Java Program to adjust LocalDate to last Day of Year with TemporalAdjusters class

Let us first set a date:

LocalDate localDate = LocalDate.of(2019, Month.FEBRUARY, 11);

Now, adjust LocalDate to last Day of year:

LocalDate day = localDate.with(TemporalAdjusters.lastDayOfYear());

Example

import java.time.LocalDate;
import java.time.Month;
import java.time.temporal.TemporalAdjusters;
public class Demo {
   public static void main(String[] args) {
      LocalDate localDate = LocalDate.of(2019, Month.FEBRUARY, 11);
      System.out.println("Current Date = "+localDate);
      System.out.println("Current Month = "+localDate.getMonth());
      LocalDate day = localDate.with(TemporalAdjusters.firstDayOfMonth());
      System.out.println("First day of month = "+day);
      day = localDate.with(TemporalAdjusters.lastDayOfMonth());
      System.out.println("Last day of month = "+day);
      day = localDate.with(TemporalAdjusters.lastDayOfYear());
      System.out.println("Last day of year = "+day);
      day = localDate.with(TemporalAdjusters.firstDayOfNextMonth());
      System.out.println("First day of next month = "+day);
   }
}

Output

Current Date = 2019-02-11
Current Month = FEBRUARY
First day of month = 2019-02-01
Last day of month = 2019-02-28
Last day of year = 2019-12-31
First day of next month = 2019-03-01
