In the future perfect continuous tense, affirmative sentences are created by using the auxiliary verb “will” after the subject, then “have been“, then the present participle (base form + –ing) of the main verb, and any additional information or complements.
Here’s how to construct future perfect continuous affirmative sentences:
Structure:
Subject + will + have been + Present participle of the main verb (base form + –ing) + Complements or additional information

Usage of future perfect continuous – affirmative:
Expressing continuous action duration leading to a future point:
Used to convey the duration of a continuous action that will have been ongoing until a specified future point.
Example:
I will have been practicing the piano for two hours by the time my parents return.
Highlighting prolonged actions or efforts:
Used to emphasize actions or efforts that will have been continuing for an extended period by a certain future moment.
Example:
She will have been volunteering at the shelter for a year next week.
Discussing anticipated ongoing activities:
Can be employed to express expectations about ongoing activities that will have been taking place in the future.

A common mistake to avoid:
Avoid using the future perfect continuous tense with non-action verbs like to be, to seem, or to know. Instead, opt for the future perfect tense, formed with will + have + past participle, when referring to these verbs.
Incorrect: I will have been knowing Tom for a year by the end of the month.
Correct: I will have known Tom for a year by the end of the month.
