Find files in a folder using Java

by

What you want is File.listFiles(FileNameFilter filter).

That will give you a list of the files in the directory you want that match a certain filter.

The code will look similar to:

// your directory
File f = new File("C:\\example");
File[] matchingFiles = f.listFiles(new FilenameFilter() {
    public boolean accept(File dir, String name) {
        return name.startsWith("temp") && name.endsWith("txt");
    }
});
