Displaying calendars
1 Answer(s)      3 years and 10 months ago
Posted in : Java Interview Questions


Write a program that prompts the user to enter the year and first day of the year, and displays the calendar table for the year on the console. For example, if the user entered the year 2005, and 6 for Saturday, January 1, 2005, your program should display the calendar for each month in the year, as follows:

January 2005
Sun Mon Tue Wed Thu Fri Sat
1
2 3 4 5 6 7 8
9 10 11 12 13 14 15
16 17 18 19 20 21 22
23 24 25 26 27 28 29
30 31
...



December 2005
Sun Mon Tue Wed Thu Fri Sat
1 2 3
4 5 6 7 8 9 10
11 12 13 14 15 16 17
18 19 20 21 22 23 24
25 26 27 28 29 30 31

Hi Friend,

Try the following code:

import java.util.*;
public class DisplayCalendar{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter year: ");
int year = input.nextInt();
System.out.print("Enter first day of the year(0-6): ");
int day = input.nextInt();
for (int k=1; k<=12; k++) {
String month="";
int numOfDays=0;
switch (k)
{
case 1:
month="January ";
numOfDays=31;
break;
case 2:
month="February ";
if ((year%4 == 0 && year%100 != 0) || year%400 == 0 )
numOfDays=29;
else numOfDays=28;
break;
case 3:
month="March ";
numOfDays=31;
break;
case 4:
month="April ";
numOfDays=30;
break;
case 5:
month="May ";
numOfDays=31;
break;
case 6:
month="June ";
numOfDays=30;
break;
case 7:
month="July ";
numOfDays=31;
break;
case 8:
month="August ";
numOfDays=31;
break;
case 9:
month="September ";
numOfDays=30;
break;
case 10:
month="October ";
numOfDays=31;
break;
case 11:
month="November ";
numOfDays=30;
break;
case 12:
month="December ";
numOfDays=31;
break;
}
System.out.println(month + year);
System.out.println("Sun Mon Tue Wed Thu Fri Sat");
for (int i=1; i<=day; i++)
System.out.print(" ");
for (int j=1; j<=numOfDays; j++){
if (day%7==0 && day!=0)
System.out.println();
System.out.printf("%3d ", j);
day+=1;
}
day%=7;
System.out.print("\n\n");
}
}
}

Thanks
