Help with exercise in android studio?

What happens is that in this exercise, I have to enter an hour of entry to each specific query (either with a doctor of general medicine, dentist, dermatologist, etc.), after that I have to add the minutes that I Delay in each query and the result of that sum will give me the time of departure, in this code I do not understand why I have it bad.

I get an error in the line of dtDate=format.parse(edt1.getText()); does not recognize the parse, it comes out in red

Unknown class: 'dtDate', Can not resolve symbol 'parse', Can not resolve symbol 'getText'

These are the 3 errors that appear on this line.
