打印当前时间。学习使用Date类和Calendar类。（教材P194页）

代码

package javawork;
import java.util.Calendar;
public class Time {
public static void main(String[] args) {
Calendar calender=Calendar.getInstance();
int year=calender.get(Calendar.YEAR);
int month=calender.get(Calendar.MONTH);
int date=calender.get(Calendar.DATE);
int hour=calender.get(Calendar.HOUR_OF_DAY);
int minute=calender.get(Calendar.MINUTE);
int second=calender.get(Calendar.SECOND);
int week=calender.get(Calendar.DAY_OF_WEEK);
System.out.println(year + "/" + month + "/" + date + " " +hour + ":" +minute + ":" + second + "星期："+(week-1));

}
}

运行结果
