ArrayList does not have a well-packaged deduplication method, for example, for a ArrayList of [2, 5, 2, 3, 2, 4], I want to remove the duplicate elements,I do not want to put the statement also so long, do not want to use for the method of the loop to heavy, then you can consider the ArrayList into a temporary hashset, and then the temporary HashSet converted back to ArrayList,Because the elements inside the hashset are not repeatable! As for what is

Question: There are 12 table tennis balls, one of which is out of specification, but I do not know whether it is light or heavy. It is required that the ball be identified three times in Tianping. Method: Each ball is marked with a number ranging from 1 to 12. 1 2 3 4 vs 5 6 7 8There will be three possibilities①, 1 2 3 4> 5 6 7 8②, 1 2 3 4 = 5 6 7 8③, 1 2 3 4 2 5 8 11 vs 3 6 9 12A, 2 5 8 11> 3 6 9 12B, 2 5 8 11 = 3 6 9 12C, 2 5 8 11 The third term
