时间的构造和重载

public class Mytime {
    int hour;
    int minute;
    int second;
    
Mytime(int h,int m,int s){
     hour=h;
     minute=m;
     second=s;
 }
public void addSecond(int sec){
    this.second=second+sec;
    
}
public void addMinute(int min){
    this.minute=minute+min;
}
public void addHour(int hou){
    this.hour=hour+hou;
}
public void subSecond(int sec){
    this.second=second-sec;
}
public void subMinute(int min){
    this.minute=minute-min;
}
public void subHour(int hou) {
    this.hour=hour-hou;
}
    
 void display(){
    System.out.println(hour+" "+minute+" "+second);

}


}

public class Test{
    public static void main(String[] args) {
Mytime t=new Mytime(6, 5, 3);
    t.display();
    t.addMinute(5);
    t.display();
        
}
