Java中List转换为数组,数组转List

2019-09-26 09:55:43

List转换为Array可以这样处理：

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

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

list.toArray(strings);

反过来，如果要将数组转成List怎么办呢？如下：

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

    CORS: credentials mode is 'include'

    XMLHttpRequest cannot load http://localhost/Foo.API/token. The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://localhost:5000' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.
