I need to check if some files exist in a directory using Java but the file name have a pattern. For example the file name is recap_data_03082017.txt and the numbers at the end are always changing. Is there a way to perform a search using a wildcard like recap_data_*.csv
If you are using Java 8, you could try the following,
try (Stream<Path> paths = Files.walk(Paths.get("/your/path/"), 1)) {
return paths
.filter(Files::isRegularFile)
.anyMatch(f -> {
final String fileName = f.getFileName().toString();
return fileName.startsWith("ecap_data_") && fileName.endsWith(".csv");
});
} catch (IOException e) {
e.printStackTrace();
}
