Please help me with the java.

1.Define a derived class, AlarmClock, to represent an alarm clock, with the following Clock class as its base class.

public class Clock {

private int hour;

private int minute;

private int second;

//default constructor

public Clock() {

//initialize to default values

hour = 0;

minute = 0;

second = 0;

}

//constructor with arguments

public Clock(int h, int m, int s) //set current time

{

hour = h;

minute = m;

second = s;

}

}

a. In your AlarmClock subclass, you only need to consider the following two aspects:

The AlarmClock should have three instance variables: alarmHour, alarmMinute, and alarmSecond.

b. Please write two constructors of the derived class AlarmClock -- one is the default constructor that assigns all member/instance variables to zero. The other takes 6 arguments time (ie., hour, minute, second, alarmHour, alarmMinute, alarmMinute.) that sets current time and alarm

(no need to write any other methods)
