【Java】【1】String数组和List相互转换

 正文：

1，String[]转List

String[] strs = {"aa", "bb", "cc"}; //String数组

//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转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);
}
