Notes

In Apex, the remove(index) method is used to remove the element at a specified index from a list. The index parameter represents the position of the element you want to remove. After the removal, the list is automatically adjusted, and the indices of the remaining elements are updated.

Here's an example:

List<String> stringList = new List<String>{'apple', 'banana', 'cherry', 'date'};

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

stringList.remove(2);

System.debug('List after removal: ' + stringList);

Output:

Original List: (apple, banana, cherry, date)

List after removal: (apple, banana, date)
