JAVA Write a program that prompts the user to enter a year and the first three letters of a month name (with the first letter in uppercase) and displays the number of days in the month.

If the input for month is incorrect, display a message as shown in the following sample run.

SAMPLE RUN 1:

SAMPLE RUN 2:

Enter a year: 2016
Enter a month: Feb
Feb 2016 has 29 days

SAMPLE RUN 3:

Enter a year: 2016

Enter a month: jan

jan is not a correct month name

Class Name: Exercise04_17

Following are the code to this question:

import java.util.*;//import package for user input

public class Exercise04_17 //defining class Exercise04_17

{

public static void main(String[] as)//defining the main method  

{

int y,d=0; //defining integer variable

String m;//defining String variable

Scanner oxc=new Scanner(System.in);//creating scanner class object oxc

System.out.print("Enter a year: ");//print message

y=oxc.nextInt();//input year value which store in y variable

System.out.print("Enter a month: ");//print message

m=oxc.next();//input month value which store in m variable

if(m.equals("Jan")||m.equals("Mar")||m.equals("May")||m.equals("Jul")||m.equals("Aug")||m.equals("Oct")||m.equals("Dec"))//defining if block to check Month value

{

d=31;//assign value in d variable

}

if(m.equals("Apr")||m.equals("Jun")||m.equals("Sep")||m.equals("Nov"))//definingif block to check month value

{

d=30;//assign value in d variable

}

if(m.equals("Feb"))//defining if block to check month value is Feb

{

if(y%4==0||y%400==0)//defining if blook to check leap year

{

d=29;//assign value in d variable

}

else//else block

{  

d=28;//assign value in d variable

}

}

if(d!=0)//defining if block that check d variable value not equal to 0

{

System.out.println(m+" "+y+" has "+d+" days");//print inserted value with message

}

else//else block

{

System.out.println(m+" is not a correct month name");//print message
