java - How to load huge data into array list or any other data structure? -


i have 5000 10000 records in sqlite database , load memory (arraylist/hashmap etc). data structure suitable load huge amounts of data , access in android.

in order access 1000's of records randomly , in android use hashmap allow constant time access of data, in addition can use additional data structure objects create indexes. example, if you're data stored in hashmap<int, passenger> data , need sort passengers surname can use sqlite create list of passenger id's , access data loaded data object. if ordering not important index can still use arraylist, hashset if you're index id's needs guaranteed unique.
