Stream流处理分隔字符串

Stream 流处理字符串—分隔字符串

1. 逗号分割字符串至list

String string = "a,b,c";
System.out.println("--------字符串以“,”切分(流处理)---------");
List<String> collect = Stream.of(string.split(",")).collect(Collectors.toList());

2. 连接字符串数组、list至使用逗号分割的字符串

List<String> asList = Arrays.asList("a", "b", "c", "d", "e");
System.out.println("---------list遍历后以“,”分隔(流模式)----------");
String collect = asList.stream().collect(Collectors.joining(","));
