数组和list互转

数组转list

方法1:

String[] stringArray = { "a", "b", "c", "d", "e" };
List<String> list = Arrays.asList(stringArray);

 

方法2:

ArrayList<String> arrayList = new ArrayList<String>(Arrays.asList(stringArray));

 

方法3:

List<String> list1 = new ArrayList<String>(stringArray.length);
Collections.addAll(list1, stringArray);

 

 

list转数组

List<String> list = new ArrayList<String>();
list.add("1");
list.add("2");
list.add("3");

String[] strings = new String[list.size()];
list.toArray(strings);
