Notes

In Apex, the isEmpty() method is used to check whether a list is empty or not. It is a convenient way to determine if a list contains any elements. The method returns a Boolean value, true if the list is empty, and false if it contains one or more elements.

Here's an example:

List<String> emptyList = new List<String>();

Boolean isEmpty = emptyList.isEmpty();

System.debug('Is the list empty? ' + isEmpty);

Output: Is the list empty? true
