例8.1类的简单例子

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;
    int minute;
    int sec;
}

例8.2引用多个对象成员

public class cjava {
    public static void main(String[] args) {
        Time t1 = 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);
        Time t2=new Time();
        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;
    int minute;
    int sec;
}
