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
}
}
}

Explanation:
Description of the code:
- In the above code, two integer variable "d and y" and one string variable "m" are declared, in which the "y and m" variable is used to input the value from the user end.
- In the y variable, we simply input the value and print its value, but in the m variable, we input the value and used to check its value by using multiple if blocks and in this, we also check leap year value, and then assign value in "d" variable.
- In the last step, we print input values with the "d" variable value.
