java可视化日历程序,供大家参考,具体内容如下
利用DateFormat以及Calendar等方法来实现。
package 尚学堂;import java.text.DateFormat;import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Date;import java.util.GregorianCalendar;import javax.print.CancelablePrintJob;/** * 可视化日历程序 * @author lijiazhao * */public class TestCalendar2 { public static void main(String[] args) throws ParseException { // String str = "2020-9-10"; DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String str = df.format(new Date()); System.out.println("北京时间:"+df.format(new Date())+"\n"); Date date = df.parse(str); Calendar c = new GregorianCalendar(); c.setTime(date); int day = c.get(Calendar.DAY_OF_MONTH); int days = c.getActualMaximum(Calendar.DATE); System.out.println("日\t一\t二\t三\t四\t五\t六"); c.set(Calendar.DAY_OF_MONTH, 1); for(int i=0;i<c.get(Calendar.DAY_OF_WEEK)-1;i++) { System.out.print("\t"); } for(int i=1;i<=days;i++) { if(day == c.get(Calendar.DAY_OF_MONTH)) { System.out.print(c.get(Calendar.DAY_OF_MONTH)+"*\t"); }else { System.out.print(c.get(Calendar.DAY_OF_MONTH)+"\t"); } if(c.get(Calendar.DAY_OF_WEEK)==Calendar.SATURDAY) { System.out.println(); //换行 } c.add(Calendar.DAY_OF_MONTH, 1); } }}
