1-Introduction Java

Welcome to this first Java course in which we will learn how to program Java. Java is one of the most popular languages and it opens many possibilities as a developer, thanks to Java we can develop several types of web applications, mobile ... In this course we are going to approach the bases of the Java languageIn a first time I am going to present you the Java language then we will see the programming orienter object and to finish will carry out the installation of the environment of development which will enable us to carry out our first program in javaHistorically java is one of programming orienter object created by the societer Sun Microsystems in 1991 The first version was created in 1995 It was created to answer a need for portabilities between the operating systems Its slogan write once, Run everywhere that is to say write once, run everywhere A program written in java can be run on all operating systemsSun microsystem was bought by oracle in 2010 So what is java is an object oriented programming language also called OOPIt consists in grouping information and treatments in a block called objectAn object represents an idea, an idea, a concept and is defined by a class that will have attributes and methodsThe attributes correspond to all the characteristics of an objectAnd the methods correspond to all the actions that can perform the objectLet's take a car as an exampleThe cars in a common characterize but they can have different values, all the cars have wheels some cars have 4 or 6 or 8 as the truckEach car will have different characterize, An object is a container and autonomous that contains information and mechanisms concerning a subject,The object-oriented programming languages (such as PHP, python ) facilitate the organization of data and code in a more versatile way for larger projects. For the rest of this course we will focus on the installation of the tools that will allow us to run our first program in java
