How to extract .dat file from the internet using Java?

[burian]

Hi all, I am new to Java.

I want to know how to extract a list of historical stock price files (.dat format) from a particular stock website and insert the information into MySQL database using Java. I heard there is something called "HTML Parser".

Can anyone help me with it? Thanks!

HTMLParser will only work for an already "downloaded" HTML page. What you need is Http(s)URLConnection to "get" the page/file in the first place. See the API docs for either HttpURLConnection or HttpsURLConnection, whichever is applicable.

Edit: After that (i.e. what you do once you "get" it, depends on the format of the file. But guessing by the extension, it is not an html file, so HTMLParser will still not help.

ok, so lets say if I don't use HTML Parser, is there any other way that I can extract all the .dat files from a particular stock website? Thanks!

Have you even looked at the classes mentioned yet.

Use one for each of those ".dat" files, providing the complete url to it.
