可视化日历程序

这是一个在学习北京尚学堂高琪老师的课程后 用于自己学习记录的程序。

import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Date;import java.util.GregorianCalendar;import java.util.Scanner;/** * 可视化日历程序 * @author Dylan * */public class VisualCalendar {public static void main(String[] args) {System.out.println("请输入日期：（年-月-日）：");Scanner scanner = new Scanner(System.in);String inputstr = scanner.nextLine();SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");try {Date date = format.parse(inputstr);Calendar calendar = new GregorianCalendar();calendar.setTime(date);Date d = calendar.getTime();int day = calendar.get(Calendar.DATE);calendar.set(Calendar.DATE,1);System.out.println("日\t一\t二\t三\t四\t五\t六");for(int i=1;i<calendar.get(Calendar.DAY_OF_WEEK);i++){System.out.print( '\t');}for(int i=1;i<=calendar.getActualMaximum(Calendar.DAY_OF_MONTH);i++) {if(i==day){System.out.print('*');}System.out.print(i+"\t");int w = calendar.get(Calendar.DAY_OF_WEEK);if(w==7){System.out.println();}calendar.add(Calendar.DATE,1);}} catch (ParseException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}
