How do I do a HTTP GET?

+1 vote

I want a Java program that calculates days between two dates.

  1. Type the first date (German notation; with whitespaces: "dd mm yyyy")
  2. Type the second date.
  3. The program should calculate the number of days between the two dates.

How can I include leap years and summertime?

My code:

import java.util.Calendar;
import java.util.Date;
import java.util.Scanner;

public class NewDateDifference {

    public static void main(String[] args) {

        System.out.print("Insert first date: ");
        Scanner s = new Scanner(System.in);
        String[] eingabe1 = new String[3];

        while (s.hasNext()) {
            int i = 0;
            insert1[i] = s.next();
            if (!s.hasNext()) {
                s.close();
                break;
            }
            i++;
        }

        System.out.print("Insert second date: ");
        Scanner t = new Scanner(System.in);
        String[] insert2 = new String[3];

        while (t.hasNext()) {
            int i = 0;
            insert2[i] = t.next();
            if (!t.hasNext()) {
                t.close();
                break;
            }
            i++;
        }

        Calendar cal = Calendar.getInstance();

        cal.set(Calendar.DAY_OF_MONTH, Integer.parseInt(insert1[0]));
        cal.set(Calendar.MONTH, Integer.parseInt(insert1[1]));
        cal.set

If you don't want to use external libraries, you can use URL and URLConnection classes from standard Java API.

An example looks like this:

String urlString = "http://agcnkxkbkx.lgius.ru4.gsr.awhoer.net/someAction?param1=value1&param2=value2....";
URL url = new URL(urlString);
URLConnection conn = url.openConnection();
InputStream is = conn.getInputStream();
// Do what you want with that stream
I hope this answer helps :)
