import java.util.Calendar;
import java.util.Date;

public class AddDaysToCurrentDateExample {
    public static void main(String... args) {
        int numberOfDays = 7;

        // Add Number of Days to Current Date
        Date today = new Date();
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(today);
        calendar.add(Calendar.DATE, numberOfDays);
        Date newDate = calendar.getTime();

        System.out.println("Number of days: " + numberOfDays);
        System.out.println("Current Date: " + today);
        System.out.println("New Date: " + newDate);
    }
}
