Transferring object data from one activity to another activity

Question

I am having a class EmployeeInfo as the following:

 public class EmployeeInfo {
        private int id; // Employee ID
        private String name; // Employ         


        

Answer 1

You can simply let your EmployeeInfo class implement Serializable. Or you can send data like this

intent.putExtra("id", employInfo.getEmployeeID());
intent.putExtra("name", employInfo.getEmployeeName());
intent.putExtra("age", employInfo.getAge());

If you need to transfer a list of your custom classes, i'd use the first approach. So you would be able to put entire list as Serializable.
However they said that everyone should use Parcelable instead because it's "way faster". Tbh, I'd never used it, because it needs more effort and I doubt somebody can realize the difference in speed in a regular application w/o a load of data sending via intent
