Accessing the null pointer is very dangerous, as it might crash your program.
访问空指针是非常危险的，因为它可能使您的程序崩溃。
I said earlier that an empty list is a LinkedList containing a null pointer in both fields.
我前面说过，空链表就是两个域都包含一个空指针的LinkedList。
Furthermore, it says nothing about where in the code the null pointer was actually assigned.
此外，它并不指出在代码的何处这个空指针被赋值。
That means a reference type can have a null pointer, but a value type cannot have a null value.
这意味着引用类型可能有空指针，但是数值类型不能有空值。
This is because the compiler has to preserve the value of the null pointer through all conversions.
使用引用作为函数的参数可能比使用指针更有效率。
If times is a null pointer, the access time and the modification time are both set to the current time.
如果times是一个空指针，访问时间和修改时间被设置为当前时间。
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。
Unfortunately, many designers have still not learnt that the special null pointer or null object is an equally bad idea.
遗憾的是，许多设计者并没有认识到空指针或空对象带来的危害。
Instead of defining a separate class for empty lists, it represents empty lists by putting a null pointer in both fields.
它在两个域中都放置一个空指针来表示空链表，而不是为空链表定义一个单独的类。
On some computers, it is possible to dereference the null pointer and the result is null, permitting execution to continue.
在某些计算机上，它可能取消引用空指针，结果是空的，允许继续执行。
The system level error includes syntactical error, null pointer exception, web service timeout, database connection timeout, and so on.
系统级错误包括语法错误、空指针异常、web服务超时、数据库连接超时等。
Through pointer mapping set and fault model, it can detect null pointer dereference faults automatically and increases the testing efficiency.
通过指针映射集和故障模型，可以自动检测空指针引用内存故障，提高了测试效率。
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。
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。
Through pointer mapping sets and fault model, it can detect bad deallocation, memory leak and null pointer dereference faults automatically and increase the testing efficiency.
通过指针映射集和故障模型，可以自动检测内存释放异常、内存泄露和空指针引用等动态内存故障，提高了测试效率。
Therefore, it is easy to detect the use of a NULL pointer.
因此，很容易去检测NULL指针的使用。
Else, it goes through the binding vector array looking for a non-NULL pointer to binding handle.
否则，它循环遍历绑定向量数组，寻找非null的绑定句柄指针。
Null pointer errors are usually the result of one or more programmer assumptions being violated.
空指针错误通常是一个或多个程序员假设出错的结果。
Some types of memory access errors (like using a NULL pointer) cause a program to crash outright.
有些类型的内存访问错误 (比如使用一个NULL指示器) 将会导致一个程序完全崩溃。
Notice how like our recursive programs, the definition of a linked list also contains a base case — in this case, the NULL pointer.
注意，与我们的递归程序非常类似，链表的定义也包括一个基线条件——在这里是NULL指针。

注意，与我们的递归程序非常类似，链表的定义也包括一个基线条件 ——在这里是NULL指针。
Null pointer dereference fault is ubiquitous in the program with pointers. It is difficult to locate fault sources adopting dynamic testing method.
空指针态引用故障在使用指针的程序中是普遍存在的，采用动态测试方法进行测试难以准确定位故障源。
Since a NULL pointer terminates a list, we can also use the NULL pointer condition as a base case for many of our recursive functions on linked lists.
由于NULL指针会结束一个链表，所以我们也可以使用 NULL 指针条件作为基于链表的很多递归程序的基线条件。
