Chapter: Date and Time Last Updated: 22-06-2023 14:11:02 UTC

Program:

            /* ............... START ............... */
                

import java.time.LocalDate;
import java.time.format.DateTimeFormatter;

public class AddDaysToDate {
    public static void main(String[] args) {
        // Input date in string format
        String inputDate = "2023-06-22";
        
        // Number of days to add
        int daysToAdd = 10;
        
        // Create a DateTimeFormatter to parse the input date string
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
        
        // Parse the input date string into a LocalDate object
        LocalDate date = LocalDate.parse(inputDate, formatter);
        
        // Add the specified number of days to the date
        LocalDate newDate = date.plusDays(daysToAdd);
        
        // Format the new date back to a string
        String result = newDate.format(formatter);
        
        // Print the result
        System.out.println("Original date: " + inputDate);
        System.out.println("New date after adding " + daysToAdd + " days: " + result);
    }
}

                /* ............... END ............... */
        

Output

Original date: 2023-06-22
New date after adding 10 days: 2023-07-02

Notes:

• In this program, you need to specify the input date as a string in the format "yyyy-MM-dd" and the number of days to add. The program uses the LocalDate class from the java.time package to perform the date manipulation. The DateTimeFormatter is used to parse and format the date string. The program then adds the specified number of days to the date using the plusDays() method and prints the result.
• When you run this program, it will output the original date and the new date after adding the specified number of days. For example, if you set the input date as "2023-06-22" and the number of days to add as 10, the output will be:
• Original date: 2023-06-22
• New date after adding 10 days: 2023-07-02
• Make sure to have Java 8 or above installed on your system to execute this program successfully.
