About Course

Ce cours introduit la programmation orientée objet (encapsulation, abstration, héritage, polymorphisme) en l'illustrant en langage Java. Il présuppose connues les bases de la programmation (variables, types, boucles, fonctions, ...). Il est conçu comme la suite du cours « Initiation à la programmation (en Java) ». Comme son prédécesseur, ce cours s'appuie sur de nombreux éléments pédagogiques : vidéos sous-titrées, quizz dans et hors vidéos, exercices, devoirs notés automatiquement, notes de cours.

Course Syllabus

Cette semaine aborde l'initialisation des objets (via ce qu'on appelle des « constructeurs »), ainsi que ce qui se passe lorsque l'on affiche, compare et affecte des objets en Java. La question de comment se passe la « fin de vie » des objets est aussi abordée.

Java (software platform) The "Java Development Kit" ("JDK") is a Sun product aimed at Java developers. Since the introduction of Java, it has been by far the most widely used Java software development kit (SDK). It contains a Java compiler, a full copy of the Java Runtime Environment (JRE), and many other important development tools.
Java Java is divided into four provinces, West Java, Central Java, East Java, and Banten, and two special regions, Jakarta and Yogyakarta.
Java (software platform) The Java platform has become a mainstay of enterprise IT development since the introduction of the Enterprise Edition in 1998, in two different ways:
Java West Java is wetter than East Java and mountainous regions receive much higher rainfall. The Parahyangan highlands of West Java receive over 4,000 mm annually, while the north coast of East Java receives 900 mm annually.
Java performance Since late 1990s, the execution speed of Java programs improved significantly via introduction of just-in-time compilation (JIT) (in 1997 for Java 1.1), the addition of language features supporting better code analysis, and optimizations in the JVM (such as HotSpot becoming the default for Sun's JVM in 2000). Hardware execution of Java bytecode, such as that offered by ARM's Jazelle, can also offer significant performance improvements.
Java In 1815, there may have been five million people in Java. In the second half of the 18th century, population spurts began in districts along the north-central coast of Java, and in the 19th century population grew rapidly across the island. Factors for the great population growth include the impact of Dutch colonial rule including the imposed end to civil war in Java, the increase in the area under rice cultivation, and the introduction of food plants such as casava and maize that could sustain populations that could not afford rice. Others attribute the growth to the taxation burdens and increased expansion of employment under the Cultivation System to which couples responded by having more children in the hope of increasing their families' ability to pay tax and buy goods. Cholera claimed 100,000 lives in Java in 1820.
Objet Geometries Objet is one of the brands of Stratasys, a maker of 3D printers. The brand began with Objet Geometries Ltd, a corporation engaged in the design, development, and manufacture of photopolymer 3D printing systems. The company, incorporated in 1998, was based in Rehovot, Israel. In 2011 it merged with Stratasys. It held patents on a number of associated printing materials that are used in "PolyJet" and "PolyJet Matrix" polymer jetting technologies. It distributed 3D printers worldwide through wholly owned subsidiaries in the United States (Objet Geometries Inc), Europe (Objet Geometries GmbH), and Hong Kong. Objet Geometries owned more than 50 patents and patent-pending inventions.

Java During the Napoleonic wars in Europe, the Netherlands fell to France, as did its colony in the East Indies. During the short-lived Daendels administration, as French proxy rule on Java, the construction of the Java Great Post Road was commenced in 1808. The road, spanning from Anyer in Western Java to Panarukan in East Java, served as a military supply route and was used in defending Java from British invasion.
Java (cigarette) Java comes in four varieties: regular Java, Java Novaya (Java New), Java Zolotaya (Java Gold) and Java Export.
Java (programming language) Programs written in Java have a reputation for being slower and requiring more memory than those written in C++. However, Java programs' execution speed improved significantly with the introduction of just-in-time compilation in 1997/1998 for Java 1.1, the addition of language features supporting better code analysis (such as inner classes, the StringBuilder class, optional assertions, etc.), and optimizations in the Java virtual machine, such as HotSpot becoming the default for Sun's JVM in 2000. With Java 1.5, the performance was improved with the addition of the java.util.concurrent package, including Lock free implementations of the ConcurrentMaps and other multi-core collections, and it was improved further Java 1.6.
Java Java (Indonesian: Jawa; Javanese: ꦗꦮ; Sundanese: ᮏᮝ) is an island of Indonesia. With a population of over 141 million (the island itself) or 145 million (the administrative region) Census released in December 2015, Java is home to 56.7 percent of the Indonesian population and is the most populous island on Earth. The Indonesian capital city, Jakarta, is located on western Java. Much of Indonesian history took place on Java. It was the center of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally.
Java A wider effect of this division is the number of sects. In the middle of 1956, the Department of Religious Affairs in Yogyakarta reported 63 religious sects in Java other than the official Indonesian religions. Of these, 35 were in Central Java, 22 in West Java and six in East Java. These include Kejawen, Sumarah, Subud, etc. Their total membership is difficult to estimate as many of their adherents identify themselves with one of the official religions.
Objet petit a In the Seminars "L'angoisse" (1962–1963) and The Four Fundamental Concepts of Psychoanalysis (1964), "objet petit a" is defined as the leftover, the remnant left behind by the introduction of the Symbolic in the Real. This is further elaborated in the Seminar "The Other Side of Psychoanalysis" (1969–1970), where Lacan elaborates his Four discourses. In the discourse of the Master, one signifier attempts to represent the subject for all other signifiers, but a surplus is always produced: this surplus is "objet petit a", a surplus meaning, a surplus of jouissance.
Introduction (writing) Keeping the concept of the introduction the same, different documents have different styles to introduce the written text. For example, the introduction of a Functional Specification consists of information that the whole document is yet to explain. If a Userguide is written, the introduction is about the product. In a report, the introduction gives a summary about the report contents.
Java Java is almost entirely of volcanic origin; it contains thirty-eight mountains forming an east–west spine that have at one time or another been active volcanoes. The highest volcano in Java is Mount Semeru (3,676 m). The most active volcano in Java and also in Indonesia is Mount Merapi (2,930 m).
Java Java lies between Sumatra to the west and Bali to the east. Borneo lies to the north and Christmas Island is to the south. It is the world's 13th largest island. Java is surrounded by the Java Sea to the north, Sunda Strait to the west, the Indian Ocean to the south and Bali Strait and Madura Strait in the east.
Objet Geometries On April 16, 2012 Objet announced that it agreed to merge with Stratasys, a leading manufacturer of 3D printers; in an all-stock transaction. Stratasys shareholders were expected to own 55 percent and Objet shareholders were expected to own 45 percent of the combined company. The merger was completed on December 3, 2012 the market capitalization of the new company was approximately $3.0 billion.
Java Java has been traditionally dominated by an elite class, while the people in the lower classes were often involved in agriculture and fishing. The elite class in Java has evolved over the course of history, as cultural wave after cultural wave immigrated to the island. There is evidence that South Asian emigres were among this elite, as well as Arabian and Persian immigrants during the Islamic eras. More recently, Chinese immigrants have also become part of the economic elite of Java. Although politically the Chinese generally remain sidelined, there are notable exceptions, such as the governor of Jakarta, Basuki Tjahaja Purnama. Though Java is increasingly becoming more modern and urban, only 75% of the island has electricity. Villages and their rice paddies are still a common sight. Unlike the rest of Java, the population growth in Central Java remains low. Central Java however has a younger population than the national average. The slow population growth can in part be attributed to the choice by many people to leave the more rural Central Java for better opportunities and higher incomes in the bigger cities. Java's population continues to rapidly increase despite many Javanese leaving the island. This is somewhat due to the fact that Java is the Business, Academic, and Cultural hub of Indonesia, which attracts millions of non-Javanese people to its cities. The population growth is most intense in the regions surrounding Jakarta and Bandung, which is reflected through the demographic diversity in those areas.
