Correct behavior but not validated

Question about the task

Resolved

Hi everybody, My program works correctly, but it has not been validated because of the last requirement, I'm getting this indication but I'm sure it's already covered :

Any suggestion please? thanks a lot .

CrUD: Create, Update, Delete.

The program runs with one of the following sets of arguments:
-c name sex bd -u id name sex bd -d id -i id

Argument values:
name (String)
sex ("m" or "f")
bd (birth date in the following format: "04 15 1990")
-c (adds a person with the specified arguments to the end of allPeople; displays the id on the screen)
-u (updates the data of the person with the specified id)
-d (performs the logical deletion of the person with the specified id; replaces all of its data with null)
-i (displays information about the person with the specified id: name sex (m/f) bd (format Apr 15 1990))

The id corresponds to the index in the list.
All the people should be stored in allPeople.
Use Locale.ENGLISH as the second argument for SimpleDateFormat.

Example arguments:
-c Washington m "04 15 1990"

Example output for the -i argument:
Washington m Apr 15 1990

Requirements:

The Solution class must contain a public static List<Person> field called allPeople.
The Solution class must have a static block where two people are added to the allPeople list.
When you start the program with the -c argument, the program should add the person with the specified arguments to the end of the allPeople list and display the id (index).
When you run the program with the -u argument, the program must update the data of the person with the specified id in the allPeople list.
When you run the program with the -d argument, the program must perform the logical deletion the person with the specified id in the allPeople list.
When you run the program with the -i argument, the program should display the data about the person with the specified id in accordance with the format given in the task.

"m" : "f") + " " + new SimpleDateFormat("MMM dd yyyy", Locale.ENGLISH)); break; } } }

Thanks Thomas, I didn't pay attention to that.

In line 61 you print no date string but instead just the SimpleDateFormat object... you need to invoke format on that object and pass it the datasets date new SimpleDateFormat("MMM dd yyyy", Locale.ENGLISH).format(person.getBirthDate()) .
