How to convert minute and hour integers to a "HHMM" time string in Java

I have two int variables as follows:

int minutes = 20;
int hours = 8;

How do I want to convert them to "HHMM" formation?

For the above, the result should be "0820".

If you only want to display "0820" you can just paste them together in a string.

String hoursMinutes = String.format("%02d", hours) + String.format("%02d", minutes);

Looks like you want it in a string which is simple. Just append them to a string.

String time = String.valueOf(hours) + String.valueOf(minutes);
if (hours < 10)
time = "0" +time;

If you just want to pad the variables to 2 digits each:

int minutes = 20;
int hours = 8;
String str = String.format("%02d%02d", hours, minutes);
System.out.println(str);

Prints:

0820

Look at this for more details.

Use Calendar class as below:

Calendar c = Calendar.getInstance();
c.set(Calendar.HOUR, hours);
c.set(Calender.MINUTE, minutes);

In case you only want to format the values, you can use:

String str = String.format("%02d%02d", hours, minutes);
