利用Calendar类来获取当前的日期

import java.util.Calendar;  
import java.util.GregorianCalendar;  
  
public class calendarTest {  
    public static void main(String[] args) {  
        Calendar calendar=Calendar.getInstance();  
        System.out.println(  
                "现在是："+  
                calendar.get(GregorianCalendar.YEAR)+"年"+  
                (calendar.get(GregorianCalendar.MONTH)+1)+"月"+  
                calendar.get(GregorianCalendar.DAY_OF_MONTH)+"日"+  
                calendar.get(GregorianCalendar.HOUR)+"时"+  
                calendar.get(GregorianCalendar.MINUTE)+"分"+  
                calendar.get(GregorianCalendar.SECOND)+"秒"  
                );        
    }  
}
