This code defines a method parseArgument that appears to be part of a subclass overriding a method from its superclass. Here's what the method does step by step:

1. Method Purpose:

   • It likely processes or parses a given argument based on its key (String key) and the corresponding value (String value).

2. Key Matching:

   • A switch statement is used to check the value of the key parameter.
   • If the key matches CHECK_DATE_START, the code block for this case is executed.
   • If the key matches CHECK_DATE_END, the code block for this case is executed.

3. Parsing String to LocalDate:

   • For the CHECK_DATE_START case:
     • The value string is parsed into a LocalDate object using LocalDate.parse(value), and the result is assigned to the checkDateStart variable.
   • For the CHECK_DATE_END case:
     • Similarly, the value string is parsed into a LocalDate object and assigned to the checkDateEnd variable.

4. Purpose of Variables:

   • Based on their naming, checkDateStart and checkDateEnd are intended to store the start and end dates for a particular check or context.

5. Assumptions:

   • CHECK_DATE_START and CHECK_DATE_END are constants (possibly String values) defined elsewhere in the class or inherited from a superclass.
   • The value should follow a standard date format (such as ISO-8601) supported by LocalDate.parse.

In summary, this method processes date-related arguments. Depending on the key, it parses the input value (a date in String format) into a LocalDate object and assigns it to the appropriate variable (checkDateStart or checkDateEnd).
