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.
