How to Download and Install JRE (Java Runtime Environment) on Your Computer
If you want to run Java applications or applets on your computer, you need to have JRE (Java Runtime Environment) installed. JRE is a software package that provides the necessary libraries, tools, and components to execute Java programs. In this article, we will explain what JRE is and why you need it, how to check if you have it installed on your computer, how to download it from the official website, how to install it on your computer, and how to verify if it is working properly.

What is JRE and Why Do You Need It?
JRE is one of the three interrelated components for developing and running Java programs. The other two components are JDK (Java Development Kit) and JVM (Java Virtual Machine). Let's see how they differ and relate to each other.
JRE vs JDK vs JVM
JDK is a set of tools for developing Java applications. It includes a compiler, a debugger, a documentation generator, and other utilities. It also contains a compatible JRE, which is required to run Java programs.
JVM is a software layer that runs on top of your operating system and interprets Java bytecode. Java bytecode is the result of compiling Java source code using the JDK. JVM enables Java programs to run on any platform that supports JVM, without requiring any modification.
JRE is a subset of JDK that contains only the essential components to run Java programs. It includes JVM, Java class libraries, and other resources. It does not include any development tools or compilers.
So, if you are only interested in running Java programs on your computer, you only need JRE. If you are planning to develop Java programs, you need JDK instead.
JRE Components and Functions
JRE consists of the following main components:
Class Loader: It dynamically loads all the classes needed to run a Java program.
Bytecode Verifier: It checks the format and accuracy of Java bytecode before passing it to the interpreter.
Interpreter: It creates an instance of JVM that executes the Java bytecode natively on your machine.
Deployment Solutions: They simplify the activation of Java applications and provide support for future updates. They include Java Web Start and Java Plugin.
Development Toolkits: They help developers improve their user interface. They include Swing, AWT, JavaFX, Image I/O, Sound, etc.
Base Libraries: They provide core functionality for Java programs. They include lang and util, networking, security, math, XML processing, etc.
