Java million Almanac, get the calendar table _android

This article applies java technology to enter the year and month to get the calendar, the following is a piece of code to show you:

Enter the year and month and print out the calendar for this month
1.19 years, January 1, Monday.
2. Calculate input year distance 1900 how many days before the month of January 1
3. Total days%7 come from the beginning of the week
Note: The computer has a minimum of time until 1900, and the UNIX system considers January 1, 1970 0 o'clock to be the time era.
So, in this program did not test the year 1900 years ago. Interested can be studied under their own.

Import Java.util.Scanner;
 Class calender{public static void Main (string[] args) {print ();
 ///print output public static void print () {Scanner sc = new Scanner (system.in);
 System.out.println ("Please enter Year:");
 int year = Sc.nextint ();
 System.out.println ("Please enter the month (1~12):");
 int month = Sc.nextint (); int day = GetDays (year, month);//getdays method details please look down//days+1:day is the total number of days, the total number of days to enter the month is only the number of days before this month,//plus 1 becomes the first day of this month int week = days
 %7==0?1:days%7+1;//the first day of the week is the number of weeks System.out.println ("day \ t two \ t three \ t four \ t five \ t six");
 Output first row (first week) empty part for (int i=1; i<=week; i++) {System.out.print ("T");
 //Output The first line (first week) for each day for (int i=1; i<=7-week; i++) {System.out.print (i+ "\ t");
 } System.out.println ();
 Month days of January-December int monthday = 0;
   Switch (month) {case 2:if (year%4==0&&year%100!=0 | | year%400==0) {monthday=29;
   }else{monthday=28;
  } break;
   Case 4:case 6:case 9:case 11:monthday=30;
  Break
   default:monthday=31;
  Break //Output The remaining date, starting from the second week, so is 8-week for (int i=8-week; i<=monthday;
  i++) {System.out.print (i+ "T");
  Every seven days, when the date is divisible by 7, the line if ((I+week)%7==0) {System.out.println () is changed; }/* To calculate the total number of days from 1900 to 1.1 for the current month./public static int getdays (int years, int month) {//Judge the year is a leap years or excepting, get the total number of years int day1=0
 , day2=0;
  for (int i=1900; i<year; i++) {if (i%4==0&&i%100!=0 | | i%400==0) {day1+=366;
  }else{day1+=365;  The total number of days for the month for (int i=1; i<month; i++) {switch (i) {case 2:if (year%4==0&&year%100!=0 | | year%400==0
   ) {day2+=29;
   }else{day2+=28;
  } break;
   Case 4:case 6:case 9:case 11:day2+=30;
  Break
   default:day2+=31;
  Break
 } return day1+day2;

 }
 }

The above is the Calendar code implementation process, I hope to help you.
