Is the German future tense similar to the English future tense? Or is it different? Can i use it the same way as the English future tense?
Let's take a look at the different ways to talk about the future. The first form of future would be to take a sentence in the present and just add a temporal adverb which describes a point in the future, as in:
Morgen mache ich meine Hausaufgaben. | Tomorrow I do my homework.
Morgen bin ich am Hausaufgaben machen | Tomorrow I am doing my homework
The next step is the Futur I, which is formed with "werden + Infinitiv"
Morgen werde ich meine Hausaufgaben machen. | Tomorrow I will do my homework.
Morgen werde ich am Hausaufgaben machen sein. | Tomorrow I will be doing my homework.
And finally, there is Futur II, which is formed with "werden + Perfekt"
Morgen Abend werde ich meine Hausaufgaben gemacht haben. | Tomorrow evening I will have done my homework.
Morgen Abend werde ich am Hausaufgaben machen gewesen sein. | Tomorrow evening I will have been doing my homework.
So it seems that they are pretty similar and it is probably save to say, that you can use them equally.
