Java Runtime Environment is software that functions to run all Java-based applications and is a technology produced and developed by Oracle.

The Java Runtime Environment (JRE) is a crucial component in the Java programming language ecosystem. JRE allows Java applications to run on various devices and operating systems without modifying the source code.

With this application, you can run Java-based programs called applets. The Java language was originally created by James Gosling while at Sun Microsystems (now part of Oracle) and was released in 1995. The language adopts much of the syntax from C and C++ but offers a simpler object-oriented model and minimal implementation dependencies.

Java applications are typically compiled into p-code (bytecode) and can run on any Java Virtual Machine (JVM). Java is a general-purpose programming language, specifically designed to minimize implementation dependencies. This functionality enables Java applications to run across multiple operating system platforms.

If you only want to run Java applications and do not intend to write Java code, then JRE is the software you need. Inside JRE, there is the java command that can be used to execute Java bytecode.

Over the years, the Java Runtime Environment has evolved rapidly and has been adopted across many platforms. With its motto “Write once, run anywhere”, Java has become one of the most popular programming languages today, widely used in the development of both desktop and web-based applications.

Many applications on Windows, macOS, or Linux require Java to function properly. For example, in the past, if you wanted to upload photos to Facebook, your computer first needed to have JRE installed.

Websites that use JavaScript, such as Facebook and Google, demonstrate Java-related functionality. For instance, when typing in Google’s search box, results appear dynamically. On Facebook, JavaScript enables interactive wall updates without refreshing the page.

Structure and Components of JRE:

Java Virtual Machine (JVM): The core component of JRE responsible for executing Java bytecode and translating it into machine code that can be run by the host operating system.
Java Class Library: A collection of Java classes that provides various functions and ready-to-use libraries for Java application development.
Configuration and Settings: JRE stores configuration and runtime settings for the Java environment, including network, security, and system configurations.

The Role of JRE in Java Applications:

Separation of Source Code and Execution: With JRE, Java source code is compiled into bytecode, separating the compilation process from execution. This allows applications to run on different systems without recompiling the source code.
Portability: One of Java’s main advantages is portability. Applications compiled into bytecode can run across multiple operating systems without modification.
Security: JRE introduces a strong security model that isolates Java applications from the host operating system, ensuring data integrity and security.
