What is Sun Java Runtime Environment (JRE)?
JRE is a software package that provides the libraries, components and other resources needed to run Java applications and applets on various platforms.
JRE consists of two main components:
The Java Virtual Machine (JVM), which is a software layer that interprets and executes Java bytecode instructions.
The Java Class Library (JCL), which is a set of standard classes and interfaces that provide core functionality and support for various features of Java.
Why do you need JRE?
JRE enables cross-platform compatibility, security, performance and functionality of Java applications and applets.
Cross-platform compatibility means that you can run the same Java application or applet on different operating systems, such as Windows, Linux or Mac OS X, without any modification or recompilation.
Security means that JRE provides a sandbox environment that isolates Java applications and applets from the underlying system and prevents them from accessing unauthorized resources or performing malicious actions.
Performance means that JRE optimizes the execution of Java bytecode instructions by using techniques such as just-in-time compilation, garbage collection and adaptive optimization.
Functionality means that JRE supports various features of Java, such as networking, graphics, sound, database access, user interface, internationalization and more.
What are the system requirements for JRE?
The minimum hardware and software requirements for installing and running JRE version 1.4.2_05 on Windows are:
A Pentium processor with at least 166 MHz speed
At least 64 MB of RAM
At least 50 MB of free disk space
A compatible web browser that supports Java Plug-in (such as Internet Explorer or Netscape Navigator)
