CROSS PLATFORM

Why JAVA ?

First : what is a Platform ?

Platform: describes some sort of hardware architecture and software framework (including application frameworks), that allows software to run.

Framework: are a special case of software libraries in that they are reusable abstractions of code wrapped in a well-defined API.

JAVA is WORA

JAVA Terminology

JDK (Java Development Kit)

Is a basic tool that is necessary to compile,documnet and package java programs (javac – java - ) it include JRE.

JRE (Java Runtime Environment) is a Runtime environment that implements Java Virtual Machine it provides all class libraries. It should installed on a pc that run java Programs.

JVM (Java Virtual Machine)

VM: is a software implementation of a machine that executes programs like a physical machine.

SDK (Software Development Kit)

18

Ambiguity between a JDK and an SDK

JAVA Terminology

JDK is :(Java Development Kit)

SDK is :(Software Development Kit)

The JDK forms the subset of the SDK which is responsible for the writing and running of Java programs. The remainder of the SDK is composed of extra software, such as Application Servers, Debuggers, and Documentation.
