Question

How do I iterate through a directory to read *.csv files and upload them in my system in Java?

Ignore the upload part of post.

Answer 1

You can do something like this to locate all the files in your directory that have a .csv extension.

File[] files = new File(DIR_LOCATION).listFiles(new FileFilter() {
    public boolean accept(File file) {
        return file.getName().endsWith(".csv");
    }
});

Take a look at the File I/O section of the java tutorial
