方法详细资料

loadClass

public final Class<?> loadClass(String name,
                                boolean resolve)
                         throws ClassNotFoundException

覆盖:

loadClass 在类中 ClassLoader

抛出:

ClassNotFoundException

loadClassWithoutExceptionHandling

protected Class<?> loadClassWithoutExceptionHandling(String name,
                                                     boolean resolve)
                                              throws ClassNotFoundException

Same as loadClass(String, boolean) but without exception handling.

Extending concrete class loaders should implement this instead of loadClass(String, boolean).

抛出:

ClassNotFoundException
