Find the date of first Saturday of a month in Java

In this tutorial we will learn about Find the date of first Saturday of a month in Java with some cool and easy examples.

Find the date of first Saturday of a month in Java

To find the date of the first Saturday of a month in Java, you can use the `java.time` package along with some simple logic. Here’s how you can do it:

import java.time.DayOfWeek;
import java.time.LocalDate;

public class FirstSaturdayOfMonth {
    public static void main(String[] args) {
        // Define the year and month for which you want to find the first Saturday
        int year = 2024;
        int month = 6; // June

        // Create a LocalDate object representing the first day of the month
        LocalDate firstDayOfMonth = LocalDate.of(year, month, 1);

        // Find the day of the week for the first day of the month
        DayOfWeek dayOfWeek = firstDayOfMonth.getDayOfWeek();

        // Calculate the number of days to add to reach the first Saturday
        int daysToAdd = DayOfWeek.SATURDAY.getValue() - dayOfWeek.getValue();

        // Adjust if the first day of the month is already a Saturday
        if (daysToAdd < 0) {
            daysToAdd += 7;
        }

        // Calculate the date of the first Saturday of the month
        LocalDate firstSaturday = firstDayOfMonth.plusDays(daysToAdd);

        // Output the date of the first Saturday
        System.out.println("Date of the first Saturday of " + firstSaturday.getMonth() + " " + year + " is: " + firstSaturday);
    }
}

In this code:

– We define the year and month for which we want to find the first Saturday.
– We create a `LocalDate` object representing the first day of the month.
– We find the day of the week for the first day of the month.
– We calculate the number of days to add to reach the first Saturday by subtracting the day of the week of the first day from the value of `DayOfWeek.SATURDAY`.
– We adjust if the first day of the month is already a Saturday by adding 7 days to ensure we get the next Saturday.
– We calculate the date of the first Saturday by adding the calculated number of days to the first day of the month.
– Finally, we output the date of the first Saturday.

Benefits:

• Flexibility: This approach allows you to find the first Saturday of any given month and year.
• Readability: The code is concise and easy to understand.
• Accuracy: Leveraging the java.time package ensures accuracy in date calculations.

Output:

Date of the first Saturday of JUNE 2024 is: 2024-06-01
