Write A Java Program To Find Number Of Days In A Month

In this Java tutorial, we will write a  Java Program to find the number of days in a month using the else if statement and the switch case with examples.

Java Program to Find Number of Days in a Month using Else If

Let’s write a java code to find the number of days in a month using the else if statement.

The total number of days in various months are :

1. January, March, May, August, October, and December = 31 Days
2. February = 28 or 29 Days
3. April, June, September, and November = 30 Days

import java.util.Scanner;

public class DaysinMonth {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int month;
		sc = new Scanner(System.in);
		
		System.out.print(" Please Enter The Month Number from 1 to 12 (1 = Jan, and 12 = Dec) : ");
		month = sc.nextInt();	
		
		if (month == 1 || month == 3 || month == 5 || month == 7 || month == 8 || month == 10 || month == 12 )
		{
			System.out.println("\n 31 Days in this Month");  	
		}
		else if ( month == 4 || month == 6 || month == 9 || month == 11 )
		{
			System.out.println("\n 30 Days in this Month");  	
		}  
		else if ( month == 2 )
		{
			System.out.println("\n Either 28 or 29 Days in this Month");  	
		} 
		else
			System.out.println("\n Please enter the Valid Number between 1 to 12");
	}
}

Java Program to Find Number of Days in a Month using Switch Case

import java.util.Scanner;

public class DaysinMonthCase {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int month;
		sc = new Scanner(System.in);
		
		System.out.print(" Please Enter The Month Number from 1 to 12 (1 = Jan, and 12 = Dec) : ");
		month = sc.nextInt();	
		
		switch(month)
		{
		  	case 1:
		  	case 3:
			case 5: 	
			case 7:
			case 8:
			case 10:
			case 12:			  	
				System.out.println("\n 31 Days in this Month");
			  	break;
			
			case 4:	
			case 6:
			case 9:
			case 11:			    	
				System.out.println("\n 30 Days in this Month");  
				break;
			
			case 2:
				System.out.println("\n Either 28 or 29 Days in this Month"); 
				break;
			
			default:		  	
				System.out.println("\n Please enter Valid Number between 1 to 12");
		  }
	}
}
