I need to convert minutes to hours and minutes in java. For example 260 should be 4:20. can anyone help me how to do convert it.
This question is related to
java
Here is my function for convert a second,millisecond to day,hour,minute,second
public static String millisecondToFullTime(long millisecond) {
return timeUnitToFullTime(millisecond, TimeUnit.MILLISECONDS);
}
public static String secondToFullTime(long second) {
return timeUnitToFullTime(second, TimeUnit.SECONDS);
}
public static String timeUnitToFullTime(long time, TimeUnit timeUnit) {
long day = timeUnit.toDays(time);
long hour = timeUnit.toHours(time) % 24;
long minute = timeUnit.toMinutes(time) % 60;
long second = timeUnit.toSeconds(time) % 60;
if (day > 0) {
return String.format("%dday %02d:%02d:%02d", day, hour, minute, second);
} else if (hour > 0) {
return String.format("%d:%02d:%02d", hour, minute, second);
} else if (minute > 0) {
return String.format("%d:%02d", minute, second);
} else {
return String.format("%02d", second);
}
}
Testing
public static void main(String[] args) {
System.out.println("60 => " + secondToFullTime(60));
System.out.println("101 => " + secondToFullTime(101));
System.out.println("601 => " + secondToFullTime(601));
System.out.println("7601 => " + secondToFullTime(7601));
System.out.println("36001 => " + secondToFullTime(36001));
System.out.println("86401 => " + secondToFullTime(86401));
}
Output
60 => 1:00
101 => 1:41
601 => 10:01
7601 => 2:06:41
36001 => 10:00:01
86401 => 1day 00:00:01
Hope it help
Use java.text.SimpleDateFormat to convert minute into hours and minute
SimpleDateFormat sdf = new SimpleDateFormat("mm");
try {
Date dt = sdf.parse("90");
sdf = new SimpleDateFormat("HH:mm");
System.out.println(sdf.format(dt));
} catch (ParseException e) {
e.printStackTrace();
}
It can be done like this
int totalMinutesInt = Integer.valueOf(totalMinutes.toString());
int hours = totalMinutesInt / 60;
int hoursToDisplay = hours;
if (hours > 12) {
hoursToDisplay = hoursToDisplay - 12;
}
int minutesToDisplay = totalMinutesInt - (hours * 60);
String minToDisplay = null;
if(minutesToDisplay == 0 ) minToDisplay = "00";
else if( minutesToDisplay < 10 ) minToDisplay = "0" + minutesToDisplay ;
else minToDisplay = "" + minutesToDisplay ;
String displayValue = hoursToDisplay + ":" + minToDisplay;
if (hours < 12)
displayValue = displayValue + " AM";
else
displayValue = displayValue + " PM";
return displayValue;
} catch (Exception e) {
LOGGER.error("Error while converting currency.");
}
return totalMinutes.toString();
long d1Ms=asa.getTime();
long d2Ms=asa2.getTime();
long minute = Math.abs((d1Ms-d2Ms)/60000);
int Hours = (int)minute/60;
int Minutes = (int)minute%60;
stUr.setText(Hours+":"+Minutes);
(In Kotlin) If you are going to put the answer into a TextView or something you can instead use a string resource:
<string name="time">%02d:%02d</string>
And then you can use this String resource to then set the text at run time using:
private fun setTime(time: Int) {
val hour = time / 60
val min = time % 60
main_time.text = getString(R.string.time, hour, min)
}
int mHours = t / 60; //since both are ints, you get an int
int mMinutes = t % 60;
System.out.printf("%d:%02d", "" +mHours, "" +mMinutes);
Given input in seconds you can transform to format hh:mm:ss like this :
int hours;
int minutes;
int seconds;
int formatHelper;
int input;
//formatHelper maximum value is 24 hours represented in seconds
formatHelper = input % (24*60*60);
//for example let's say format helper is 7500 seconds
hours = formatHelper/60*60;
minutes = formatHelper/60%60;
seconds = formatHelper%60;
//now operations above will give you result = 2hours : 5 minutes : 0 seconds;
I have used formatHelper since the input can be more then 86 400 seconds, which is 24 hours.
If you want total time of your input represented by hh:mm:ss, you can just avoid formatHelper.
I hope it helps.
import java.util.Scanner;
public class Time{
public static void main(String[]args){
int totMins=0;
int hours=0;
int mins=0;
Scanner sc= new Scanner(System.in);
System.out.println("Enter the time in mins: ");
totMins= sc.nextInt();
hours=(int)(totMins/60);
mins =(int)(totMins%60);
System.out.printf("%d:%d",hours,mins);
}
}
Try this code:
import java.util.Scanner;
public class BasicElement {
public static void main(String[] args){
Scanner input = new Scanner(System.in);
int hours;
System.out.print("Enter the hours to convert:");
hours =input.nextInt();
int d=hours/24;
int m=hours%24;
System.out.println(d+"days"+" "+m+"hours");
}
}
Duration.ofMinutes( 260L )
.toString()
PT4H20M
… or …
LocalTime.MIN.plus(
Duration.ofMinutes( 260L )
).toString()
04:20
DurationThe java.time classes include a pair of classes to represent spans of time. The Duration class is for hours-minutes-seconds, and Period is for years-months-days.
Duration d = Duration.ofMinutes( 260L );
Duration partsAccess each part of the Duration by calling to…Part. These methods were added in Java 9 and later.
long days = d.toDaysPart() ;
int hours = d.toHoursPart() ;
int minutes = d.toMinutesPart() ;
int seconds = d.toSecondsPart() ;
int nanos = d.toNanosPart() ;
You can then assemble your own string from those parts.
The ISO 8601 standard defines textual formats for date-time values. For spans of time unattached to the timeline, the standard format is PnYnMnDTnHnMnS. The P marks the beginning, and the T separates the years-month-days from the hours-minutes-seconds. So an hour and a half is PT1H30M.
The java.time classes use ISO 8601 formats by default for parsing and generating strings. The Duration and Period classes use this particular standard format. So simply call toString.
String output = d.toString();
PT4H20M
For alternate formatting, build your own String in Java 9 and later (not in Java 8) with the Duration::to…Part methods. Or see this Answer for using regex to manipulate the ISO 8601 formatted string.
LocalTimeI strongly suggest using the standard ISO 8601 format instead of the extremely ambiguous and confusing clock format of 04:20. But if you insist, you can get this effect by hacking with the LocalTime class. This works if your duration is not over 24 hours.
LocalTime hackUseOfClockAsDuration = LocalTime.MIN.plus( d );
String output = hackUseOfClockAsDuration.toString();
04:20
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.
Minutes mod 60 will gives hours with minutes remaining.
I use this function for my projects:
public static String minuteToTime(int minute) {
int hour = minute / 60;
minute %= 60;
String p = "AM";
if (hour >= 12) {
hour %= 12;
p = "PM";
}
if (hour == 0) {
hour = 12;
}
return (hour < 10 ? "0" + hour : hour) + ":" + (minute < 10 ? "0" + minute : minute) + " " + p;
}
You can also use the TimeUnit class. You could define
private static final String FORMAT = "%02d:%02d:%02d";can have a method like:
public static String parseTime(long milliseconds) {
return String.format(FORMAT,
TimeUnit.MILLISECONDS.toHours(milliseconds),
TimeUnit.MILLISECONDS.toMinutes(milliseconds) - TimeUnit.HOURS.toMinutes(
TimeUnit.MILLISECONDS.toHours(milliseconds)),
TimeUnit.MILLISECONDS.toSeconds(milliseconds) - TimeUnit.MINUTES.toSeconds(
TimeUnit.MILLISECONDS.toMinutes(milliseconds)));
}
