Notes

In Apex, the clear() method is used to remove all elements from a list, leaving it empty. It's a convenient way to reset or clear the contents of a list without having to iterate through and remove each element individually.

Here's an example:

List<Integer> numberList = new List<Integer>{1, 2, 3, 4, 5};

System.debug('Original List: ' + numberList);

numberList.clear();

System.debug('List after clearing: ' + numberList);

Output Before Clear: Original List: (1, 2, 3, 4, 5)

Output After Clear: List after clearing: ()
