Thrown when an application tries to load in a class through its

string name using:

当一个应用试图按以下方式使用字符串加载类时：

<ul>

<li>The <code>forName</code> method in class <code>Class</code>. Class类的forName方法。

<li>The <code>findSystemClass</code> method in class

<code>ClassLoader</code> . ClassLoader类的findSystemClass方法。

<li>The <code>loadClass</code> method in class <code>ClassLoader</code>. ClassLoader类的loadClass方法。

</ul>

but no definition for the class with the specified name could be found.

但未找到指定名称的类定义时抛出。

As of release 1.4, this exception has been retrofitted to conform to

the general purpose exception-chaining mechanism. The "optional exception

that was raised while loading the class" that may be provided at

construction time and accessed via the <A HREF="../../java/lang/ClassNotFoundException.html#getException()"><CODE>getException()</CODE></A> method is

now known as the cause, and may be accessed via the <A HREF="../../java/lang/Throwable.html#getCause()"><CODE>Throwable.getCause()</CODE></A> method, as well as the aforementioned "legacy method."

在1.4版本中，该异常已被更新以符合通常的异常链机制。在构造时提供“当载入类时，引发的可选异常”，

并且通过getException()方法存取cause，也可以通过Throwable.getCause()方法存取，和从上述方法继承一样。
