一个使用集合的例子。

import java.util.Collections;
 ...
String commaSeparated = "item1 , item2 , item3";
ArrayList<String> items = new ArrayList<>();
Collections.addAll(items, commaSeparated.split("\\s*,\\s*"));
 ...

List commaseperated = new ArrayList();
String mylist = "item1 , item2 , item3";
mylist = Arrays.asList(myStr.trim().split(" , "));

// enter code here

两个步骤:

String [] = commaSeparated.split项目(“\ \ s * \ \ s *”); List<String> container = Arrays.asList(items);

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]+"));

ArrayList<HashMap<String, String>> mListmain = new ArrayList<HashMap<String, String>>(); 
String marray[]= mListmain.split(",");
