Java Is a programming Langauge Developed By James Gosling at SUN Microsystems and released in 1995 as a core Component in SUN Microsystems. History of java Open Office. Virtual Box. Vodafone System. Nokia Applications. Solaris Operating System. 4 What is JAVA ? JAVA Applications:
5 The Father of JAVA Name: James Gosling. Born: May 19 ,1955 (age 55). Residence: United Sates. Occupation: Computer Scientist. Employer: SUN microsystems Known For: Father of Java. In April 2nd, 2010, Gosling left Sun Microsystems which had recently been acquired by the Oracle Corporation. He wrote on his blog "Just about anything I could say that would be accurate and honest would do more harm than good"
7 Why JAVA ? Cross Platform 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
10 Why JAVA ? Object Oriented (OOP) 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 usedefficiently. Class. Object. Encapsulation. Inheritance. Polymorphism.
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)
17 JAVA Terminology JDK (Java Development Kit) Is a basic tool that is necessary to compile,documnetand 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 JAVA Terminology Ambiguity between a JDK and an SDK 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.
