Java is a widely-used programming language for building applications of different kinds. To gain a better understanding of Java, it’s crucial to be familiar with its key components and without a clear understanding of JDK vs. JRE vs. JVM, it can be challenging to navigate the Java ecosystem and create high-quality Java applications.

JDK (Java Development Kit)
The JDK is the complete software development kit for Java, including the JRE, development tools, and libraries for creating and running Java applications. It’s the primary tool for Java developers, required to write, compile, and run Java code. With the JDK, developers can create, test, and deploy Java applications with ease.
JRE (Java Runtime Environment)
The JRE is the environment in which Java applications run, including the JVM, class libraries, and other necessary components. It’s required to run Java code on a computer, but it does not include the development tools found in the JDK. The JRE ensures that Java applications run smoothly on any device with a JRE installed.
JVM (Java Virtual Machine)
The Java platform comprises of JDK, JRE, and JVM. The JDK is necessary for constructing Java programs, the JRE is essential to executing them, while the JVM is responsible for interpreting Java code. Understanding the differences and functionalities of these components is crucial for developers to create and deploy Java applications effectively.
