Java日期中的“ K”格式用于以AM / PM格式显示0-11中的小时。使用SimpleDateFormat(“ K”)获得相同的格式。
//以K格式显示小时 SimpleDateFormat simpleformat = new SimpleDateFormat("K"); String strHour = simpleformat.format(new Date()); System.out.println("Hour in K format = "+strHour);
上面,我们使用了SimpleDateFormat类,因此导入了以下包-
import java.text.SimpleDateFormat;
以下是一个例子-
import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { //显示当前日期和时间 Calendar cal = Calendar.getInstance(); SimpleDateFormat simpleformat = new SimpleDateFormat("E, dd MMM yyyy HH:mm:ss"); System.out.println("Date and time = "+simpleformat.format(cal.getTime())); //显示日期 simpleformat = new SimpleDateFormat("dd/MMMM/yyyy"); String str = simpleformat.format(new Date()); System.out.println("Current Date = "+str); //当前时间 simpleformat = new SimpleDateFormat("HH.mm.ss"); String strTime = simpleformat.format(new Date()); System.out.println("Current Time = "+strTime); //以K格式显示小时 simpleformat = new SimpleDateFormat("K"); String strHour = simpleformat.format(new Date()); System.out.println("Hour in K format = "+strHour); } }
输出结果
Date and time = Mon, 26 Nov 2018 10:19:28 Current Date = 26/November/2018 Current Time = 10.19.28 Hour in K format = 10
