Does anyone know of an easier method to format times than a bunch of if else statements?


What I mean by format for example

That was just a quick job I could care less

Basically I need to get it output a hour variable and a minute variable like such hh:mm

here is my attempt, doesn't work, I have not debugged it thoroughly yet

 @Override
    public String toString(){
        boolean pm = getHour() > 12;
        String min ="" , hour = "";
        if (getMinute() < 10){
          min = "0" + getMinute();
        } else {
            min = "" + getMinute();
        }

        if (getHour() < 10){
          hour = "0" + getHour();
        }
        if (getHour() > 12 && getHour() - 12 < 10){
          hour = "0" + (getHour() - 12);
        }
        if (getHour() > 9 && getHour() < 13){
          hour = "" + getHour();
        }
        if (pm){
          return hour + ":" + min + " PM";
        }
        return hour + ":" + min + " AM";


    }

getHour and getMinute just return a variable assigned to the class

Use the SimpleDateFormat in conjunction with the Date/Calendar class.

DateFormat df = new SimpleDateFormat("dd/MM/yyyy");   
String TheData = df.format(DateInstance);

Specify the format of the date/time you want.. Do a quick search on the formats. In C# its dd/MM/yyyy/hh:mm:ss for day/month/year/hours/minutes/seconds..
MMM for January instead of Jan.
ddd for Monday instead of Mon.
yy for 09 instead of 2009.

etc..

All I want is the hour and minute…..I don't care about the rest, simply due to the assignment note caring. Is there a way to only get the hours and seconds or should I parse the string?

At the time of me posting this reply, the code below will print 06:05:43 PM

As I suggested earlier, formatting without if-else can be done using DateFormat and passing a date to the format function of that class as shown below:

public static void main(String[] args) {
        Calendar C = Calendar.getInstance();
        DateFormat DF = new SimpleDateFormat("hh:mm:ss a");
        System.out.println(DF.format(C.getTime()));
    }
