Typical Java Development Environment

There are 5 phases in java development environment.

1. Editor : Program is created in an editor and stored on disk in a file ending with .java
2. Compiler:  creates bytecodes and stores them on a disk in a file ending with .class
3. Class Loader: Class loader reads .class files containing bytecodes from disks and put those bytecodes in memory.
4. Bytecode Verifier: Bytecode verifier confirms that all bytecodes are valid and do not violate java's security restrictions.
5. JVM: To execute the program, JVM reads bytecodes and translates them into a language that the computer can understand.

EDIT=>>COMPILE=>> LOAD=>>VERIFY=>>EXECUTE

BYTECODE: Bytecode is the form of instructions that the JVM executes. They are the machine language of the JVM.
