Basic Date Range Printing
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
public class DateRangePrinter {
public static void main(String[] args) {
LocalDate startDate = LocalDate.of(2023, 1, 1);
LocalDate endDate = LocalDate.of(2023, 12, 31);
// Standard formatting
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
System.out.println("Start Date: " + startDate.format(formatter));
System.out.println("End Date: " + endDate.format(formatter));
}
}
Advanced Printing Techniques
Iterating Through Date Ranges
import java.time.LocalDate;
import java.time.Period;
public class DateRangeIterator {
public static void printDateRange(LocalDate start, LocalDate end) {
LocalDate current = start;
while (!current.isAfter(end)) {
System.out.println(current);
current = current.plus(Period.ofDays(1));
}
}
public static void main(String[] args) {
LocalDate startDate = LocalDate.of(2023, 1, 1);
LocalDate endDate = LocalDate.of(2023, 1, 10);
printDateRange(startDate, endDate);
}
}

Internationalization Considerations
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.util.Locale;
public class InternationalDatePrinter {
public static void main(String[] args) {
LocalDate date = LocalDate.now();
// Different locale formatting
DateTimeFormatter frenchFormatter =
DateTimeFormatter.ofPattern("dd MMMM yyyy", Locale.FRENCH);
System.out.println("French Format: " + date.format(frenchFormatter));
}
}
