool for Java developers and users.
