Sure. Iterate through the list and add things up.

I guess it depends on the type of objects contained in the list.Anyway, you will have to iterate through the elements of the list, and apply adequate operator/method for summing them.Would you tell us what causes you problem exactly ?

A for loop is more resonable:

for(int i = 0; i < myArrayList.size(); i++){

//whatever

}

If you using Java 1.5, a foreach loop is even better.

ArrayList<Integer> myArrayList = new ArrayList<Integer>();

...

for(Integer i: myArrayList){

//whatever

}
