What does this block of code do?

Question

I\'m not quite sure what this means or whats it doing, Could some one elaborate?

Player player = (Player) sender;

Answer 1

this is a simple java typecast...

is this in a bukkit minecraft server plugin? if it is, what it does is typecast the player sending the command to a Player object. Player Objects are used to target specific players in code. the player object will have the name of the player who sent the command.
