Answer 1

If you use a service locator, it usually means that you explicitly ask some object to create another object for you, which is usually considered an anti-pattern. Dependency injection is the other way around.

Say you have a class called Warrior, which has a Weapon. Using the service locator, you would ask the service locator for a Weapon in the constructor of the Warrior.
Using dependency injection, the Weapon would be injected into the constructor of the Warrior, without you explicitly asking for it.
