Loading a class dynamically is easy. All you need to do is to obtain aClassLoaderand call itsloadClass()method. Here is an example: public class MainClass { public static void main(String[] args){ ClassLoader classLoader = MainClass.class.getClassLoader(); try { Class aClass = classLo...
Applications implement subclasses of ClassLoader in order to extend the manner in which the Java virtual machine dynamically loads classes. Class loaders may typically be used by security managers to indicate security domains. In addition to loading classes, a class loader is also responsible for loc...
The network class loader subclass must define the methodsfindClassandloadClassDatato load a class from the network. Once it has downloaded the bytes that make up the class, it should use the methoddefineClassto create a class instance. A sample implementation is: class NetworkClassLoader extends ...

ClassLoader是Java的类加载器,用于把class文件加载到JVM中,下面大概了解一下Java类加载器的概况。 一,java提供的加载器 Java提供了三个ClassLoader: 1,BootstrapClassLoader 用于加载JAVA核心类库,也就是环境变量的%JRE_HOME%\lib下的rt.jar、resources.jar、charsets.jar等。
Applications implement subclasses ofClassLoaderin order to extend the manner in which the Java virtual machine dynamically loads classes. Class loaders may typically be used by security managers to indicate security domains. TheClassLoaderclass uses a delegation model to search for classes and resources...

The Java Virtual Machine dynamically loads, links and initializes classes and interfaces. Loading is the process of finding the binary representation of a class or interface type with a particular name and creating a class or interface from that binary representation. Linking is the process of taki...
1. Introduction to Class Loaders Class loaders are responsible forloading Java classes dynamically to the JVM(Java Virtual Machine) during runtime.They’re also part of the JRE (Java Runtime Environment). Therefore, the JVM doesn’t need to know about the underlying files or file systems in ...
