IntroductionIf you're working with dates in Java, you'll need to know how to get the day of the week. Luckily, the Java Calendar class makes this easy. In this article, we'll explore how to use the Calendar class to get the day of the week for any date in 2024.
What is the Java Calendar Class?The Java Calendar class is part of the Java standard library and provides a way to work with dates and times. It's a powerful and flexible class that can handle a wide range of use cases, from simple date calculations to complex recurring events.
How to Get the Day of the Week in Java CalendarTo get the day of the week for a specific date in 2024, you'll need to create a Calendar instance and set the date using the set() method. Then, you can use the get() method with the DAY_OF_WEEK constant to retrieve the day of the week. Here's an example:
Calendar cal = Calendar.getInstance();
cal.set(2024, Calendar.JANUARY, 1);
int dayOfWeek = cal.get(Calendar.DAY_OF_WEEK);
System.out.println("Day of week: " + dayOfWeek);
What are the Possible Values for Day of the Week?The value returned by the get() method for DAY_OF_WEEK is an integer representing the day of the week. In Java, the values range from 1 (Sunday) to 7 (Saturday). You can use this value to determine the day of the week in your application.
