Answer 1

import java.util.Calendar;

public class Time {

private int hour;

private int minute;

private int second;

Calendar c = Calendar.getInstance();

public Time(){
this.setPro();
}

public Time(long time){
c = Calendar.getInstance();
c.setTimeInMillis(time);
this.setPro();
}

public Time(int hour, int minute, int second){
c = Calendar.getInstance();
c.set(Calendar.HOUR, hour);
c.set(Calendar.MINUTE, minute);
c.set(Calendar.SECOND, second);
this.setPro();
}

public void setTime(long time){
c = Calendar.getInstance();
c.setTimeInMillis(time);
this.setPro();
}

private void setPro(){
hour = c.get(Calendar.HOUR);
minute = c.get(Calendar.MINUTE);
second = c.get(Calendar.SECOND);
}

public static void main(String[] args) {
Time t1 = new Time();
Time t2 = new Time(555550000);

System.out.println(t1.getHour()+":"+t1.getMinute()+":"+t1.getSecond());
System.out.println(t2.getHour()+":"+t2.getMinute()+":"+t2.getSecond());
}

public int getHour() {
return hour;
}

public void setHour(int hour) {
this.hour = hour;
}

public int getMinute() {
return minute;
}

public void setMinute(int minute) {
this.minute = minute;
}

public int getSecond() {
return second;
}

public void setSecond(int second) {
this.second = second;
}

}
