Java学习的第四十六天

1.例8.1例类

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

例8.2引用多个对象成员

import java.util.Scanner;
public class Cjava {
public static void main(String[]args) {
    Time t1=new Time();Time t2=new Time();
    Scanner s=new Scanner(System.in);
    t1.hour=s.nextInt();
    t1.minute=s.nextInt();
    t1.sec=s.nextInt();
    System.out.println(t1.hour+":"+t1.minute+":"+t1.sec);
    t2.hour=s.nextInt();
    t2.minute=s.nextInt();
    t2.sec=s.nextInt();
    System.out.println(t2.hour+":"+t2.minute+":"+t2.sec);
}
}
class Time{
    int hour,minute,sec;
}

2.没问题

3.明天继续写例题
