一、数组转为List

调用Arrays类的静态方法asList

1 　　static void convertArray2List() {2         String[] strs = new String[]{"hehe","haha","heihei"};3         List
     
       list = Arrays.asList(strs);4         5         System.out.println(JSON.toJSONString(list));6     } 结果 ： ["hehe","haha","heihei"]
     

 

二、List转为数组（以ArrayList为例）

①、Object[] toArray();

②、T[] toArray(T[] a);

1 　　static void convertList2Array() {2         List
     
       list = new ArrayList
      
       ();3         list.add("hehe");4         list.add("haha");5         list.add("heihei");6         String[] strs =  list.toArray(new String[]{});7         8         System.out.println(JSON.toJSONString(strs));9     } 结果 ：["hehe","haha","heihei"]
