Issue with wildcard directory search

Question

I am running into an issue with trying to validate the existence of a file in a directory utilizing a wildcard.

The method is supposed to determine if a file with name FAACIFP_(year)(cycle).DAT could be found in the current directory.

I've tried running a PathMaker.matches("glob:FAACIFP_18") with IF/ELSE and when I tested it, it would always evaluate TRUE. So, I tried a lambda function, and it won't find the file.

Shouldn't the lambda below print the file name, or am I misunderstanding/misusing it?

static void getCnvrtdCifpName() throws IOException{
        String cnvFileName = "FAACIFP_"+Year.now()
                .format(DateTimeFormatter.ofPattern("yy"));
        Path cnvFilePath = Paths.get(System.getProperty("user.dir"));
        Files.find(cnvFilePath,0,(path,attr) -> 
                path.getFileName().startsWith(cnvFileName)).forEach(System.out::println);
        System.out.println("EVALUATING METHOD....\t SEARCH PATH: "+cnvFilePath
                +" \n\t\t\t FILE STRING: "+cnvFileName);
    }

Output:

run:
Located RAW CIFP file FAACIFP18

EVALUATING METHOD....    SEARCH PATH: C:\Users\u314170\Documents\Personal\Java\NetBeans\A424Parser 
             FILE STRING: FAACIFP_18

Answer 1

Two problems: 1) change the maxdepth in your find call to 1 (from zero) 2) path.getFileName() returns a full pathname. You will want to evaluate only the filename portion (look at getName(getNameCount()-1)

Answer 2

After the suggestions, I finally found a resolution:

static void getCnvrtdCifpName() throws IOException{
        String cnvFileName = "FAACIFP_"+Year.now()
                .format(DateTimeFormatter.ofPattern("yy"));
        Path cnvFilePath = Paths.get(System.getProperty("user.dir"));
        DirectoryStream<Path> cnvFileStream = Files.newDirectoryStream(cnvFilePath,cnvFileName+"*");
        System.out.println("EVALUATING METHOD....\t SEARCH PATH: "+cnvFilePath
                +" \n\t\t\t FILE STRING: "+cnvFileName);
        List cnvDirList = new ArrayList();
        for(Path file: cnvFileStream){
            cnvDirList.add(file.getFileName().toString());
        }
        cnvFileStream.close();
        System.out.println(cnvDirList);
    }

With output:

run:
EVALUATING METHOD....    SEARCH PATH: C:\Users\u314170\Documents\Personal\Java\NetBeans\A424Parser 
             FILE STRING: FAACIFP_18
[FAACIFP_1808.dat, FAACIFP_1810.txt, FAACIFP_1811.txt]
BUILD SUCCESSFUL (total time: 0 seconds)

I really enjoy the problem-solving challenges while learning Java. There are so many resources out there, and many different ways to resolve an issue.
