Exercises Topic 10
Exercise 1. Get the current date
Solution:
import java.time.LocalDate;
public class Main {
public static void main(String[] args) {
LocalDate currentDate = LocalDate.now();
System.out.println("The current date is: " + currentDate);
}
}Exercise 2. Get the current time
Solution:
import java.time.LocalTime;
public class Main {
public static void main(String[] args) {
LocalTime currentTime = LocalTime.now();
System.out.println("The current time is: " + currentTime);
}
}Exercise 3. Get the current date and time
Solution:
import java.time.LocalDateTime;
public class Main {
public static void main(String[] args) {
LocalDateTime currentDateTime = LocalDateTime.now();
System.out.println("The current date and time is: " + currentDateTime);
}
}Exercise 4. Create a specific date
Solution:
import java.time.LocalDate;
public class Main {
public static void main(String[] args) {
LocalDate date = LocalDate.of(2024, 5, 29);
System.out.println("Specific date: " + date);
}
}Exercise 5. Create a specific time
Solution:
import java.time.LocalTime;
public class Main {
public static void main(String[] args) {
LocalTime time = LocalTime.of(14, 30, 45);
System.out.println("Specific time: " + time);
}
}Exercise 6. Add days to a date
Solution:
import java.time.LocalDate;
public class Main {
public static void main(String[] args) {
LocalDate currentDate = LocalDate.now();
LocalDate newDate = currentDate.plusDays(10);
System.out.println("Current date: " + currentDate);
System.out.println("Date after 10 days: " + newDate);
}
}Exercise 7. Subtract hours from a time
Solution:
import java.time.LocalTime;
public class Main {
public static void main(String[] args) {
LocalTime currentTime = LocalTime.now();
LocalTime newTime = currentTime.minusHours(3);
System.out.println("Current time: " + currentTime);
System.out.println("Time after subtracting 3 hours: " + newTime);
}
}Exercise 8. Compare two dates
Solution:
import java.time.LocalDate;
public class Main {
public static void main(String[] args) {
LocalDate date1 = LocalDate.of(2024, 5, 29);
LocalDate date2 = LocalDate.of(2023, 12, 25);
if (date1.isAfter(date2)) {
System.out.println(date1 + " is after " + date2);
} else if (date1.isBefore(date2)) {
System.out.println(date1 + " is before " + date2);
} else {
System.out.println(date1 + " is equal to " + date2);
}
}
}Exercise 9. Format a date
Solution:
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
public class Main {
public static void main(String[] args) {
LocalDate date = LocalDate.now();
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy");
String formattedDate = date.format(formatter);
System.out.println("Formatted date: " + formattedDate);
}
}
Exercise 10. Get the difference between two dates
Solution:
import java.time.LocalDate;
import java.time.Period;
public class Main {
public static void main(String[] args) {
LocalDate startDate = LocalDate.of(2023, 5, 1);
LocalDate endDate = LocalDate.of(2024, 5, 29);
Period difference = Period.between(startDate, endDate);
System.out.println("Difference between dates: " +
difference.getYears() + " years, " + difference.getMonths() + " months, " + difference.getDays() + " days.");
}
