JRE or ” Java Runtime Environment ” is a set of software tools that are used to develop Java applications.
It combines Java Virtual Machine ( JVM ), platform core classes and supporting libraries. JRE is a part of Java Developement Kit (JDK), but it can also be downloaded separately.
The full form of JRE is ” Java Runtime Environment ” and it is also written as ” Java RTE “. As you probably know that Java is a programming language, which is quite similar to C.
Since it is a new language, so many operating systems do not support it natively. In such a situation, you need a Java Runtime Environment to be installed in your computer so that Java applets and Java applications can be run.
These JREs, or Java RTEs, have been developed by Sun Microsystems (which are creators of Java) and include Java Virtual Machine (JVM), code libraries, and components, which are required to run Java programs. for.
This JRE is available for multiple computer platforms, including Mac, Windows , and Unix.
In such a situation, if JRE is not installed in any computer, then Java programs should not be recognized by the Operating System so that those programs will not run.
This JRE software provides a runtime environment in which Java programs can be executed, such as software programs that are fully compiled for the computer ‘s processor .
JRE software is available on both a standalone environment and a Web browser plug-in which allows Java applets to be run in a web browser itself.
