❓ Frequently Asked Questions
What is the Java Development Kit (JDK)?
The JDK is a complete toolkit for Java development. It provides the compiler, runtime, debugger, and libraries needed to write, compile, and run Java programs.
What tools are included in the JDK?
Core tools include javac (compiler), java (runtime launcher), jdb (debugger), jar (packaging), and javadoc (documentation generator).
How is the JDK different from JRE and JVM?
JDK is for development and includes tools; JRE is for running Java apps; JVM is the virtual machine that executes bytecode. The JDK includes the JRE.
Do you need the JDK to run Java programs?
For running existing Java programs you need a runtime environment (JRE). The JDK includes a JRE and is required to write and compile Java code.
