String str="158:378:159:379:160:383:161:388:162:390:163:391"通过“:”分割取出下标为奇数的值并排序

可以使用以下代码实现：

String str = "158:378:159:379:160:383:161:388:162:390:163:391";
String[] arr = str.split(":");
List<Integer> list = new ArrayList<>();
for (int i = 0; i < arr.length; i += 2) {
    list.add(Integer.parseInt(arr[i]));
}
Collections.sort(list);
System.out.println(list);

输出结果为：`[158, 159, 160, 161, 162, 163]`
