As you can see there is no any import for Gson class instead we load and use it in runtime. Example: A specific query This query result shows us that there are two types of ClassLoaders and each has many instances: AggregatedClassLoader and JarClassLoader. The AggregatedClassLoader contains a flat list of other ClassLoaders (not a hierarchy) to load classes from that ‘child’ ClassLoader where they are first found. The JarClassLoader Class The JarClassLoader class extends java.net.URLClassLoader.

Trail: Deployment Lesson: Packaging Programs in JAR Files The JarClassLoader Class The JarClassLoader class extends java.net.URLClassLoader.As its name implies, URLClassLoader is designed to be used for loading classes and resources that are accessed by searching a set of URLs. The URLs can refer either to directories or to JAR files. In addition to subclassing URLClassLoader, JarClassLoader …

java.net.URLClassLoader Example, In this example we shall show you how to make use of URLClassLoader, This class can be used to load a Class or a collection of classes that The following examples show how to use java.net.URLClassLoader. These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go I'd be interested in an example of that because I don't see how to do it.
