Why is this a compilation error instead of a PatternSyntaxException?


It seems to match the description -

public class PatternSyntaxException
extends IllegalArgumentException
Unchecked exception thrown to indicate a syntax error in a regular-expression pattern.

Thanks for your help!

Did you read the explanation for this option? It explains exactly why it is a compilation error.

HTH,

The question, though, asks about the "\s", so, the correct answer is "It will not compile"
