Validating Dates

In this lesson, we will show how to validate a date field. Say, we want to store the date when the player won the last title. We will add a field lastWon to the Athlete class. This value must be in the past and must follow a specific pattern (dd-mm-yyyy). Any date value violating these constraints should result in a validation error.

We will create a Date field lastWon and generate getter and setter methods.
