Overview

List is a data-type which can hold a collection of values. Each value present in the list is called an element.

A list can contain elements of different types say number, text, date etc. grouped together. You can also restrict the list to only accept values of a specific data-type using special qualifiers. In general, a list provides methods to store, retrieve and manipulate an aggregate of elements.

The limit to the number of elements that can be added depends on the method of addition:

• Assigning the elements directly - No limit
• Using the add builtin function - No limit (they need to be added one by one)
• Using the addAll builtin function - 25,000 elements

Example

Elements in a list can be subject to various operations such as:

• Positional Access - Manipulate elements based on their numerical positional in the list. For example, functions such as contains(), get(), and remove().
• Search - Search for elements in a list and return their numeric position. For example functions like indexOf(), lastIndexOf().
• Range - Perform range operations like sublist().
• Unique functions - Perform unique functions like intersect(), sort(), etc.
