Java Collection - 如何将Set转换为List

 
import java.util.ArrayList;
import java.util.Date;
import java.util.HashSet;
import java.util.List;
import java.util.Set;

public class Main {
  public static void main(String[] args) {
    Set<Object> set = new HashSet<Object>();
    set.add("A");
    set.add(new Long(10));
    set.add(new Date());

    List<Object> list = new ArrayList<Object>(set);
    for (int i = 0; i < list.size(); i++) {
      Object o = list.get(i);
      System.out.println("Object = " + o);
    }
  }
}
