Converting String to LocalDate object in Java [duplicate]

I want to convert date from String to LocalDate object: Starting date as String: "12/11/2022" I want to convert this String to LocalDate. I want to get LocalDate object and next use this LocalData inside if-else conditions to convert this object to String and return String. All conditions return first LocalData and next String as result: if I use this code with: date = LocalDate.parse(default)};

public String getStringDate(String timeProjection){ 
   if (timeProjection.equals("1") { 
      date = LocalDate.now();
   }
   .... 
    else {
       String default = "12/11/2022"; 
       date = LocalDate.parse(default);
    }

 command

   return date.format(DataTimeFormatter.ofPattern("dd/MM/YYYY"));

I get issue that is impossible this parse, but when I use:

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/YYYY"); 
String date = "16/08/2016"; 
LocalDate localDate = LocalDate.parse(date, formatter); 

This convertion works good. What do you think is possible create solution when I can't use twice this formatter: DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/YYYY") - first in else body, second in result command? Thanks for your help.
