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);
