Displaying errors

[Arbalest]

hello i'm trying to make a calender as a practice so far it's working fine but the output is not what i wanted it to be here's the java code and the output in the screen:

//this is a calender displayer
import java.util.Scanner;
public class calendertest1 {
    public static void main(String[] args){
    Scanner input = new Scanner(System.in);
    int year=0, month;
    //input of the year
    while(year<=1800){
    System.out.print("type year : ");
    year = input.nextInt();
    }
    //input of the month
    System.out.print("type month number in here(1, 12)");
    month=input.nextInt();        
    //displaying the month's array
    bodyArray(month, year);      
    }
    //getting the month's name according to it's number
    public static String getMonthName(int month){
        String monthName="";
        switch (month){
            case 1: monthName="January"; break;
            case 2: monthName="February"; break;
            case 3: monthName="March"; break;
            case 4: monthName="April"; break;
            case 5: monthName="May"; break;
            case 6: monthName="June"; break;
            case 7: monthName="July"; break;
            case 8: monthName="August"; break;
            case 9: monthName="September"; break;
            case 10: monthName="October"; break;
            case 11: monthName="November"; break;
            case 12: monthName="December"; 
                    }
        return monthName;
    }
    //number of days per months 
    public static int getNumbersOfdays(int year, int month){
        // getting 31 days in here

        if(month==4 || month==6 || month==9 || month==11)
            return 30;
        //in here for february if it's a leap it get 29 otherwise 28
        if(month==2 )
            return isLeap(year)?29 : 28;
         return 0;
         }
    //boolean method for leap year check
    public static boolean isLeap(int year){
        return (year%4==0 && year%100 !=0)|| year%400==0;

        int total=0;

            }
            else{

            }                            
        }
        return total;
    }

        final int dayOne=3;
        int totalDays=totalNumbersOfDays(year, month);

    }
            
        
    }

p.s:i've canceled the java tag so the code becomes visible .
main problem is that it should select a day of the week for example a Thursday which mean days before should be a blank and it goes on, but the output just ignore them all like this if it's a a Thursday it will start from Monday and the date would be starting from 4th and and so on, if someone could help me with this and thx
