Storing the time in Java

Question

I am fresh new student in programming and I'd like to know how to store the time with PM or AM. For example the user may enter the next time : 10:45 PM

Then 10 will be stored in a variable hh , 45 in mm and PM in aa for example. Here is my code that I have try

String a = sc.next();

String [] b = a.split(":");
String [] c = a.split(" ");

int hh = Integer.parseInt(b[0]);
int mm = Integer.parseInt(b[1]);
String aa = c[1];

System.out.println(aa);

As assylias said you should maybe take a look at LocalTime . And using a homemade DateTimeFormatter in order to format your desired input String.

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("hh:mm a");
LocalTime localTime = LocalTime.parse("10:45 pm", formatter);
int hh = localTime.getHour(); 
// int hh = localTime.get(ChronoField.HOUR_OF_AMPM); // To get 10 instead of 22 for example (see comments)
int mm = localTime.getMinute();
String aa = localTime.get(ChronoField.AMPM_OF_DAY) == 0 ? "AM" : "PM";
// String aa = localTime.isBefore(LocalTime.NOON) ? "AM":"PM";

But however if you really want the user to input the time, always following the same format you can do do the following :

String a = sc.next();

String [] b = a.split(":");
String [] c = b.split(" ");

int hh = Integer.parseInt(b[0]);
int mm = Integer.parseInt(c[0]);
String aa = c[1];

Using your code.
