Java .get()

The .get() method of the Calendar class is used to return the value of the given calendar field.

Syntax

The get(int field) is used to retrieve the value of a specific date or time field, indicated by the provided field argument.

public int get(int field)

Example 1

This example demonstrates a basic implementation of the .get function. The code acquires the present year, month, and day of the month from a Calendar instance, adjusting the month representation to account for the 0-based index.

import java.util.Calendar;

public class CalendarExample {
    public static void main(String[] args) {
        // Create a Calendar instance
        Calendar calendar = Calendar.getInstance();

        // Get the year, month, and day of the month
        int year = calendar.get(Calendar.YEAR);
        // Month values are 0-based (0 = January, 11 = December)
        int month = calendar.get(Calendar.MONTH);
        int dayOfMonth = calendar.get(Calendar.DAY_OF_MONTH);

        // Display the retrieved values
        System.out.println("Current Year: " + year);
        // Adding 1 to adjust for 0-based months
        System.out.println("Current Month: " + (month + 1));
        System.out.println("Day of the Month: " + dayOfMonth);
    }
}

Example 2

This example employs the Calendar class to set a fixed date (July 16, 2022) within a Calendar instance. It retrieves the year, month, and day of the month from the configured instance and displays them in a formatted output on the console.

import java.util.Calendar;

public class FixedDateCalendarExample {
    public static void main(String[] args) {
        // Create a Calendar instance and set it to a fixed date
        Calendar calendar = Calendar.getInstance();
        calendar.set(2022, Calendar.JULY, 16);

        // Get the year, month, and day of the month
        int year = calendar.get(Calendar.YEAR);
        int month = calendar.get(Calendar.MONTH);
        int dayOfMonth = calendar.get(Calendar.DAY_OF_MONTH);

        // Display the retrieved values
        System.out.println("Fixed Date: " + year + "-" + (month + 1) + "-" + dayOfMonth);
    }
}
