Why does Java allow arrays of size 0?

by

It signifies that it is empty. I.e. you can loop over it as if it had items and have no result occur:

for(int k = 0; k < strings.length; k++){
   // something
}

Thereby avoiding the need to check. If the array in question were null, an exception would occur, but in this case it just does nothing, which may be appropriate.
