JDK :-it means that we r developing applications,after
developing we r compiling a program through javac.Here the
javac is in jdk part.after compiling it makes a .class
file(nothing but a bytecode),bytecode contains assembly
language,here byte is 8 bits so it's cpacity is 255,here 255
is contains opcodes(operation codes) values.That is jvm is
not a part of jdk.

JRE :-it means excecution(running) a program.here we r
having jvm in jre.first of all bytecode is loaded on jvm
that is nothing but a assembly language will be converted
into java virtual machine language

JVM :-it is the form ofjava virtual machine language of
bytecode,now the jvm language will provide the message of
output in user understandable language(high level lang).
