ArrayList in AP Computer Science A

numbers.length() == 0

numbers.isEmpty()

numbers.hasNoElements()

numbers.size() == -1

For (int i=0; i < values.size(); i++) {}

Do-while (values.iterator().hasNext()) {}

For (int i=values.size()-1; i >=0 ; i--) {}

While (!values.isEmpty()) {}

The condition properly uses the size() method as part of its check so as not looping beyond the list's bounds.

Relies exclusively on hard-coded numeric values instead of relying on dynamic aspects like the size of the ArrayList being iterated over.

Ensures each element is visited exactly twice to ensure thorough processing of elements within.

Only increments or skips odd indexed elements during traversal to preserve memory efficiency and application performance.

Set the loop variable to zero inside the loop body before the loop incrementation

Decrement the loop variable inside the loop body before the loop incrementation

Increment the loop variable inside the loop body before the loop incrementation

We can’t avoid an infinite loop using a regular for loop and must use an enhanced for loop instead

A programmer might prefer methods specifically designed for ArrayLists over those available through the List interface when efficiency is a concern.

Ultimately, ArrayList has more efficient implementations for certain operations than methods defined in the generic List interface.

Correct answer - explains why ArrayList is referred to as providing specific method implementations, while the List interface represents the general case that may not be optimized for a particular use case.

eliminate(i)

remove(i)

replace(i)

discard(i)

Utilize a regular for loop with a cumulative variable that adds each individual element.

Use an enhanced for loop to sum values since it provides no access to the list index.

Utilize iterator objects methods to calculate the sum by passing summation commands in each call.

Utilize a recursive method to pass through the list and cumulatively add up values.

Use enhanced for loop and remove elements directly.

Iterate over the ArrayList with a regular for loop and call remove(index) immediately.

Apply a foreach loop to remove items based on match conditions.

Utilize iterator removal method after checking with next().
