A Java Runtime Environment (JRE) is the base set of data files and programs (executables) which are required to run Java Applications. Typically, this consists of a Java Virtual Machine (a virtual computer/processor which the Java program runs 'on'), the Java Libraries (definitions of objects and functionality which Java programs can utilise), and any additional supporting software.
If you have been instructed to get java so that you may use a certain website or piece of software, this means you are required to install a JRE.
The 'standard' JRE is developed by Sun Microsystems, the original developers of Java, and is available at http://java.sun.com/
Typically, each JRE version has had multiple updates since its initial release, so you will probably need to download a file called something like Java 6 update 2, or JRE 6 update 2, or even referred to via shorthand like Java 6u2.
To test which version of a JRE is installed (if any), run the command "java -version" in a command-line (Windows) or Terminal (Unix/Linux/Mac).
Other run-time implementations of Java are available under different license conditions, although most focus on the actual JVM itself, rather than completely re-implementing all of the additional tools and libraries.
The JRE is distinct from the JDK (Java Development Kit) in that the JDK contains additional software which is required only for developing Java applications - such as the Java Compiler javac, and which most users will not require.
The Java Runtime Environment (JRE) provides the libraries, the Java Virtual Machine, and other components to run applets and applications written in the Java programming language. In addition, two key deployment technologies are part of the JRE: Java Plug-in, which enables applets to run in popular browsers; and Java Web Start, which deploys standalone applications over a network.

Who invoke main function in java?
The Java Runtime Environment invokes main methods.
Will Java runtime environment affect your PC?
Probably not, unless you run a virus written in Java.
What is ther role of jre in java?
JRE stands for Java Runtime Environment. JRE is the runtime set up that is required by the JVM to execute java programs. The JRE and JVM (Java Virtual Machine) come packaged along with the Java Development Kit (JDK) that we download and install from the suns website to install Java.
What translates a Java program into Bytecode?
The Java Runtime Environment (JRE) converts the byte code to machine language.
What is J2Se runtime?
The J2SE Runtime Environment is a platform that enables quick development and execution of Java applications. It was developed by Sun Microsystems.
What is java's purpose on my PC?
Programs that are specifically designed with Java require a Java runtime to work on a computer. (In the case of Java, the runtime is called "Java Virtual Machine".) If you have any such program, you need to have Java.
Where can one download a java runtime environment?
The java runtime environment can be downloaded from several websites. Among them are Oracle, Java, CNET, Softsonic, Eclipse, AfterDawn, Soft32, and OldApps.
Can i read value in JAVA at runtime?
Yes you can...
Can you use programs in Java under Windows 8.1?
Yes you can but for that you must have have a Java Runtime Environment installed in your computer. Also if you are talking about programming in java then you need to install a Java SDK which can help you in executing your java code and run it. (It also contains Java Runtime Environment).
Why cant you run java on Windows 8?
You may have to install Java runtime support.

What will java software do for you on your laptop?
The general Java Runtime Environment allows a computer to run Java applets and compiled Java files.

Probably not, unless you run a virus written in Java.

Why and amp How is Java is Better For What if your Enterprise Application?
Java is defined by a specification and consists of a programming language, a compiler, core libraries and a runtime (Java virtual machine) The Java runtime allows software developers to write program code in other languages than the Java programming language which still runs on the Java virtual machine. The Java platform is usually associated with the Java virtual machine and the Java core libraries.
