In Apex, a List is a dynamic collection of elements of the same data type. Unlike arrays, lists in Apex can dynamically resize, making them more flexible for managing collections of data. Lists can hold any type of object, including other lists or custom objects.

Here's a basic overview of using lists in Apex:

You can declare and initialize a list using the following syntax:

List<DataType> listName = new List<DataType>();

You can also initialize a list with values directly:

List<String> stringList = new List<String>{'apple', 'banana', 'cherry'};
System.debug(stringList);

Output: (apple, banana, cherry)
