Empty flag Error Mode In my last article, I explained how the use of NULL pointers in place of different basic types of data is one of the most common causes of nullpointerexception anomalies. This time, I will explain how an empty pointer instead of an exception can cause problems. In Java programs, exception situations are typically handled by throwing exceptions and capturing them at the appropriate con

code logic.runtimeexception:The runtimeexception system includes wrong type conversions, array cross-border access, and attempts to access null pointers and so on.The principle of dealing with runtimeexception is that if a runtimeexception occurs, it must be a programmer's fault. For example, you can avoid array out-of-bounds access exceptions by examining array subscripts and arrays boundaries. Other (IOException, etc.) checked exceptions are generally external errors, such as trying to read d
