以下示例程序旨在说明TemporalAdjusters.lastDayOfMonth()方法：
程序1:
// Java program to demonstrate
// TemporalAdjusters.lastDayOfMonth()
import java.time.LocalDate;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// get TemporalAdjuster with last day
// of the month adjuster
TemporalAdjuster temporalAdjuster
= TemporalAdjusters.lastDayOfMonth();
// using adjuster for local date-time
LocalDate localDate
= LocalDate.of(2020, 05, 11);
LocalDate lastDayOfMonth
= localDate.with(temporalAdjuster);
System.out.println("last day of the "
+ "month for localdate "
+ localDate + ":"
+ lastDayOfMonth);
}
}
输出：
last day of the month for localdate 2020-05-11:2020-05-31
程序2:
// Java program to demonstrate
// TemporalAdjusters.lastDayOfMonth() method
import java.time.LocalDate;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// get TemporalAdjuster with last day
// of the month adjuster
TemporalAdjuster temporalAdjuster
= TemporalAdjusters
.lastDayOfMonth();
// using adjuster for local date-time
LocalDate localDate
= LocalDate.of(2010, 12, 29);
LocalDate lastDayOfMonth
= localDate.with(temporalAdjuster);
System.out.println("last day of the "
+ "month for localdate "
+ localDate + ":"
+ lastDayOfMonth);
}
}
输出：
last day of the month for localdate 2010-12-29:2010-12-31
