How to display the correct date?

Question

Java

I am using bootstrap 4 and jsp.
There is such a thing as a datepicker.

When I enter 3/9/77 in the input field, bootstrap replaces the date with 03/09/77, and I need 03/09/0077. How to do it?

Answer 1

What is the datepicker?
maybe he needs to set the format?

$( function() {
         $( "#datepicker" ).datepicker({
                   dateFormat: "dd/MM/yyyy"
...
