JVM - an interpreter or compiler

Question

Could someone please give a concise answer for whether 'JVM is an interpreter or compiler'.. Possibly at an interview point of view.
Thanks

Answer 1

javac is a compiler to compile source code to bytecode i'e .Class file
java is a interpreter on behalf of part of JVM takes bytecode to be executed as machine level code
JVM has both JIT compiler and interpreter to speed up the execution process,
Internally it maintains HOTSPOT algorithm to execute code
if loops are there it takes process by compiler otherwise it takes interpreter,
It also maintains 'Code Verifier' to purify code whether it comes bytecode or not ,
so that it maintains a securety to mescellaneious files ,So JAVA is more secure Language
"finally Jvm uses both 'just in time compiler(JIT)' and interpreter.
