对给定的集合进行排序，代码如下。要求补全下列程序的代码，使得输出的结果为：[6, 8, 12, 24, 38, 42]。 public class Demo { public static void main(String[] args) { List<String> list = new ArrayList<String>(); Collections.addAll(list, "12", "6", "24", "38", "8", "42"); // 插入代码 System.out.println(list); } }

public static void main(String[] args) {
List<String> list = new ArrayList<String>();
Collections.addAll(list, "12", "6", "24", "38", "8", "42");
Collections.sort(list, new Comparator<String>() {
public int compare(String o1, String o2) {
return Integer.valueOf(o1) - Integer.valueOf(o2);
}
});
System.out.println(list);
}
