定义一个时钟类Clock,用属性时、分、秒来表示时间, 在构造方法中对属性进行初始化,成员方法printTime 用于显示时钟对象的时间。定义主类TestClock,在主 类的main方法中创建多个时钟
public class Clock { int hours; int minutes; int seconds; public Clock(int hours, int minutes, int seconds) { super(); this.hours = hours; this.minutes = minutes; this.seconds = seconds; } void printTime(){ System.out.println(hours+":"+minutes+":"+seconds); } } package gh; public class text7 { public static void main(String[] args) { Clock myClock1=new Clock(8,3,32); Clock myClock2=new Clock(12,5,2); myClock1.printTime(); myClock2.printTime(); } }
