About Question enthuware.ocpjp.v7.2.1211 :

[ETS User]

"the Path objects that we are checking contain the complete path including directories (such as c:\works\pathtest\a.java and not just a.java)" --> should *.java match against the full directory path c:\works\pathtest\a.java ?

[admin]

No, that's what the explanation explains. Can you please let me know what is not clear about it?

HTH,
Paul.

i think *.java should be matched to "c:\works\pathtest\a.java" (c:\works\pathtest\a.java = *.java). So the answer should return 1 result (instead of 0).

[admin]

Please read the explanation. It explains why *.java doesn't match "c:\works\pathtest\a.java". You may also run the given code and verify.

HTH,

BTW, if the code were like that, the result would be different... That's what the author has mentioned at the last line.

Code: Select all

void check(Path p) {
         Path name = p.getFileName();
         if(name != null && name.matches(p)){
             count++;     
         }
}

Interesting, I just checked this and the reason you get a complete path is because the string pass to Paths.get() is an absolute path, therefore the argument to walkFileTree is an absolute Path object. If you pass a relative path to Paths.get eg "" you are passing a relative Path object to walkFileTree therefore * will match files in the working directory.

In the explanation part it should be likely p.getFileName() and not p.getFileName(p)

[admin]

You are right. Fixed.
thank you for your feedback!
