please how can we use present prefect and present perfect continous.

[Amat]

Greeting for everybody.Thank you so much for your help in advance.
firstly, my name is amat. I do really need to improve my skills in Grammar.

I need details to explain these two tenses. I face so many difficulties in understanding them.

[Mister Micawber]

Here's a start:

Present Perfect

With verbs of state that begin in the past and lead up to and include the present To express habitual or continued action

* He has lived here for many years
* He has worn glasses all his life.

With events occurring at an indefinite or unspecified time in the past — with ever, never, before

* Have you ever been to Tokyo before?


Present Perfect Progressive

To express duration of an action that began in the past, has continued into the present, and may continue into the future

* David has been working for two hours, and he hasn't finished yet.
