    Default How can I import data from a website to my program, or file

    Hi all,

    I want to import data from a web site (this is refresh every day), but I need only part of it, then read the necessary data from there. I tried to block it (array), but it did not work, and I've been looking for a lot of solutions, but I did not find it really good. How can I solve this?

    Thanks so much if anyone solves my problem.

    What kind of server does the website have and what protocol does it use? Many use the HTTP protocol.
    To read data from the site, send the server an HTTP Get command, read its response, parse it and save the part that you want.
    If you don't understand my answer, don't ignore it, ask a question.

    How can I save part that I want? Which command? Please a bit more help, and thereafter I can search exampels. Many thanks!

    I am a beginner
    This is a big project for a beginner and will require you to do lots of research.

    Do you know what the HTTP protocol is? Do a search and some reading to find out how it works.
    Java has several classes that you can use to use the HTTP protocol to read files from a server:
    For example: HttpURLConnection

    There are also some classes from the Apache project that would be useful, but I am not familiar with them.

    How can I save part that I want?
    I assume that the server returns an HTML page. Again you need to do some research about HTML.
    When reading the data returned by the server you will need to parse the part you want.
    Again I think the Apache project might have useful classes for that.
    If you don't understand my answer, don't ignore it, ask a question.

    I have a simple code. It can download web pages into texts. Is it not a solution if I download it and read it out there? What do you think?

    In fact I just do not know which command to use in order to read the relevant part of the html code.

    If the data is read from the server into a String, then there are methods in the String class to extract the parts that you want.

    Sorry, I haven't used that class and don't know what it does.
