How to Create a Date Object using the Calendar Class in Java

In Java, the Calendar class can provide a flexible way to handle the dates and times. This article demonstrates how to create the Date object using the Calendar class by setting the specific date and time and converting it to the Date object and printing the exact date and time. This approach offers more control and flexibility compared to the Date class.

Steps to Create a Date Object using the Calendar class

• We can import the necessary classes like Calendar and Date classes from the java.util package.
• Create the Calendar Instance of the Calendar class using the Calendar.getInstance().
• We can set the desired year using the set method of Calendar class to set the year.
• We can set the desired year and month using the set method.
• Now, We can convert the Calendar Instance to the Date Object.
• Finally, print the Date Object.

Program to Create a Date Object using the Calendar class

Below is the Program to Create a Date Object using Calendar Class:

// Java Program to Create a Date Object
// Using the Calendar Class
import java.util.Calendar;
import java.util.Date;

// Driver Class
public class DateExample {
  	// Main Function
    public static void main(String[] args) {
        // Create a Calendar instance
        Calendar calendar = Calendar.getInstance();

        // Set the desired date and time
        calendar.set(Calendar.YEAR, 2024);
      
      	// Note: Months are zero-based in Calendar class
        calendar.set(Calendar.MONTH, Calendar.JUNE); 
        calendar.set(Calendar.DAY_OF_MONTH, 17);
        calendar.set(Calendar.HOUR_OF_DAY, 10);
        calendar.set(Calendar.MINUTE, 30);
        calendar.set(Calendar.SECOND, 0);

        // Convert Calendar to Date
        Date date = calendar.getTime();

        // Print the Date
        System.out.println("The date is: " + date);
    }
}

The date is: Mon Jun 17 10:30:00 UTC 2024

Explanation of above Code:

• Calendar calendar = Calendar.getInstance(): Create the Calendar object with the current date and time.
• calendar.set(Calendar.YEAR, 2024): It can be set the year to the 2024.
• calendar.set(Calendar.MONTH, Calendar.JUNE): Set the month to the June.
• calendar.set(Calendar.DAY_OF_MONTH, 17): Sets the day of the month to 17.
• calendar.set(Calendar.HOUR_OF_DAY, 10): Sets the hour of day to 10AM.
• calendar.set(Calendar.MINUTE, 30): Sets the minute to 30.
• calendar.set(Calendar.SECOND, 0): Sets the second to 0.
• Date date = calendar.getTime(): It can be converts the Calendar object to the Date object.

This program can demonstrates how to use the Calendar class to set the specific date and time, convert it to the Date object and then print it.
