importjava.util.Calendar;publicclassGetCurrentHour{publicstaticvoidmain(String[]args){// 创建一个Calendar对象,表示当前时间Calendarcalendar=Calendar.getInstance();// 获取当前小时intcurrentHour=calendar.get(Calendar.HOUR_OF_DAY);// 打印当前小时System.out.println("当前小时:"+currentHour);}} 1. 2. 3...
通过获取Calendar实例,可以获取当前时间的小时数。 importjava.util.Calendar;publicclassGetCurrentHour{publicstaticvoidmain(String[]args){// 获取当前时间的Calendar实例Calendarcalendar=Calendar.getInstance();// 获取当前小时数inthour=calendar.get(Calendar.HOUR_OF_DAY);System.out.println("当前小时数:"+hour)...
3、通过Calendar类来获取当前时间。Calendar c = Calendar.getInstance();//可以对每个时间域单独修改 int year = c.get(Calendar.YEAR)int month = c.get(Calendar.MONTH)int date = c.get(Calendar.DATE)int hour = c.get(Calendar.HOUR_OF_DAY)int minute = c.get(Calendar.MINUTE)int seco...
public Date getCurrentHourStartTime() { Date now = new Date(); try { now = longHourSdf.parse(longHourSdf.format(now)); } catch (Exception e) { e.printStackTrace(); } return now; } /** * 获得本小时的结束时间,即2012-01-01 23:59:59 * * @return */ public Date getCurrentHourE...
public Date getCurrentDayStartTime() { Date now = new Date(); try { now = shortSdf.parse(shortSdf.format(now)); } catch (Exception e) { e.printStackTrace(); } return now; } /** * 获得本天的结束时间,即2012-01-01 23:59:59 ...
int second = calendar.get(Calendar.SECOND); System.out.println(year + “年” + month + “月” + date + “日” + hour + “时” + minute + “分” + second + “秒”); 可以对每个时间域单独修改 对时间进行加减操作等。 可灵活构建,显示格式,但速度较慢。
3.通过Util包的Calendar 获取时间,分别获取年月日时分秒 代码语言:javascript 复制 Calendar cal=Calendar.getInstance();int y=cal.get(Calendar.YEAR);int m=cal.get(Calendar.MONTH);int d=cal.get(Calendar.DATE);int h=cal.get(Calendar.HOUR_OF_DAY);int mi=cal.get(Calendar.MINUTE);int s=cal.get...
val currentDateTime = Calendar.getInstance().apply { timeZone?.let { val tzCalendar = Calendar.getInstance(it) this.set(Calendar.HOUR_OF_DAY, tzCalendar.get(Calendar.HOUR_OF_DAY)) this.set(Calendar.MINUTE, tzCalendar.get(Calendar.MINUTE)) } }.time This way you're getting time in millis...
System.out.println("秒:"+date.get(Calendar.SECOND)); //可以修改时间 //add date.add(Calendar.YEAR, -1); // 年份减1 date.add(Calendar.YEAR, +1); // 年份加1 //set date.set(Calendar.HOUR, 1);//设置时为 13点 date.set(Calendar.MINUTE, 45);//设置分为 45 ...
I have the following code in groovy to get current time in hours. def now = new Date() def time = now.getHours() but the getHour() method is deprecated. What are the disadvantages if I use this method and the what is the alternative to this method in groovy/Java ? java groovy ...
