Search and Sort Help

Has anyone attempted the last problem in the search and sort study folder?

I'm working on part (a) and figured out how to sort based on a Client's arrival time, but I have no idea what to do for date comparison.

Does anyone have any advice for working with dates?

• what primitive data type would work best?
• • String ("Feb 1, 2020);
  • Separate ints (int mm, int dd, int yyyy); ie) 2, 25, 2002 (I think this would work best...)
  • Using something found in the java libraries
  
  

       I'm very lost. Ill working on it again later.
