The JDK (Java Development Kit), JRE (Java Runtime Environment), and JVM (Java Virtual Machine) are key components of Java’s ecosystem, each serving a distinct purpose. The JDK is a full software development kit that includes tools for writing, compiling, and debugging Java applications, along with the JRE. The JRE, on the other hand, provides the necessary libraries and the JVM to run Java applications but doesn’t offer development tools like the JDK. The JVM is a virtual machine that executes Java bytecode, providing a platform-independent environment. In summary, the JDK is for developers, the JRE is for users, and the JVM is the engine that runs Java programs.
