@dusk:

Q1: The callback will call when the interval has elapsed. It will call as many times as the timer runs. If you use 2 repeats (like in the example) the callback will be called twice. The first one will be called after 1 second and the second one will be called after 2 seconds. After that, the timer will be destroyed, no need for manually calling .destroy(). Please keep in mind, that Java uses Garbage Collection and if you lose the reference to the timer object, it might be destroyed too early. You will want to keep a reference to it somehow, like creating a global variable and assigning the timer to it.

Q2: There is a explosion for only a specific player and also a explosion for the world. If you look into the api documentation you can see, that the World class also contains a method called createExplosion. If you use this method, the explosion will be seen by everybody, if you use the Player's createExplosion, only the player will see it.

@OspIrAnt: It might be a bug. I will take a look at it at the weekend.
