You throw the exception above, the following code to can not run, so the waste code below! UNreachable, can't get the meaning of!

CodePudding user response:

the if (); Ended the if the back of the; Removed, as the following:

After multiple don't change the if () directly with statements, this format is called who expression, specifications, if behind the if there is only one statement, suggest don't break, more neat format

Directly with multiple don't change the if () statement, called guard expression, this format specifications, if behind the if only one statement, is not recommended a newline, format more neatly

understand, thank you very much against!
