Why JAVA ?
JAVA CHARACTERISTIC :
Cross Platform
Object Oriented Paradigm
Robust
Good Performance
Multi-Thread

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
Write Once Run Anywhere

Why JAVA ?
JAVA CHARACTERISTIC :
Cross Platform
Object Oriented Paradigm
10
OOP: is a programming paradigm that uses "objects " – “data structures”.
Data Structure: is a particular way of storing and organizing data in a computer so that it can be used efficiently.
Class.Object.Encapsulation.Inheritance.Polymorphism.
Why JAVA ?
OBJECT ORIENTED (OOP)
11
Why JAVA ?
JAVA CHARACTERISTIC :
Cross Platform
Object Oriented Paradigm
Robust
12
Why JAVA ?ROBUST
The Java programming language is designed for creating highly reliable software. It provides extensive compile-time checking, followed by a second level of run-time checking.
Memory Management
No Pointers
Automatic Garbage Collection (GC)

Why JAVA ?
GOOD PERFORMANCE
Just-in-time compilation in 1997 for Java 1.1
But Java programs are Slow.

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.
