You can express the future in several ways. I will travel to Dubai after 3 month . = Nach drei Monaten gehe ich nach Dubai. Here you use the Präsens. Because it is obvious that it is the future. I will be doctor in the future . Später/In der Zukunft werde ich ein Doktor sein. Here you use the common construction for the future: the word "werden". Future I is made with werden: ich werde gehen - I will go/I am going to go. You use a pronoun (ich, du, er, sie, es) with a form of werden, followed by the infinitive form of a verb (du wirst sein, er wird essen, sie wird einen Film sehen...wir werden zusammen sein...). The Präsens is not a standard-future, but follows the pattern of many other languages. In English, you can use the present continuous for near future: This afternoon I am watching my favourite movie... The future II expresses finished actions in the future: I will have eaten the cake = Ich werde den Kuchen gegessen haben.
