The programmers need not put any extra effort into making modifications for it to run properly. The JRE ensures that it supports program code irrespective of the system. Though every JRE comes along with a default JVM, the developers can still feel free to choose the one that caters to their needs. The Java Virtual Machine or JVM executes the live Java applications. It is important to make note that the JDK and JRE are compatible with each other. Some examples are Java Enterprise Edition (Java EE), Java Special Edition (Java SE), and Java Mobile Edition (Java ME). The JDKs are usually picked according to the Java version or edition. Java Development Kit or the JDK is a set of tools to develop Java applications. The other two components are Java Development Kit (JDK) and Java Virtual Machine (JVM). The JRE is just one of the three interrelated components that let us develop and run Java applications. In other words, we can denote it as a meta-OS for java code. It is organized in a way that each layer provides the services that the layers present above it use. The Java Runtime Environment or JRE is a series of layers that are present on top of a computer’s operating system software and provides class libraries and other resources when needed. The role of this environment is to provide access to the memory and the other resources required for the process. to execute a software program, we need an environment to run it. The Java Runtime Environment is software that helps us run other software in it. This article will lend a helping hand in knowing such details about the Java Runtime Environment. As a developer, it is indeed important for you to know about the JRE and its operations. The Java Runtime Environment plays a vital role in the Java platform.
