The program defines the class Clock,
|
| 2 |
+
which has the following operations that are useful for the solution:
|
| 3 |
+
method hours() which RETURNS the clock's hours as an integer
|
| 4 |
+
method minutes() which RETURNS the clock's minutes as an integer
|
| 5 |
+
method setTime(String time), which a time can be set in the format "hh.mm", example "15.45"
|
| 6 |
+
|
| 7 |
+
|
| 8 |
+
|
| 9 |
+
The program also defines 3 Clock-type variables:
|
| 10 |
+
realTime, which according to its name is set to the correct time
|
| 11 |
+
clock1 and clock2, which are in the wrong time
|
| 12 |
+
|
| 13 |
+
|
| 14 |
+
Your task is to set clocks 1 and 2 to the correct time using the methods described above.
