Convert Time to Milliseconds
In this section, you will learn to convert Time to
seconds. An hour has 3600 seconds, a minute has sixty seconds and a millisecond is one thousand part of a second i.e. an unit for measuring the time.
Description of program:
This example helps you in converting a Time to milliseconds. Here, first of all
we have changed Hours to minutes, minutes to seconds and seconds to milliseconds
as shown below. We also want that the Time would be displayed in the form of
String so we have used a TimetoStr constructor here and we have passed time to
it. Therefore we get the following output.
import java.util.*;
import java.io.*;
public class TimeToMilli{
public String millisecondsToString(long time){
int milliseconds = (int)(time % 1000);
int seconds = (int)((time/1000) % 60);
int minutes = (int)((time/60000) % 60);
int hours = (int)((time/3600000) % 24);
String millisecondsStr = (milliseconds<10 ? "00" : (milliseconds<100 ? "0" : ""))+
milliseconds;
String secondsStr = (seconds<10 ? "0" : "")+
seconds;
String minutesStr = (minutes<10 ? "0" : "")+
minutes;
String hoursStr = (hours<10 ? "0" : "")+
hours;
return new String(hoursStr
+ ":" +
minutesStr + ":" +
secondsStr + "." +
millisecondsStr);
}
public static void main(String[] args){
long time = 200000000;
TimeToStr ts = new TimeToStr();
System.out.println(ts.millisecondsToString(time));
}
}
