我使用此代码将当前时间转换为整数格式
long x1=new Date().getTime();
int x=(int) x1;
现在我要从整数int x
中分别获取实际的日期值(年,月,日期,小时,分钟)。
我该怎么做?
谢谢(请引导我)

使用Java 8,您可以在LocalDate
中轻松进行管理 LocalDate today = LocalDate.now();
int thisYear = today.getYear();
int thisMonth = today.getMonthValue();
int thisDay = today.getDayOfMonth();
out.println(thisYear + "-" + thisMonth + "-" + thisDay);
但是当您尝试实现更高的目标(小时,分钟,秒)时,您可以转向LocalDateTime
LocalDateTime curMoment = LocalDateTime.now();
thisYear = curMoment.getYear();
thisMonth = curMoment.getMonthValue();
thisDay = curMoment.getDayOfMonth();
int thisHour = curMoment.getHour();
int thisMinute = curMoment.getMinute();
int thisSecond = curMoment.getSecond();
System.out.println(thisYear + "-" + thisMonth + "-" + thisDay + " " + thisHour + ":" + thisMinute + ":" + thisSecond);
然后输出将是:+

您可以使用System.currentTimeMillis()以毫秒为单位返回当前时间,然后可以做一些数学运算来计算小时,分钟和秒。
long totalMolilliseconds = System.currentTimeMillis();
long totalSeconds = totalMolilliseconds / 1000;
long currentSeconds = totalSeconds % 60;
long totalMinutes = totalSeconds / 60;
long currentMinutes = totalMinutes % 60;
long totalHours = totalMinutes / 60;
long currentHours = totalHours % 24;
