The Java Classloader is a part of the Java Runtime Environment that dynamically loads Java classes into the Java Virtual Machine. Usually classes are only loaded on demand. The Java run time system does not need to know about files and file systems because of class loaders. Delegation is an important concept to understand when learning about class loaders. A software library is a collection of more or less related object code. In the Java language, libraries are typically packaged in Jar files.

  • The Java Classloader is a part of the Java Runtime Environment that dynamically loads Java classes into the Java Virtual Machine. Usually classes are only loaded on demand. The Java run time system does not need to know about files and file systems because of class loaders. Delegation is an important concept to understand when learning about class loaders. A software library is a collection of more or less related object code. In the Java language, libraries are typically packaged in Jar files. Libraries can contain various, different sorts of objects, the most important type of object contained in a Jar file is a Java class. A class can be thought of as a named unit of code. The class loader is responsible for locating libraries, reading their contents, and loading the classes contained within the libraries. This loading is typically done "on demand", in that it does not occur until the class is actually used by the program. A class with a given name can only be loaded once by a given classloader.
  • Le chargeur de classe java (Java Classloader) est une partie du JRE (Java Runtime Environment) qui charge dynamiquement les classes java dans la machine virtuelle java. En général, les classes sont chargées seulement à la demande. Le JRE n'a pas besoin de savoir quels sont les fichiers et systèmes de fichiers correspondants grâce au chargeur de classe. Le chargeur de classe se charge de retrouver l'emplacement des bibliothèques logicielles, de lire leur contenu et de charger les classes qu'elles contiennent.
