Java Data Type - 如何检查包含在一组字符串中

import java.util.Arrays;
import java.util.HashSet;
import java.util.List;
import java.util.Set;

public class Main {

  public static void main(final String[] args) {
    final Set<String[]> s = new HashSet<String[]>();
    final Set<List<String>> s2 = new HashSet<List<String>>();

    s.add(new String[] { "lucy", "simon" });
    s2.add(Arrays.asList(new String[] { "lucy", "simon" }));

    System.out.println(s.contains(new String[] { "lucy", "simon" })); // false
    System.out.println(s2.contains(Arrays
        .asList(new String[] { "lucy", "simon" }))); // true
  }

}
