ありがとうございます。ほんとだｗ
Integer と 500文字くらいのString の2種類で100～100000個のデータの重複あり(35%くらい重複で大体65個前後登録になる)でやってみたら
ArrayHashSet<E> が圧倒した・・・下みたいな感じになったけど、Hashは速いなー
100個: ArrayHashSet<Integer>1[ms] --- Set.size()=66
100個: ArraySet<Integer>1[ms] --- Set.size()=66
100個: ArrayHashSet<String>1[ms] --- Set.size()=66
100個: ArraySet<String>0[ms] --- Set.size()=66
1000個: ArrayHashSet<Integer>1[ms] --- Set.size()=636
1000個: ArraySet<Integer>4[ms] --- Set.size()=636
1000個: ArrayHashSet<String>4[ms] --- Set.size()=636
1000個: ArraySet<String>7[ms] --- Set.size()=636
10000個: ArrayHashSet<Integer>1[ms] --- Set.size()=6331
10000個: ArraySet<Integer>259[ms] --- Set.size()=6331
10000個: ArrayHashSet<String>24[ms] --- Set.size()=6331
10000個: ArraySet<String>661[ms] --- Set.size()=6331
100000個: ArrayHashSet<Integer>10[ms] --- Set.size()=63071
100000個: ArraySet<Integer>23866[ms] --- Set.size()=63071
100000個: ArrayHashSet<String>222[ms] --- Set.size()=63071
100000個: ArraySet<String>131142[ms] --- Set.size()=63071
