Java code to read day number and year its corresponding date

Java program to read the day number and year and showing its corresponding date.

import java.io.*;
class dayNo2date
{
 public static void main(String args[]) throws IOException
 {
 dayNo2date call = new dayNo2date();
 BufferedReader br = new BufferedReader(new
 InputStreamReader(System.in));
 // Read day no. and year
 System.out.print("Enter the Day No. : ");
 int n = Integer.parseInt(br.readLine());
 System.out.print("Enter the Year : ");
 int y = Integer.parseInt(br.readLine());
 call.toDate(n,y);
 }
 public void toDate(int n, int y)
 {
 int a[] = {31,28,31,30,31,30,31,31,30,31,30,31};
 if(y%4==0) // Check for leap year
 a[1] = 29;
 int s=0, m=0;
 // Calculate Month
 while(s<n)
 s+=a[m++];
 s-=a[m-1];
 int d = n-s; // Calculate Day
 // Print the Date
 System.out.println("\nDate = " +d +"-" +m +"-" +y);
 }
}

ALGORITHM:-

1. Accept the day no. and the year from the user.

2. Check whether it is a leap year or not.

3. Count and print the corresponding date.

4. End
