Answer 1

you can write a script to remove the loader after the page fully loaded with this code :

document.addEventListener('DOMContentLoaded', function() {
// your logic goes here
});

or with Jquery :
$( document ).ready(function() {
// your logic goes here
});

Answer 2

I still don't understand because I'm new with java

Answer 3

you should remove the loader with some code like that after the page fully loaded

document.addEventListener('DOMContentLoaded', function() {
// selecting the loader and remove it when the page fully loaded
document.querySelector(".loader").remove();
});

it will listen for an event
the event is fully loading the page
after that event occur the above code will execute
it will look for the first element with the class of loader and removes it
