What is “Java”

• “Java” can be refer to– Programming language– Virtual Machine– Technology Platform

4

Java As a Programming Language

• “Simple”, “Objected Oriented”, “Familiar”– based upon C / C++ syntax

• "robust and secure"– Sandbox security model, bytecode verification– automatic memory management, no pointer operation

• (Machine) “Architecture Neutral and Portable”

• “Interpreted, Threaded, and Dynamic”

“Java” as Virtual Machine

Java Application Code

Operating System

Java API’s

Memory Manager (Garbage Collection)

Interpreter/JIT Compiler

Bytecode Verifier

JRE

Source code is compiled to Java bytecode, which is verified, interpreted or JIT-compiled for the native architecture.

The Java APIs and JVM together make up the Java Runtime Environment (JRE).

Java and Openess

31

Java: the Most Open Technology PlatformOpen != “Open Source != Free

• Java the Language Specifications / features are “open” to the community

• Java the Platform Specifications are open to the community

• Java the Virtual Machine Implementation is completely independent from the Specification

32

Criteria for “Open Specification”

• not controlled by one company / entity– including life cycle

• public

• readily available

• unprotected
