The Java Development Kit (jdk):
- Software development environment used to develop, compile, debug, and package Java applications
- - Includes compiler (javac), debugger, and utilities like jar
- - Provides the JRE, so it also allows running Java programs.
- - Required by developers to write, compile, and debug code.
- - JDK is only for development (it is not needed for running Java programs)
- JDK is platform-dependent (different version for windows, Linux, macOS)
JVM (Java Virtual Machine)
- JVM is the core execution engine of Java. It is responsible for converting bytecode into machine-specific instructions.
- Part of both JDK and JRE.
- Performs memory management and garbage collection.
- Provides portability by executing the same bytecode on different platforms.
- Java Runtime Environment (JRE):
