打印当前时间。学习使用Date类和Calendar类。

“`
package test1;
import java.util.*;
public class Date {

public static void main(String[] args) {    // TODO Auto-generated method stub //Date nowTime=new Date();// System.out.println(nowTime);    Calendar calendar=Calendar.getInstance();    int year=calendar.get(Calendar.YEAR);    int month =calendar.get(Calendar.MONTH)+1;    int day=calendar.get(Calendar.DAY_OF_MONTH);    int hour=calendar.get(Calendar.HOUR_OF_DAY);    int minute=calendar.get(Calendar.MINUTE);    int second=calendar.get(Calendar.SECOND);    System.out.println("现在的时间是：");    System.out.println(""+year+"年"+month+"月"+day+"日");    System.out.println(""+hour+"时"+minute+"分"+second+"秒");}
