Answer 1

you could use HH or KK to format hour in 24.

H Hour in day (0-23)
k Hour in day (1-24)

format you can use MM-dd-yyyy-kk-mm or MM-dd-yyyy-HH-mm .

Answer 2

Currently what have you done is working. and that will give you time in 24 hour format. change your system time to some where in afternoon and check it.

    String currDate = new SimpleDateFormat("MM-dd-yyyy-HH-mm").format(new Date());
    System.out.println(currDate);

I'm confused. It looks like your code will print in 24 hour format to me? It says here that HH represents the 24 hour format

Answer 4

HH is exactly what you need. It's 24 hour format. See SimpleDateFormat API. Change your computer time to 16:00 and try your code again to test.
