Introduction:

Printing a calendar of a specific month in Java involves generating and formatting the dates for that month. Java provides classes like ‘Calendar' and ‘GregorianCalendar' to handle date calculations and formatting with ‘SimpleDateFormat'.

Here’s a straightforward example to print a calendar for a given month:

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.GregorianCalendar;

public class CalendarExample {
    public static void main(String[] args) {
       
        int year = 2024;
        int month = Calendar.JULY; // Note: Calendar.JULY is 6 (0-indexed)

        Calendar calendar = new GregorianCalendar(year, month, 1);

        int daysInMonth = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);

        SimpleDateFormat sdf = new SimpleDateFormat("MMMM yyyy");
        System.out.println(sdf.format(calendar.getTime()));
        System.out.println("Sun Mon Tue Wed Thu Fri Sat");

        calendar.set(Calendar.DAY_OF_MONTH, 1);

        int dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK); // 1 = Sunday, ..., 7 = Saturday

        for (int i = 1; i < dayOfWeek; i++) {
            System.out.print("    ");
        }

        for (int day = 1; day <= daysInMonth; day++) {
           
            System.out.printf("%3d ", day);

            calendar.add(Calendar.DAY_OF_MONTH, 1);

            if (calendar.get(Calendar.DAY_OF_WEEK) == Calendar.SUNDAY) {
                System.out.println();
            }
        }

        System.out.println();
    }
}

Output:

July 2024
Sun Mon Tue Wed Thu Fri Sat
     1   2   3   4   5   6 
 7   8   9   10  11  12  13 
 14  15  16  17  18  19  20 
 21  22

• Setting up the Calendar: GregorianCalendar is used to set the year and month. We initialize it with the desired year and month (using Calendar.JULY which corresponds to month 6, as months in Java are 0-indexed).
• Getting Days in Month: calendar.getActualMaximum(Calendar.DAY_OF_MONTH) gives the number of days in the specified month.

Conclusion:

In this conclusion,  Java programming provides flexible methods and functions to print calendar month in Java.  This example prints a simple textual representation of a calendar for a specified month and year in Java. Adjustments can be made for different formats or additional features, such as highlighting the current day or including events.
