What is the difference between JDK and JVM?
The Java development kit (JDK) contains tools for Java development, and the Java Runtime Environment (JRE) contains a JVM to convert byte code .class to machine code, and execute it, in short, the JRE runs Java program. We can use javac -version to find out the version of the installed JDK.
The Java development kit (JDK) is NOT the same thing as the Java runtime environment (JRE). The java command gives the version of the JRE, the runtime environment. “javac -version” would give you the version of the Java development kit.
