Sun's JSF RI expects a renderer will send a null pointer exception if your component doesn't have a renderer.
Sun的JSFRI期望，在组件没有渲染器的时候，渲染器会发送一个空指针异常。
In this example, line 6 will cause a null pointer exception because the variable actions has not been initialized.
在这个例子中，第6行将产生一个null指针异常，因为变量actions还没有初始化。

It looks for cases where a code path will or could cause a null pointer exception, and it also looks for cases in which there is a redundant comparison to null.
它查找代码路径将会或者可能造成null指针异常的情况，它还查找对null的冗余比较的情况。
In this example, if the Map on line 1 does not contain the person named "Bob," a null pointer exception will result on line 5 when the person is asked for his name.
在这个例子中，如果第1行的Map不包括一个名为“bob”的人，那么在第5行询问person的名字时就会出现null指针异常。

In the next installment, we'll take a look at yet another very common bug pattern that manifests itself as a null-pointer exception, how to recognize it, and how to avoid it.
在下一个部分，我们将还要注视另外一个非常普遍的，也被证明是一个空指针异常的错误类型，以及怎样识别它和避免它。
Instead, the error signaled at run time would be a null-pointer exception instead of a class-cast exception.
相反，在运行时发出的错误将会是一个空指针异常而不是类强制转换异常。
Additionally, any code that traverses our lists and forgets to check for the empty case will get a NoSuchElementException, as opposed to the much-less-helpful null-pointer exception.
另外，任何阻断我们的链表以及忽略检查空例的代码将返回一个NoSuchElementException，而不是那些没什么用的空指针异常。
Unlike the dreaded null-pointer exception (which says nothing about what was expected to occur instead of the null pointer), a class-cast exception is relatively easy to debug.
与可怕的空指针异常(该异常除了报告空指针之外，对于将要发生的事情什么也不说)不同，类强制转换异常相对来说容易调试。
