i am a nibble in java. i have my own efforts to get the things done. but certainly i am facing a challenge. i have a dummy program that searches for files of a particular extension(.txt) supplied as a command line argument. i am trying to make file objects of these searched file for further manipulations. but i can't understand how to do this in my code.. here is my code sample...
public class Find {
public static class Finder extends SimpleFileVisitor<Path> {
private final PathMatcher matcher;
private int numMatches = 0;
Finder(String pattern) {
matcher = FileSystems.getDefault().getPathMatcher("glob:" + pattern);
}
void find(Path file) {
Path name = file.getFileName();
if (name != null && matcher.matches(name)) {
numMatches++;
System.out.println(file);
}
}
// Prints the total number of
// matches to standard out.
void done() {
System.out.println("Matched: "+ numMatches);
}
// Invoke the pattern matching
// method on each file.
//@Override
public FileVisitResult visitFile(Path file,
BasicFileAttributes attrs) {
find(file);
return CONTINUE;
}
// Invoke the pattern matching
// method on each directory.
//@Override
public FileVisitResult preVisitDirectory(Path dir,
BasicFileAttributes attrs) {
find(dir);
return CONTINUE;
}
//@Override
public FileVisitResult visitFileFailed(Path file, IOException exc) {
System.err.println(exc);
return CONTINUE;
}
}
public static void main(String[] args) throws IOException {
Iterable<Path> root;
root = FileSystems.getDefault().getRootDirectories();
// System.out.println(name.getAbsolutePath());
for (Path startingDir : FileSystems.getDefault().getRootDirectories()) {
String pattern = args[0];
Finder finder = new Finder(pattern);
Files.walkFileTree(startingDir, finder);
}
}
}
