Vector.size() in Java -

-

how vector.size() work exactly, returning aleready known array.length or makes calculations every time?

my point is.. better have variable store vector's size when need use in loop example :

int vectorlength = myvector.size(); (int = 0; < vectorlength; i++) { //... }

or can use directly vector.size() ? better in terms of memory , cpu time used?

you can @ actual codes how implements it:

  308       * @return  number of components in vector   309       */   310       public synchronized int size() {   311           return elementcount;   312       }

it int value getter.
