What class is the base for the List data structure in the programming language?

In Java language, the basic interface for the List data structure is the java.util.List interface.

It defines the main methods for working with ordered collections, such as adding, removing, retrieving elements by index, etc.

Implementations of this interface include:

• ArrayList — a dynamic array
• LinkedList — a doubly linked list

Example of using List:

import java.util.List;
import java.util.ArrayList;

List<String> list = new ArrayList<>();
list.add("First");
list.add("Second");
System.out.println(list.get(0)); // Will output "First"

Thus, List is an interface that defines a contract for lists in Java.
