In order to decide when to use List, Set or Map, you need to know what are these interfaces and what functionality they provide. List in Java provides ordered and indexed collection which may contain duplicates. The Set interface provides an unordered collection of unique objects, i.e. Set...

https://softwareengineering.stackexchange.com/questions/113256/what-is-the-difference-between-btree-and-rtree-indexing BTree BTree (in fact B*Tree) is an efficient ordered key-value map. Meaning: given the key, a BTree index can quickly find a record, a BTree can be scanned in order. it's...
Set is an unordered collection, it doesn’t maintain any order. There are few implementations of Set which maintains the order such as LinkedHashSet (It maintains the elements in insertion order). 2) List allows duplicates while Set doesn’t allow duplicate elements. All the elements of a Se...
Hash is an unordered key-value map. It's even more efficient than a BTree: O(1) instead of O(log n). But it doesn't have any concept of order so it can't be used for sort operations or to fetch ranges. ...
What is the difference between Directed Graph and Undirected Graph? In a directed graph an edge is an ordered pair, where the ordered pair represents the direction of the edge that links the two vertices. On the other hand, in an undirected graph, an edge is an unordered pair, since there...
•Directed Graph:In the directed graph, each edge is defined by ordered pair of vertices. •Non-Directed Graph:In the undirected graph, each edge is defined by unordered pair of vertices •Connected graph:In the connected path, there is a path from every vertex to every other vertex. ...
