Java中使用Arrays.asList初始化ArrayList

package xiaoling;
import java.util.Arrays;
import java.util.ArrayList;
import java.util.List;
public class ListTest{
        public static void main(String[] args){
                List<List<Integer>> list = new ArrayList<>();
                for (int num=0; num<10; ++num){
                        list.add(new ArrayList(Arrays.asList(num, num+1)));
                }
                System.out.println(list);
        }
}
