下边是被打散的Java程序片段，你是否能够将它们重新排列成为

①a.remove(2);

②printAL(a);

③a.add(0,"zero");
   a.add(1,"one");

④public static void printAL(ArrayList<String> al) {

⑤if (a.contains("two")) {
     a.add("2.2");
  }

⑥a.add(2,"two");

⑦public static void main (String [] args) {

⑧System.out.print(element + " ");
  }
  System.out.println(" ");

⑨if (a.contains("three")) {
     a.add("four");
  }

⑩public class ArrayListMagnet {

⑪if (a.indexOf("four") !=4) {
     a.add(4,"4.2");
  }

⑫}

⑬import java.util.*;

⑭ArrayList<String> a = new ArrayList<String> (  );

⑮for (String element : al) {

⑯a.add(3,"three");
  printAL(a);
