How to Add Days to a Date in Java: A Comprehensive Guide

Incorporating Days into Dates: A Comprehensive Guide in Java

The need to modify dates by adding days is a common requirement in various programming scenarios. Java provides robust mechanisms to manipulate dates conveniently.

Objective: To add a specified number of days to a given date in Java.

Implementation:

To achieve this, we can leverage the SimpleDateFormat class to parse the input date into the desired format. We then use the Calendar class to instantiate a Calendar object and initialize it using the parsed date. Subsequently, we employ the add method to increment the DATE field by the number of days we want to add.

Finally, the SimpleDateFormat class is once again utilized to format the modified date into the desired string representation. Here's the complete Java code:

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);

This code demonstrates the step-by-step process of adding days to a date in Java. The output will be the adjusted date in the specified format.
