java 8 String類型轉Integer排序

public static void main(String[] args) {
    List<String> list = Arrays.asList("1", "10", "2");
    
    //正序排列
    Collections.sort(list,Comparator.comparingInt(Integer::parseInt));
    
    //直接輸出數組
    System.out.println(list);
    System.out.println("----------------------------");
    
    //遍歷輸出
    list.forEach(System.out::println);
}
