loadClass

public final Class loadClass(String name,

Description copied from class: PreferredClassLoader

Loads a class with the specified name.

PreferredClassLoader implements this method as follows:

This method first invokes findLoadedClass with name; if findLoadedClass returns a non-null Class, then this method returns that Class.

Otherwise, this method invokes isPreferredResource with name as the first argument and true as the second argument:

• If isPreferredResource throws an IOException, then this method throws a ClassNotFoundException containing the IOException as its cause.
• If isPreferredResource returns true, then this method invokes findClass with name. If findClass throws an exception, then this method throws that exception. Otherwise, this method returns the Class returned by findClass, and if resolve is true, resolveClass is invoked with the Class before returning.
• If isPreferredResource returns false, then this method invokes the superclass implementation of loadClass with name and resolve and returns the result. If the superclass's loadClass throws an exception, then this method throws that exception.

Overrides:

loadClass in class PreferredClassLoader

Parameters:

name - the binary name of the class to load

resolve - if true, then resolveClass will be invoked with the loaded class before returning

Returns:

the loaded class

Throws:

ClassNotFoundException - if the class could not be found
