How to Use Java to Get the Current Date and Format it

Using Java to get the current date and then formatting it to your desired output is a common task in many applications. In this article, we will show you how to use Java's built-in Date class and SimpleDateFormat class to achieve this.

Firstly, we need to create a Date object to represent the current date and time. This can be done by calling the no-argument constructor of the Date class, which initializes the object with the current date and time.

Date currentDate = new Date();

Next, we need to use the SimpleDateFormat class to format the date according to our specification. This class provides a method called 'format' which takes a Date object and a string representing the desired format. The string contains placeholder symbols that are replaced by the corresponding date and time values. For example, the symbol "yyyy" represents the year, "MM" represents the month, and "dd" represents the day.

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");

String formattedDate = formatter.format(currentDate);

System.out.println(formattedDate);

The above code will format the current date in the format "yyyy-MM-dd" and store the result in the 'formattedDate' variable. Finally, we print the formatted date to the console.

In conclusion, using Java to get the current date and format it according to our needs is easy with the Date and SimpleDateFormat classes. By understanding the symbols used in the format string, we can customize the output to our specific requirements.
