Notes

In Apex, the size() method is used to determine the number of elements in a list. It returns an integer representing the size or length of the list.

Here's an example:

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

Integer listSize = stringList.size();

System.debug('Size of the list: ' + listSize);

Output: Size of the list: 4
