Runtime environment for Java
Java Runtime Environment is a free development software created by Oracle. As its name suggests, it is a runtime environment that was specifically meant to run programs that were made in the Java programming language for computers. It provides the necessary libraries and resources for them to work properly.
Java Runtime Environment is just one of the essential tools that programmers need to work with Java, including Eclipse and the Java Development Kit. They ensure that developers have all resources that they need to start creating programs and applications for computers.
What is it?
The Java Runtime Environment, sometimes referred to as JRE, is essentially a software layer that runs on top of your operating system. It provides the necessary libraries and resources that programs made using Java need to run and work properly on your computer. Together with the Java Virtual Machine and the Java Development Kit, they form a trifecta of platform components needed for developing using this particular programming language.
There are basically three parts that work in the Java Runtime Environment. The Class Loader is responsible for correctly loading classes and connecting them with core Class Libraries. Meanwhile, the JVM ensures Java applications have the resources they need to run properly. Then, the JRE itself mainly serves as a container for these components and is responsible for facilitating their activities.
Just a few things to note, though. The first is that JRE is just one part of a system of components that are needed to program in Java. You will also need JDK for compiling programs afterward. The other is that using this tool, and programming in general, is not meant for beginners as it requires extensive knowledge of coding before you can even begin to use these tools properly.
An essential component for Java programming
All in all, whether you're new to Java programming or you're a returning veteran looking to code in this language again, the Java Runtime Environment is an essential component that you need to have installed before you start. Just know that you will also need the Java Development Kit to complete the package. Recommended.
