Java – use list Multiple use of size () or variable? (local optimization)

I have a simple function called many

In this function, I have many call list sizes (including about 10 elements):

list.size()

Is it faster for me to use temporary variables to get the size once, or is it faster to call the size () method every time?

Update: it is an ArrayList

Note: I know what I'm doing. I'm not looking for a speech about optimization and how it should or shouldn't be done I'm just looking for the answer

Solution

It depends on the implementation of the list

/**
  225        * Returns the number of elements in this list.
  226        *
  227        * @return the number of elements in this list
  228        */
  229       public int size() {
  230           return size;
  231       }
  232

Therefore, it is not important if you use local variables or call this method
