- He will have walked > He‘ll have walked
- She will have walked > She‘ll have walked
- It will have walked > It‘ll have walked
- We will have walked > We‘ll have walked
- They will have walked > They‘ll have walked
For negative sentences, add ‘not’ after ‘will’. We usually contract the form with an apostrophe.
- I will not have walked > I won’t have walked
- You will not have walked > You won’t have walked
