I am trying to get to and from date where ToDate will have previous date and FromDate will have first date of the current month. For January it would be 1/1/2013 and so on. How to get the first date of the current month correctly? I am not able to do it.
today.add(Calendar.DAY_OF_MONTH, -1);
java.util.Date previousDay=today.getTime();
ToDate = sdfFile1.format(newjava.sql.Date(previousDay.getTime()));
today.add(Calendar.DATE, 1);
java.util.Date nextDay=today.getTime();
FromDate = sdfFile1.format(new java.sql.Date(nextDay.getTime()));
推薦答案
試試
Calendar c = Calendar.getInstance(); // this takes current date
c.set(Calendar.DAY_OF_MONTH, 1);
System.out.println(c.getTime()); // this returns java.util.Date
已更新(自 Java 8):
import java.time.LocalDate;
LocalDate todaydate = LocalDate.now();
System.out.println("Months first date in yyyy-mm-dd: " +todaydate.withDayOfMonth(1));
