The collection classes are Array, List, Map, Set, and Struct. The following examples contain the ways of using collections.

Best regards,
Hi, In addition to above suggestions, 'Collection classes are used to store, organize, and manipulate data in an efficient and flexible manner. Not just data (records) but objects also can be stored.

You can find lot of examples in standard code, the main use case is when you need to add multiple values/records and later iterate through the records to perform an action based on saved values.
Collection classes are used to store objects. They let you create arrays, lists, sets, maps, and structs that can hold any data type, even objects. For maximum performance, the classes are implemented in C++ (they are system classes). Collection classes were previously known as foundation classes. The collection classes are Array, List, Map, Set, and Struct.
