The withMonth() method of LocalDate class in Java returns a copy of this LocalDate with the month-of-year altered.
Syntax:
public LocalDate withMonth(int month)
Parameter: This method accepts a mandatory parameter month which specifies the month-of-year to set in the result, from 1 i.e., January to 12 i.e., December.
Returns: The function returns a LocalDate based on this date with the requested month, not null.
Exceptions: The function throws a DateTimeException when the month-of-year value is invalid.
Below programs illustrate the LocalDate.withMonth() method:
Program 1:
import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
LocalDate dt1 = LocalDate.parse("2018-12-07");
LocalDate result = dt1.withMonth(01);
System.out.println("The date with month is: " + result);
}
}
|
Output:
The date with month is: 2018-01-07
Program 2:
import java.util.*;
import java.time.*;
import java.time.temporal.ChronoField;
public class GfG {
public static void main(String[] args)
{
try {
LocalDate dt1 = LocalDate.parse("2018-12-07");
LocalDate result = dt1.withMonth(13);
System.out.println("The date with month is: " + result);
}
catch (Exception e) {
System.out.println(e);
}
}
}

Output:
java.time.DateTimeException: Invalid value for MonthOfYear (valid values 1 - 12): 13
