Can you explain the differences between Java Runtime Environment, Java Virtual Machine, and Java Development Kit?

• Java Virtual Machine (JVM) — is a virtual machine that executes Java bytecode. It provides platform independence by interpreting the bytecode and managing memory during program execution.

• Java Runtime Environment (JRE) — is the environment for running Java applications, including the JVM and standard class libraries necessary to run Java programs. JRE does not contain development tools.

• Java Development Kit (JDK) — is a complete set for Java development, including JRE, compiler (javac), debugger, and other tools for writing, compiling, and debugging Java applications.

Example: to run a pre-compiled Java application, a JRE is sufficient, but for writing and compiling code, a JDK is needed.
