The calendar displays the java code for reading the input year/year.

This article mainly introduces the java code for reading the input year/year from the calendar display. If you need it, refer to it.

 

The Code is as follows:

Import java. awt .*;

Import java. awt. event .*;

Import java. util. Calendar;

 

Import javax. swing. JOptionPane;

 

Class CalendarBean {// defines a calendar class

String day []; // Number of days Array

}

 

Public int getYear (){

Return year;

}

 

Public void setMonth (int month ){

This. month = month;

}

 

Public int getMonth (){

Return month;

}

 

Public String [] getCalendar () {// obtain the calendar

String a [] = new String [42]; // defines an array of strings.
