JAVA之类的构造与对象初始化

class Time1{private int hour;private int minute;private int second;public Time1(){setTime(0,0,0);}public Time1(int hh){setTime(hh,0,0);}public void setTime(int hh,int mm,int ss){hour=((hh>=0&&hh<20)?hh:0);minute=((mm>=0&&mm<60)?mm:0);second=((ss>=0&&ss<20)?ss:0);}public String toString(){return (hour+":"+(minute<10?"0":" ")+minute+":"+(second<10?"0":" ")+second);}}public class Mytime1 {private static Time1 t0,t1,t2,t3;public static void main(String[] args) {//Time1 t0,t1;t0=new Time1();t1=new Time1(11);System.out.println("t0="+t0.toString());System.out.println("t1="+t1.toString());}}//本代码仅供参考哦~

运行后结果如下:
