Workflow:
Source Code -->> Byte Code -->> Binary Code

Human code -> hello.java
-> Compiler -> hello.class
-> JVM -> hello.bin

Java Development Kit (JDK)
Compiler + JRE

Java Runtime Environment(JRE)
Java Virtual Machine(JVM) + Libraries

JRE: Platform Independence, Memory Management, Class Libraries, Security, Multithreading

Compile Time:
Source code to Byte Code time
Run Time:
Byte code to Binary code time

Features of Java:
Simple, Easy to learn, portal, Platform independent, OOPs.
