The Java Development Kit (JDK), Java Virtual Machine (JVM) and the Java Runtime Environment (JRE) altogether is seen as a powerful trifecta of Java platform and its associated platform for developing and running Java applications. In this blog, we will discuss one of the most popular programming language's runtime environment (JRE).
JRE is an acronym for Java Runtime Environment. JRE is defined in technical terms as a group or set software system which is mainly designed to run other Java applications and software. Because the JRE contains the Java class loader, the Java class libraries, and also the Java Virtual Machine. JRE combine the JVM (Java Virtual Machine with the core classes and libraries. In this system, Java class loader is liable for properly loading classes and connecting them with the core Java class libraries. The JVM is accountable for making certain Java applications have the resources that they have to execute and perform flawlessly in your device or cloud environment. The JRE is predominantly considered as a container for those components and is responsible for providing an environment to run only Java program. If you want to know more about Java, it is highly recommended to learn Java.
Java software program has to be executed in order to get the desired output and to do that those java programs or software need an environment to run in. This is where runtime environment comes into play where it is allowed to load required class files and ensures there is sufficient memory to access and other system resources need to run a specific Java program. But this was not the case in the past, most software was relying on the operating system (OS) on the computer on which it runs. In this case, resources that are needed in this environment are memory and program files and dependencies. But Java Runtime environment (JRE) has changed all of that for Java programs.
