QUESTION

Comparison is done with the elements from another array of Strings
for now i'm doing it like following,
...ANSWER
Answered 2020-Oct-22 at 18:03If you know that the array is sorted, you can do binary search. If you know that you will need to access it more often, the most efficient ways should be to just insert it into a database like SQLite, MySQL or MongoDB and create an index. If you only start the program once, but search for many entries, a HashMap could do the job too. But for searching something in it once, there is no better way than linear search.
