cloning

Posted by Mukul on January 20, 2002 at 11:57 PM

> I have to create 10 objects in a for loop. I am considering to do it in two ways. One is explicitly create the object with new operator. The second one is to create the object with new operator once and clone it 9 times. (Of cource I will call the setXXX methods of the class to change the values after cloning). Which stategy is better? Creating 10 times with new or cloning the object.
> To make the situation clear I am putting little code too.

> for (loop:10 times) {
> x x1 = new x();
> x1.setXXX(value);
> x1.setYYY(value);
> // add object to Vector
> }

> OR

> x x1 = new x();
> x1.setXXX(value);
> x1.setYYY(value);
> // add object to Vector

> for (loop:9 times) {
> x x2 = (x)x1.clone();
> x2.setXXX(value);
> x2.setYYY(value);
> // add object to Vector
> }

> Please advise.
