datetime-Java：使用TimeUni将秒转换为日，时，分和秒
我正在使用TimeStamp类将秒转换为Day，Hours，Minutes，Seconds。 我用下面的代码
public static void calculateTime(long seconds) {
int day = (int)TimeUnit.SECONDS.toDays(seconds);
long hours = TimeUnit.SECONDS.toHours(seconds) - TimeUnit.SECONDS.toHours(TimeUnit.SECONDS.toDays(seconds));
long minute = TimeUnit.SECONDS.toMinutes(seconds) - TimeUnit.SECONDS.toMinutes(TimeUnit.SECONDS.toHours(seconds));
long second = TimeUnit.SECONDS.toSeconds(seconds) - TimeUnit.SECONDS.toSeconds(TimeUnit.SECONDS.toMinutes(seconds));
System.out.println("Day " + day + " Hour " + hours + " Minute " + minute + " Seconds " + second);
}
但是我没有得到正确的结果。例如，当我将此方法称为calculateTime(3600)时，结果为Day 0 Hour 1 Minute 60 Seconds 3540，而不是Day 0 Hour 1 Minute 0 Seconds 0。
我的逻辑有什么问题？ 请帮我。

应该像
int day = (int)TimeUnit.SECONDS.toDays(seconds);
long hours = TimeUnit.SECONDS.toHours(seconds) - (day *24);
long minute = TimeUnit.SECONDS.toMinutes(seconds) - (TimeUnit.SECONDS.toHours(seconds)* 60);
long second = TimeUnit.SECONDS.toSeconds(seconds) - (TimeUnit.SECONDS.toMinutes(seconds) *60);
编辑说明：
日计算正确，不需要解释。
TimeUnit.SECONDS.toHours(seconds)将使您直接从秒转换为小时，而无需考虑已经计算的天数。 减去您已经拥有的天数，即天数* 24。 您现在剩下了几个小时。
分钟和秒相同。 您需要分别减去已经得到的小时和分钟。

您可以这样做，只使用TimeUnit：
public static void calculateTime(long seconds) {
int day = (int) TimeUnit.SECONDS.toDays(seconds);
long hours = TimeUnit.SECONDS.toHours(seconds) -
TimeUnit.DAYS.toHours(day);
long minute = TimeUnit.SECONDS.toMinutes(seconds) -
TimeUnit.DAYS.toMinutes(day) -
TimeUnit.HOURS.toMinutes(hours);
long second = TimeUnit.SECONDS.toSeconds(seconds) -
TimeUnit.DAYS.toSeconds(day) -
TimeUnit.HOURS.toSeconds(hours) -
TimeUnit.MINUTES.toSeconds(minute);
System.out.println("Day " + day + " Hour " + hours + " Minute " + minute + " Seconds " + second);
}
或稍短但可能不那么直观
public static void calculateTime(long seconds) {
int day = (int) TimeUnit.SECONDS.toDays(seconds);
long hours = TimeUnit.SECONDS.toHours(seconds) -
TimeUnit.DAYS.toHours(day);
long minute = TimeUnit.SECONDS.toMinutes(seconds) -
TimeUnit.HOURS.toMinutes(TimeUnit.SECONDS.toHours(seconds));
long second = TimeUnit.SECONDS.toSeconds(seconds) -
TimeUnit.MINUTES.toSeconds(TimeUnit.SECONDS.toMinutes(seconds));
System.out.println("Day " + day + " Hour " + hours + " Minute " + minute + " Seconds " + second);
}

简单方法：
public static void calculateTime(long seconds) {
long sec = seconds % 60;
long minutes = seconds % 3600 / 60;
long hours = seconds % 86400 / 3600;
long days = seconds / 86400;
System.out.println("Day " + days + " Hour " + hours + " Minute " + minutes + " Seconds " + sec);
}

这是我创建的代码：(持续3600秒，它显示“天数：0小时：1分钟：0秒：0”)
public class TimeConvert
{
public static void main(String[] args)
{
int fsec,d,h,m,s,temp=0,i;
fsec=3600;
//For Days
if(fsec>=86400)
{
temp=fsec/86400;
d=temp;
for(i=1;i<=temp;i++)
{
fsec-=86400;
}
}
else
{
d=0;
}
//For Hours
if(fsec>=3600)
{
temp=fsec/3600;
h=temp;
for(i=1;i<=temp;i++)
{
fsec-=3600;
}
}
else
{
h=0;
}
//For Minutes
if(fsec>=60)
{
temp=fsec/60;
m=temp;
for(i=1;i<=temp;i++)
{
fsec-=60;
}
}
else
{
m=0;
}
//For Seconds
if(fsec>=1)
{
s=fsec;
}
else
{
s=0;
}
System.out.println("Days:"+d+" Hours:"+h+" Minutes:"+m+" Seconds:"+s);
}
}
希望它能回答您的问题。

晚了但有帮助
以00:00:00的格式获取时间
/**
* The time in format.
*
* in The Format of 00:00:00
*/
public String getTimeInFormat(long _SECONDS)
{
if(TimeUnit.SECONDS.toHours(_SECONDS)>0)
{
return String.format("%02d:%02d:%02d",
TimeUnit.SECONDS.toHours(_SECONDS),
TimeUnit.SECONDS.toMinutes(_SECONDS) -
TimeUnit.HOURS.toMinutes(TimeUnit.SECONDS.toHours(_SECONDS)),
TimeUnit.SECONDS.toSeconds(_SECONDS) -
TimeUnit.MINUTES.toSeconds(TimeUnit.SECONDS.toMinutes(_SECONDS)));
}
else {
return String.format("%02d:%02d",
TimeUnit.SECONDS.toMinutes(_SECONDS) -
TimeUnit.HOURS.toMinutes(TimeUnit.SECONDS.toHours(_SECONDS)),
TimeUnit.SECONDS.toSeconds(_SECONDS) -
TimeUnit.MINUTES.toSeconds(TimeUnit.SECONDS.toMinutes(_SECONDS)));
}
}

试试这个
public static void calculateTime(long seconds) {
int day = (int)TimeUnit.SECONDS.toDays(seconds);
long hours = TimeUnit.SECONDS.toHours(seconds) ;
long tempSec = seconds - (TimeUnit.HOURS.toSeconds(hours) );
System.out.println("after hours calculation "+ tempSec);
long minute = TimeUnit.SECONDS.toMinutes(tempSec);
if(tempSec > TimeUnit.MINUTES.toSeconds(minute)){
tempSec = tempSec - (TimeUnit.MINUTES.toSeconds(minute) );
}else{
tempSec = TimeUnit.MINUTES.toSeconds(minute) - tempSec;
}
System.out.println("after min calculation "+ tempSec);
long second = TimeUnit.SECONDS.toSeconds(tempSec) ;
System.out.println("Day " + day + " Hour " + hours + " Minute " + minute + " Seconds " + second);
}

这是我的代码：
public static String secondsToString(TimeUnit greatestUnit, long sourceDuration, TimeUnit sourceUnit) {
int ordinal = greatestUnit.ordinal();
if(ordinal<=sourceUnit.ordinal())
return String.format("%02d", sourceDuration);
final long greatestDuration = greatestUnit.convert(sourceDuration, sourceUnit);
final long rest = sourceDuration - sourceUnit.convert(greatestDuration, greatestUnit);
return String.format("%02d:", greatestDuration) + secondsToString(TimeUnit.values()[--ordinal], rest, sourceUnit);
}
或循环
public static String secondsToStringByLoop(TimeUnit greatestUnit, long sourceDuration, TimeUnit sourceUnit) {
final StringBuffer sb = new StringBuffer();
int ordinal = greatestUnit.ordinal();
while(true){
if(ordinal<=sourceUnit.ordinal()) {
sb.append(String.format("%02d", sourceDuration));
break;
}
final long greatestDuration = greatestUnit.convert(sourceDuration, sourceUnit);
// if(greatestDuration>0 || sb.length()>0)
sb.append(String.format("%02d:", greatestDuration));
sourceDuration -= sourceUnit.convert(greatestDuration, greatestUnit);
greatestUnit = TimeUnit.values()[--ordinal];
};
return sb.toString();
}
用法示例：
String str = secondsToString(TimeUnit.DAYS, 1000, TimeUnit.SECONDS);
函数返回：“ 00：00：16：40”(天：小时：分钟：秒)
str = UnitsConverter.secondsToString(TimeUnit.DAYS, 1000, TimeUnit.MINUTES);
返回：“ 00:16:40”(天：小时：分钟)
str = UnitsConverter.secondsToString(TimeUnit.MINUTES, 1000, TimeUnit.SECONDS);
返回：“ 16:40”(分钟：秒)

public static void timeCalculator(){
Scanner input = new Scanner(System.in);
System.out.print("Enter length of time in seconds: ");
int n = input.nextInt();
int nDay = n/86400;
int nHours = (n%86400)/3600;
int nMin = ((n%86400)%3600) /60;
int nSec =(((n%86400)%3600)%60);
System.out.println();
System.out.print("That is "+ nDay+ " day(s),"+nHours+" hour(s), "+nMin+" minute(s), and "+nSec+" second(s). ");
}
