  • You need to implement explicit constructors when you need to use them. – Manu Sep 11 '15 at 14:03

This article explains the full story. In short: you need explicit constructors if you want to pass parameters to this constructor. If you do not need this, you can either provide a "parameterless" constructor ( public Foo() {} ), or you do nothing, in which case the system will create an empty one for you in the background.
