1，String[]轉List
String[] strs = {"aa", "bb", "cc"}; //String數組
//方法1
List<String> list1 = Arrays.asList(strs);
//方法2
List<String> list2 = new ArrayList<String>(); Collections.addAll(list2, strs); //方法3 List<String> list3 = new ArrayList<String>(); for(String item : strs){ list3.add(item); }
2，List轉String[]
List<String> list = new ArrayList<>(); //list
list.add("a");
list.add("b"); list.add("c"); //方法1 String[] strs1 = list.toArray(new String[list.size()]); //方法2 String[] strs2 = new String[list.size()]; for(int i=0; i<list.size(); i++){ strs2[i] = list.get(i); }
