Java Perpetual calendar and java Perpetual calendar code

Recently, I have been working hard to supplement the professional courses that have been delayed due to ACM.

Unfortunately .. You can only do this step by step.

Mycalender:

Import java. awt. *; public class mycalender {public static void main (String [] args) {WindowActionEvent win = new WindowActionEvent (); ReadListen listener = new ReadListen (); // create a monitor (listener can be any) Container con = win. getContentPane (); con. setBackground (Color. green); win. setMycommandListener (listener); // window combination monitor win. setTitle ("-- My perpetual calendar ---"); win. setBounds (100,100,610,560 );}}

WindowActionEvent:

Import java. awt. *; import javax. swing. *; import java. awt. event. *; public class WindowActionEvent extends JFrame {JTextField textInput; JTextArea textShow; JButton button; public WindowActionEvent () {init (); setVisible (true); setdefaclocloseoperation (JFrame. EXIT_ON_CLOSE);} void init () {// construction window setLayout (new FlowLayout (); add (new JLabel ("Enter the year you want to query (after January 1, 1900 ): "); textInput = new JTextField (15); add (textInput); button = new JButton (" OK "); add (button ); add (new JLabel ("the calendar of this year is:"); textShow = new JTextArea (); add (new JScrollPane (textShow);} void setMycommandListener (ReadListen listener) {listener. setJTextField (textInput); listener. setJTextArea (textShow); button. addActionListener (listener); // button is the event source, and listener is the monitor textInput. addActionListener (listener); // textInput is the event source, and listener is the monitor }}

ReadListen:

Import java. awt. event. *; import javax. swing. *; public class ReadListen implements ActionListener {JTextArea textShow; JTextField textInput; public void Merge (JTextArea area) {textShow = area;} public void setJTextField (JTextField text) {textInput = text ;} public void actionreceivmed (ActionEvent e) {double nowyears = Double. parseDouble (textInput. getText (); print (nowyears);} void print (double nowyears) {int da Y = 0, mon [] = {1990, 28, 31, 30, 31, 30, 31, 30, 31}; for (int year =; year <nowyears; year + +) {if (year % 4 = 0 & year % 100! = 0 | year % 400 = 0) day + = 366; elseday + = 365;} int week = (day + 1) % 7; textShow. setText ("1st month: \ n day \ t one \ t Two \ t three \ t four \ t five \ t six \ n "); if (nowyears % 4 = 0 & amp; nowyears % 100! = 0 | nowyears % 400 = 0) mon [2] = 29; elsemon [2] = 28; int Monday = 1; while (Monday <13) {int t = 1; if (week = 7) week = 0; for (int I = 0; I <week; I ++) textShow. append ("\ t"); while (t <= mon [Monday]) {if (week = 7) {week = 0; textShow. append ("\ n");} textShow. append (t + "\ t"); t ++; week ++;} textShow. append ("\ n"); Monday ++; if (Monday = 13) break; textShow. append ("nth" + Monday + "month: \ n"); textShow. append ("day \ t one \ t Two \ t three \ t four \ t five \ t six \ n ");}}}

Here is the running result:
