    public static void main(String[] args) { Scanner sc = new Scanner(System.in);

        String d = sc.next();

    try {
        DateFormat df = new SimpleDateFormat("hh:mm:ssa");
        DateFormat out = new SimpleDateFormat("HH:mm:ss");
        Date date = df.parse(d);
        System.out.println(out.format(date));
    } catch (ParseException e) {
        e.printStackTrace();
    }

    sc.close();

      //in C#

          string amPmHourFormatTime = Console.ReadLine();
    System.Globalization.DateTimeFormatInfo dtFormat = new System.Globalization.DateTimeFormatInfo();
    dtFormat.ShortDatePattern = "hh:mm:sstt";
    Console.WriteLine(Convert.ToDateTime(amPmHourFormatTime, dtFormat).ToString("HH:mm:ss"));

        In c#, whe can do it even shorter:

        static void ConvertTime(string time)
{
DateTime dateTime = DateTime.ParseExact(time, "hh:mm:sstt", 
    System.Globalization.CultureInfo.InvariantCulture);

Console.WriteLine(dateTime.ToString("HH:mm:ss"));
}

          This is not algorithmic solution all work was done by author of C# not by your.

            public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    String time = in.next();
    String[] time_split = time.split(":");
    String hr = time_split[0];
    int hr_int = Integer.parseInt(hr);
    String ampm = time_split[2];
    String ampmc = Character.toString(ampm.charAt(2));
    if(ampmc.equals("P")&& hr_int!=12 ){
        int hr1= Integer.parseInt(hr)+12;
        hr=""+hr1; 
    }else if(ampmc.equals("A")&& hr_int==12){
     hr="00";
}
    System.out.println(hr+":"+time_split[1]+":"+Character.toString(ampm.charAt(0))
                       +Character.toString(ampm.charAt(1)));

}
