Q: What do you understand by the term JVM?<\/strong><\/p>\n

Q: Differentiate between a JDK and a JVM.<\/strong><\/p>\n

A: JDK means Java Development Kit used for the purpose of development and also includes execution environment where JVM is purely run time environment and hence the source files cannot be compiled using a JVM.<\/p>\n
