How to print day of the date without using inbuilt calendar date day packages, libraries in java [closed]

manpreet Best Answer 2 years ago

In this program i want to print day of the date without using inbuilt calendar packages.. And i'm not able to get exact answer for certain dates (input date). in this i get day of the date correctly for only upto 31.12.0004. Note that it is the assessment given by my guide 5 days before still i'm not getting correct answer and I'm not supposed to use calendar packages and api's because syllabus for my course completed lists : basic array, if & else, for loops, class and objects.

import java.util.Scanner;
class calendarr
{
public static void main(String arg[])
    {
int z=0;
do{
    int id,im,iy;
    Scanner ip = new Scanner(System.in);
    System.out.print("Enter DD MM YYYY : ");
    id = ip.nextInt();
    im = ip.nextInt();
    iy = ip.nextInt();
    System.out.print("\n");

    int totalDays = 0, leapYearDays = 366, ordinaryYearDays = 365, y = iy-1,day=0;
    int totalDaysOfGivenYear,totalDaysUptoGivenMonth=0, totalDaysEntire;
    int leapYearCount = y%4, ordinaryYearCount = y - leapYearCount;
    int totalDaysUptoPreviousYear=0;
    int totalDaysUptoPreviousYearCount = (leapYearCount * leapYearDays)+(ordinaryYearCount * ordinaryYearDays);
    System.out.print("Odd Days Leap Year and Ordinary Year : "+leapYearCount+" "+ordinaryYearCount+"\n");


    String[] months = new String[] {"January","February","March","April","May","June","July","August","September","October","November","December"};
    int[] monthDates = new int[] {0,31,28,31,30,31,30,31,31,30,31,30,31};
    String[] weekDays = new String[] {"Saturday","Sunday"
                                                

                                                                                                        REPLY
                                                    
                                                
                                                


                                                    

                                                        
                                                            0
