On-board A/D converter MCP3204 with a potentiometer is used for testing multiple A/D conversions. Fast, on-board USB 2.0 programmer. How to check if a file exists in Java. [Serialisation] methode générique ? iSpectrum compile java pour l'iPhone et l'iPad. Développée par la société FlexyCore , une société fondée à Rennes en 2008 par des experts Java issus de Texas Instrument et de l’INRIA, la solution iSpectrum permet de coder et débugger, en JAVA, des applications natives pour iPhone et iPad. Pour cela, iSpectrum compile les classes Java en Objective-C et utilise le SDK d’Apple pour produire le binaire des applications. L’accès aux APIs propres à l’iPhone est possible, notamment pour tous les éléments d’interface ou la gestion de l’accéléromètre et du GPS. D’autres devraient rapidement suivre, par exemple celles qui permettent de faire de la 3D avec le support d’OpenGL ES.
À noter que la solution permet de piloter directement le SDK conçu pour l’iPhone afin de faciliter la simulation pour les phases de test. Ainsi il est possible pour les possesseurs de Mac : De porter un projet J2ME vers l’Iphone. De développer sous JAVA (1.5 idem Android) des applications natives iPhone/iPad avec les performances du natif.
The Java™ Tutorials. The Java Tutorials have been written for JDK 8. Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available. See Java Language Changes for a summary of updated language features in Java SE 9 and subsequent releases. See JDK Release Notes for information about new features, enhancements, and removed or deprecated options for all JDK releases. The Java Tutorials are practical guides for programmers who want to use the Java programming language to create applications. They include hundreds of complete, working examples, and dozens of lessons.
Groups of related lessons are organized into "trails". Trails Covering the Basics These trails are available in book form as The Java Tutorial, Sixth Edition.

Java is a simple and yet powerful object oriented programming language and it is in many respects similar to C++. Java originated at Sun Microsystems, Inc. in 1991. It was conceived by James Gosling, Patrick Naughton, Chris Warth, Ed Frank, and Mike Sheridan at Sun Microsystems, Inc. It was developed to provide a platform-independent programming language. This site gives you an Introduction to Java Programming accompanied with many java examples.
Platform independent Unlike many other programming languages including C and C++ when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. Java Virtual Machine What is the Java Virtual Machine? Java was designed with a concept of ‘write once and run everywhere’. Object Oriented Programming Since Java is an object oriented programming language it has following features: OOP Concepts Four principles of Object Oriented Programming are Abstraction Encapsulation Inheritance Polymorphism.
