    The first one is what you call an "enhanced for loop" which was introduced in JDK 1.5+
    


    It is more convenient way of iterating through a list. Also, you do not need to do explicit castings if you are using that. 
    


    From the performance perspective, I don't think there isn't much difference between the two.
