Java Utililty Methods Second Format

Float _toSeconds(String strTime)
to Seconds

Float time = 0F;
try {
 if (strTime.endsWith("s")) {
 time = Float.parseFloat(strTime.replace("s", "")) * 1;
 } else if (strTime.endsWith("m")) {
 time = Float.parseFloat(strTime.replace("m", "")) * 60;
 } else if (strTime.endsWith("h")) {
 time = Float.parseFloat(strTime.replace("h", "")) * 60 * 60;
...

String addSecondCa(String d1, int timeSpan, String format)
add Second Ca

Date d1Date = toDate(d1, format);
long timeMili = d1Date.getTime() + timeSpan * 1000;
d1Date.setTime(timeMili);
return formatDateString(d1Date, format);

long calculateTimeInSeconds(long startTimeInMilliseconds, long endTimeInMilliseconds)
calculate Time In Seconds

long timeInSeconds = endTimeInMilliseconds - startTimeInMilliseconds;
float time = (float) timeInSeconds;
float result = time / 1000;
return (long) result;

long[] changeSecondsToTime(long seconds)
change Seconds To Time

long hour = seconds / 3600;
long minute = (seconds - hour * 3600) / 60;
long second = (seconds - hour * 3600 - minute * 60);
return new long[] { hour, minute, second };

boolean compareDate(String fistDate, String secondDate, String format)
compare Date

boolean flag = false;
Date fist = null;
Date second = null;
fist = getDateFromString(fistDate, format);
second = getDateFromString(secondDate, format);
if (fist.before(second)) {
 flag = true;
return flag;

double elapsedSeconds(long startTime)
Get the elapsed time in seconds.

return elapsedTime(startTime, System.nanoTime(), 1e9);

String elapsedSeconds2(long milli)
elapsed Seconds

double seconds = milli / 1000.;
return Double.toString(seconds);

String formatMiliSeconds(long time)
Format time interval for humans

long hours, minutes, seconds, mseconds;
mseconds = time % 1000;
time = time / 1000;
hours = time / 3600;
time = time - (hours * 3600);
minutes = time / 60;
time = time - (minutes * 60);
seconds = time;
...

String formatMilliIntervalAsSeconds(long interval)
Format a millisecond interval as number of seconds (with fracitonal part).

long seconds = interval / 1000;
long millis = interval - seconds * 1000;
StringBuilder buff = new StringBuilder();
buff.append(seconds).append(".");
buff.append(millis).append("s");
return buff.toString();

String formatMinutesSeconds(final long sourceDuration, final TimeUnit sourceUnit)
Formats the specified duration in 'mm:ss.SSS' format.

final long millis = TimeUnit.MILLISECONDS.convert(sourceDuration, sourceUnit);
final SimpleDateFormat formatter = new SimpleDateFormat("mm:ss.SSS", Locale.US);
return formatter.format(new Date(millis));
