Hashmap is a data structure that stores key-value pairs and allows for fast retrieval of values based on keys.
Hashmap uses a hashing function to map keys to indices in an array.
It allows for constant time complexity O(1) for insertion, deletion, and retrieval operations.
Example: HashMap<String, Integer> map = new HashMap<>(); map.put("key", 123); int value = map.get("key");

Pagination in JPA allows for retrieving a subset of results from a query by specifying a limit and offset.
Use the setFirstResult() method to specify the starting index of the results to retrieve
Use the setMaxResults() method to specify the maximum number of results to retrieve
Combine setFirstResult() and setMaxResults() to implement pagination in JPA queries
