我有一个arraylist像字符串值

ArrayList<String> datestring=new ArrayList<String>();
datestring.add("01/21/2013 @03:13 PM");
datestring.add("01/21/2013 @04:37 PM");
datestring.add("01/21/2013 @10:41 AM");
datestring.add("01/21/2013 @10:48 AM");
datestring.add("01/22/2013 @06:16 AM");
datestring.add("01/22/2013 @06:19 AM");
datestring.add("01/21/2013 @05:19 PM");
datestring.add("01/21/2013 @05:19 PM");

任何人都可以帮我整理上面的清单吗？以便根据AM和PM格式对值进行排序.
排序后的预期输出应该是

for (String s : datestring)
{
    System.out.println(s);
}

.

任何正文请告诉我如何在netbeans中创建package-info.java文件,当我尝试创建一个名为package-info的新java文件来指定包级别注释时,类名无效错误被抛出

提前致谢

我有一个数组列表wilth值

ArrayList<String> HexValues = new ArrayList<String>();

    HexValues.add("a");
    HexValues.add("b");
    HexValues.add("f");
    HexValues.add("1");
    HexValues.add("4");
    HexValues.add("0");
    HexValues.add("31");
    HexValues.add("32");
    HexValues.add("37");
    System.out.println("The content of HexValues is: " + HexValues);


    int start = HexValues.lastIndexOf("f");

    if (start != -1) {
        List<String> HexValuesEnd = HexValues.subList(start, HexValues.size());


        System.out.println("The content of HexValuesEnd before leaving is: " + HexValuesEnd);
        if (HexValuesEnd.size() > 0) {               

            HexValuesEnd.remove(1);
            HexValuesEnd.remove(2);
            HexValuesEnd.remove(3);
            System.out.println("The content of HexValuesEnd after removing values at indexes 1 ,2,3: " + HexValuesEnd);
        }
    }

输出是

The content of HexValues is: [a, b, f, …
