你可以结合asList和split

Arrays.asList(CommaSeparated.split("\\s*,\\s*"))

使用Java 8流的另外两个扩展版本如下所示

List<String> stringList1 = Arrays.stream(commaSeparated.split(",")).map(String::trim).collect(Collectors.toList());
List<String> stringList2 = Stream.of(commaSeparated.split(",")).map(String::trim).collect(Collectors.toList());

List<String> items = Arrays.asList(s.split("[,\\s]+"));

这段代码会有帮助，

String myStr = "item1,item2,item3";
List myList = Arrays.asList(myStr.split(","));

在Java 8中将集合转换为逗号分隔的字符串

listOfString对象包含["A"，"B"，"C"，"D"]个元素-

listOfString.stream().map(ele->"'"+ele+"'").collect(Collectors.joining(","))

输出结果为:- ' A ', ' B ', ' C ', ' D '

和转换字符串数组到列表在Java 8

    String string[] ={"A","B","C","D"};
    List<String> listOfString = Stream.of(string).collect(Collectors.toList());

在groovy中，你可以使用tokenize(Character Token)方法:

list = str.tokenize(',')
