Calculate Days In A Given Month

Introduction

In this article, we will explore how to solve the problem of calculating the number of days in a given month. This is a common programming task when working with dates and calendars. By following the step-by-step solution provided in this article, you will be able to determine the number of days in any given month.

Understanding the Problem

The problem involves accepting a month as input and calculating the number of days in that month. We need to account for leap years, as the number of days in February varies based on whether it is a leap year or not.

Approach

To solve this problem, we will use an if-else conditional statement to determine the number of days based on the input month. We will consider the specific cases of February in leap years and non-leap years. For the other months, we will use predefined values to determine the number of days.

Step-by-Step Solution

Step 1: Accepting User Input 

We will start by accepting the month as input from the user. You can use the Scanner class in Java to achieve this.

Step 2: Determining the Number of Days

Next, we will determine the number of days based on the input month. We will use an if-else conditional statement to handle the different cases.

Step 3: Handling February in Leap Years

For February, we need to check if the year is a leap year. If it is, the number of days will be 29; otherwise, it will be 28.

Step 4: Handling the Remaining Months

For the other months, we can use predefined values to determine the number of days. For example, January, March, May, July, August, October, and December have 31 days, while April, June, September, and November have 30 days.

Code Implementation

Now, let's put the steps into code and solve the problem:
