[Java知识库]java list数组

List转Array

ArrayList<String> list=new ArrayList<String>();

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

list.toArray(strings);

或者

String[] dest = list.toArray(new String[0]);//new String[0]是指定返回数组的类型 System.out.println("dest: " + Arrays.toString(dest));

Array转list

String[] s = {"a","b","c"};
List list = java.util.Arrays.asList(s);

注意。如果修改数组的值也会影响list
