字符串切割后转为List
public void Str2List(){
String str = "1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30";
List<String> list1 = Arrays.stream(str.split(",")).collect(Collectors.toList());
List<String> list2 = Arrays.asList(str.split(","));
List<String> list3 = Splitter.on(',').splitToList(str);
List<Integer> list4 = Arrays.stream(str.split(",")).map(Integer::parseInt).collect(Collectors.toList());
System.out.println("结果1：" + list1);
System.out.println("结果2：" + list2);
System.out.println("结果3：" + list3);
System.out.println("结果4：" + list4);
