//整理一下
怎样用java 程序写一个时钟程序面向对象思想写成：
下面是一个显示器类
public class Display {
private int value;//现在的值
private int limit;//上限值
Display( int limit) {
this.limit = limit;
}
public void increase() {
value;
if(value =https://www.04ip.com/post/= limit) {
value = https://www.04ip.com/post/0;
}
}
public int getValue() {
return value;
}
public static void main(String[] args) {
Display d = new Display(24);
for(;;) {
d.increase();
System.out.println(d.getValue());
}
}
}
下面创建一个时钟对象：
public class Clock {
private Display h = new Display(24);
private Display min = new Display(60);
private Display s = new Display(60);
public void start () {
for(;;) {
s.increase();
if(s.getValue() == 0){//如果分重置，小时 1
min.increase();
if(min.getValue() == 0){//如果分重置，小时 1
h.increase();
}
}
System.out.printf("d:d:d\n",h.getValue(), min.getValue(),s.getValue());//格式输出
}
}
public static void main(String[] args) {
Clock clock = new Clock();
clock.start();
}
