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

您可以使用Guava分割字符串，并将其转换为ArrayList。这也适用于空字符串，并返回一个空列表。

import com.google.common.base.Splitter;
import com.google.common.collect.Lists;

String commaSeparated = "item1 , item2 , item3";

// Split string into list, trimming each item and removing empty items
ArrayList<String> list = Lists.newArrayList(Splitter.on(',').trimResults().omitEmptyStrings().splitToList(commaSeparated));
System.out.println(list);

list.add("another item");
System.out.println(list);

输出如下:

[item1, item2, item3]
[item1, item2, item3, another item]

你也可以不使用番石榴使用以下方法:

  public static List<String> getStringAsList(String input) {
    if (input == null || input.trim().length() == 0) {
      return Collections.emptyList();
    }

    final String separators = "[;:,-]";
    var result =
        Splitter.on(CharMatcher.anyOf(separators))
            .trimResults()
            .omitEmptyStrings()
            .splitToList(input);

    return result;
  }

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

两个步骤:

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

你可以结合asList和split

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

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());
