Below programs illustrate the TemporalAdjusters.firstDayOfMonth() method:
Program 1:
import java.time.LocalDate;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
TemporalAdjuster temporalAdjuster
= TemporalAdjusters
.firstDayOfMonth();
LocalDate localDate
= LocalDate.of( 2020 , 05 , 11 );
LocalDate firstDayOFMonth
= localDate.with(temporalAdjuster);
System.out.println( "First day for "
+ "month for localdate "
+ localDate + ": "
+ firstDayOFMonth);
}
}
|
Output:
First day for month for localdate 2020-05-11: 2020-05-01
Program 2:
import java.time.LocalDate;
import java.time.temporal.TemporalAdjuster;
import java.time.temporal.TemporalAdjusters;
public class GFG {
public static void main(String[] args)
{
TemporalAdjuster temporalAdjuster
= TemporalAdjusters
.firstDayOfMonth();
LocalDate localDate
= LocalDate.of( 2010 , 12 , 29 );
LocalDate firstDayOFMonth
= localDate.with(temporalAdjuster);
System.out.println( "First day for "
+ "month for localdate "
+ localDate + ": "
