Java URLClassLoader and ClassLoader

Difference: In fact, in the two class loader has a little difference, is to be able to load the location of the class storage, from the JDK source is actually URLClassLoader inherited ClassLoader, that is to say URLClassLoader ClassLoader extended a bit , so it can be understood as urlclassloader function to be more points. ClassLoader can only load classes below classpath, and URLClassLoader may load classes under any path. Their inheritance relationship is as follows:

public class URLClassLoader extends Secureclassloader {}public class Secureclassloader extends ClassLoader {}

Write a small example to test:

First create a new file under Classpath and the Webroot folder in the root directory: all called Jay.properties, the content is different to show the difference.
