How to Add Days to a Date in Java?

Adding Days to a Date in Java

The SimpleDateFormat class is a concrete implementation of the DateFormat class for formatting and parsing dates in a locale-sensitive manner. It allows the application to format date and time values consistently across different locales.

To add days to a date, we can use the add() method of the Calendar class. The add() method takes a field as the first parameter. The second parameter is the amount of the field to add to the calendar.

Here's an example of how to add 5 days to a date in Java:

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Calendar c = Calendar.getInstance();
c.setTime(new Date()); // Using today's date
c.add(Calendar.DATE, 5); // Adding 5 days
String output = sdf.format(c.getTime());
System.out.println(output);

In this example, we first create a SimpleDateFormat object. Then, we create a Calendar object and set it to the current date using the setTime() method. Next, we use the add() method to add 5 days to the calendar. Finally, we format the new date using the SimpleDateFormat object and print it out.
