For instance, an a-line Bob is styled in an Angle that frames the face.
例如,A线波波就是从显示出脸的轮廓这个角度上来造型的。
Because FindBugs doesn't know if the map contains "Bob" or not, it will flag line 5 as a possible null pointer exception.
因为FindBugs不知道map是否包含“bob”,所以它将第5行标记为可能null指针异常。
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。
