Okay, so I'm having problems with my code. I've browsed Daniweb and couldn't find any solutions on here that work.
I'm extracting 2 sets of texts from a .xml file. The first part is a directory name(eg. "C:\work\") and the second part is the name of a file in that directory.
I concatenate the 2 strings and then test it against a filename checker.
The exception I get is this:
Exception in thread "main" java.util.regex.PatternSyntaxException: Illegal/unsupported escape sequence near index 3
C:\Thread test\P1\kk.txt
The relevant code is here(I've highlighted the line that throws the exception):
public static void main(String[] args) {
while (true) {
// Call scan() method
new ThreadStarter().scan();
}
}
void scan() {
System.out.println("starting scanning");
// Go through the list of priority Dir's first, then the normal dirs.
for (int i = 0; i < priorityDirs.length; i++) {
String used = location + priorityDirs[i];
filePickup(used, true);
}
}
public static class FilenameFilterRegex implements FilenameFilter {
String strRegex = "";
public boolean accept(File dir, String name) {
//return Pattern.matches(".*\\.(jpg|jpeg|gif|png|bmp)", name);
//if only one extension to check : "\\.jpg"
[B]return Pattern.matches(strRegex, name);[/B]
}
public void aregex(String straRegex) {
strRegex = straRegex;
//return (strRegex);
}
}
void filePickup(String dir, boolean bool) {
try {
// Scan for files
File main_dir = new File(dir);
File[] children = main_dir.listFiles();
// Checks if files were found
if (children.length > 0) {
for (int ii = 0; ii < children.length; ii++) {
// Make sure only files are scanned in, not directories, etc.
if (children[ii].isFile()) {
// Get fileName, call Threader in Threader, send fileName
String fileName = children[ii].getAbsolutePath();
FilenameFilterRegex FF = new FilenameFilterRegex();
FF.aregex(fileName);
File file = new File("");
if (FF.accept(file, fileName)) {
// Start a thread count
new Thread(new Threader(this, fileName, 1)).start();
}
}
}
}
} catch (InterruptedException ie) {
ie.printStackTrace();
}
}Can anyone please tell me what the problem is?
I don't know whats causing the error, and pasting the exception itself in Google just gives me vague answers.
If someone could clarify the problem for me I'd be extremely grateful.
