A class loader is an object that is responsible for loading classes. The class ClassLoader is an abstract class. Given the binary name of a class, a class loader should attempt to locate or generate data that constitutes a definition for the class.

A ClassLoader is an object responsible for dynamically loading Java class during runtime to prevent JVM from realizing that ClassLoader is a part of the Java Runtime Environment. It makes JVM life easier . ClassLoader in Java Java ClassLoader. Java ClassLoader is an abstract class. It belongs to a java.lang package. It loads classes from different resources.

The Java ClassLoader is used to load .class files into the JVM at runtime.There are three main types of classloaders:- Bootstrap classloader (loads all the J

Introduction to ClassLoader in Java. A ClassLoader is an object responsible for dynamically loading Java class during runtime to prevent JVM from realizing that ClassLoader is a part of the Java Runtime Environment. The reason it's hard is security. Classloaders are meant to be immutable; you shouldn't be able to willy-nilly add classes to it at runtime.

The JavaTM platform contains several classes for use with JAR files. The JarRunner application consists of two classes, JarRunner and JarClassLoader.

The URLs can refer either to directories or to JAR files. JarClassLoader loads some class, resource, or native library which has identical path and present in multiple JARs from unpredictable JAR in a top JAR. The JarClassLoader does not have any specific scanning order thus making loading unpredictable. 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.

That means you can bundle your application and librarys within one jar and this class-loader will load all these jar-files. I think I came across this issue when I wrote a JarClassLoader for one of my projects. As I remember, if you have stuff like Class.getResource(String) which tries to load jar - local resource, they won't work out of the box with this JarClassLoader.

Classloaders are meant to be immutable; you shouldn't be able to willy-nilly add classes to it at runtime. I'm actually very surprised that works with the system classloader.
