Java perpetual calendar to obtain the calendar table of the month and year

This article uses Java technology to input the year and month to obtain the calendar table. The following is a code to show you:

Enter the year and month and print out the calendar table of this month. 1. January 1, 1900 is Monday 2 Calculate the number of days between the input year and 1900, and then calculate the number of days between January 1 of the current year and this month. 3 The total number of days%7 is obtained from the day of the week. Note: the minimum time in the computer is 1900. In addition, the UNIX system believes that 0:00 on January 1, 1970 is the time era. So, the years before 1900 are not tested in this program. If you are interested, you can study it yourself.

The above is the implementation process of perpetual calendar code. I hope it will help you.
