Hi Guys
I need to Learn Apex  thoroughly so i want to do pratice apex problems can any one please give me the apex real time requirements.its more helpfull to me

I have to remove javascript buttons to adapt it to lightning experience (LE).
I have created a custom button to create a new record, and like the new record has to receive some values from the related one, I do it with url hack, as the js button did it.
The button run perfect in classic, sending the values to the new record, but in LE the create record page opens, but not shows none of the sended values from the related record.
There exists some form to do it?
I know I would should use a quick action to create the new record in LE, but in some cases I need to change the values passed in function of the values of the related record, and I don´t know if this is possible with quick actions (ex: the record type of the new record depends of the profile of the user who creates it).
