I am not sure what that statement means....
Array size is specified when the array is created, and this size
is always available as the length variable attached to the array object. If you have someFunction that returns a String array:
String[] ar = someFunction();
for( int i = 0 ; i < ar.length ; i++ ){
System.out.println( ar[ i ] );
}

FYI, this code throws a NullPointerException if the someFunction() returns null.

You do not say...
