List, Map and Set are three different data structures used in Java, so it is hard to say which one is better over the others. They are used in different purposes.
List - This datastructure is used to contain list of elements. In case you need list of elements and the list may contain duplicate values, then you have to use List.
Map - It contains data as key value pair. When you have to store data in key value pair, so that latter you can retrieve data using the key, you have to use Map data structure.
Set - It has some similarities with List, but it can't contain duplicate elements. So when you need a set of data where duplicates are not allowed, you need this data structure.
