Java学习的第四十七天

1.用类函数来写时间类

import java.util.Scanner;
public class Cjava {
public static void main(String[]args) {
Time t=new Time();
t.setTime();
t.showTime();
}
}
class Time{
    int hour,minute,sec;
    void setTime() {
        Scanner s=new Scanner(System.in);
    hour=s.nextInt();
    minute=s.nextInt();
    sec=s.nextInt();
    }
    void showTime() {
        System.out.println(hour+":"+minute+":"+sec);
    }
}

 2.没有问题

3.明天继续写
