how to get day from date

The following summarizes the implementation methods for obtaining a specified date in Java. For more information, seeCopy codeThe Code is as follows:Format a Date String --> Date or Data --> String SimpleDateFormat sdf = new SimpleDateFormat

Java get millisecond: system. currenttimemillis () Java get nanosecond: system. nanotime () (used to get very accurate time, recommended !) Java obtains the current date: gregoriancalendar date_1 = (gregoriancalendar) calendar. getinstance (); Java.

This is the SQL script that calculates the first day of the one month:SELECT DATEADD (mm, DATEDIFF (Mm,0,getdate ()), 0)--the first day of the monthSELECT DATEADD (mm, DATEDIFF (Mm,0,getdate ())-1, 0)-the first day of the monthSELECT DATEADD

Local Test Cases: # there can be no spaces on either side of the equal sign, before the error has been out here yesterday= ' date-d last-day +%y-%m-%d ' echo $yesterday curday= ' Date +%y-%m-%d ' echo $curday echo "Now time: ' Date ' +%y%m%d%T '"
