Instructions:
(1) Time
Define a class named Time for encapsulating a time. The class contains the following:
1. A data field of the long time that stores the elapsed time since midnight, Jan 1, 1970.
2. A no-arg constructor that constructs a Time for the current time.
3. A constructor with the specified hour, minute, and second to create a Time.
4. A constructor with the specified elapsed time since midnight, Jan 1, 1970.
5. The getHour() method that returns the current hour in the range 0-23.
6. The getMinute() method that returns the current minute in the range 0-59.
7. The getSecond() method that returns the current second in the range 0-59.
8. The getSeconds() method that returns the elapsed total seconds.
9. The toString() method that returns a string such as "1 hour 2 minutes 1 second" and "14 hours 21 minutes 1 second".
10. Implement the Comparable interface to compare this Time with another one based on their elapse seconds. The compareTo method returns the difference between this object’s elapse seconds and the another’s.
11. Implement the Cloneable interface to clone a Time object.
Write a test program that produces the following sample run:
Enter time1 (hour minute second): XXXXXXXXXX
19 hours 45 minutes 14 seconds
Elapsed seconds in time1: XXXXXXXXXX
Enter time2 (elapsed time): XXXXXXXXXX
16 hours 22 minutes 25 seconds
Elapsed seconds in time2: XXXXXXXXXX
time1.compareTo(time2)? XXXXXXXXXX
time3 is created as a clone of time1
time1.compareTo(time3)? 0
Enter time1 (hour minute second):1 2 3
1 hour 2 minutes 3 seconds
Elapsed seconds in time1: 3723
Enter time2 (elapsed time): 193032
5 hours 37 minutes 12 seconds
Elapsed seconds in time2: 193032
time1.compareTo(time2)? XXXXXXXXXX
time3 is created as a clone of time1
time1.compareTo(time3)? 0
(2) Animal
The Animal class is given in Listing 13.7. Modify this class by implementing the Comparable interface and Cloneable Interface. Add the weight property in the Animal class with getter and setter methods. The two animals are compared based on their weights.
Use the following main method to run your test program.
publicstaticvoidmain(String[]args) {
Animal[]list=newAnimal[5];
list[0] =newChicken();
list[0].setWeight(4.5);
list[1] =newTiger();
list[1].setWeight(46.6);
list[2] =newChicken();
list[2].setWeight(1.5);
list[3] = (Animal)(list[0].clone());
list[3].setWeight(7.5);
list[4] = (Animal)(list[1].clone());
java.util.Arrays.sort(list);
for(inti= 0;ilist.length;i++) {
System.out.println("weight: "+list[i].getWeight());
}
}
