    Post How to Download a file via FTP

    With this simple code you can download a file to your computer via FTP.

    You will need to amend the connection String if you wish to connect to a directory other than /public_html/

    import java.io.*;
    import java.net.URL;
    import java.net.URLConnection;
    public class JFTP {
         * JavaProgrammingForums.com
        public static String server = "ftp.server.com";
        public static String userName = "username";
        public static String password = "password";
        public static String fileName = "index.html";
        public static void main(String[] args) throws Exception{
        System.out.println("Connecting to FTP server...");    
        //Connection String
        URL url = new URL("ftp://"+userName+":"+password+"@"+server+"/public_html/"+fileName+";type=i");
        //URL url = new URL("ftp://"+userName+":"+password+"@"+server+"/"+fileName+";type=i");
        URLConnection con = url.openConnection();
        BufferedInputStream in = new BufferedInputStream(con.getInputStream());
        System.out.println("Downloading file.");
        //Downloads the selected file to the C drive
        FileOutputStream out = new FileOutputStream("C:\\" + fileName);
        int i = 0;
        byte[] bytesIn = new byte[1024];
        while ((i = in.read(bytesIn)) >= 0) {
            out.write(bytesIn, 0, i);
        System.out.println("File downloaded.");

    Good example. Suggest to use Apache's Common FTP library.
