Write a Lottery
class that simulates a lottery. The
class should have an array of
seven integers named lotteryNumbers.
The constructor should use the Random class (from the Java API) to generate a
random number in the range 0 through 14 for each element in the array. The class should also have a method that
accepts an array of seven integers that represent a person's lottery
picks. The method is to compare the
corresponding elements in the two arrays and return the number of digits that
match. For example, the following shows
the lotteryNumbers array and the user's array with sample
numbers stored in each. There are three
matching digits (elements 3 and 5).
lotteryNumbers array

12 |
13 |
7 |
5 |
9 |
8 |
user's array
6 |

7 |
14 |
9 |
5 |
In addition, the
class should have a method that returns a copy of the lotteryNumbers array.
Your program
should ask the user to enter five numbers.
Your program
should display the number of digits that match the randomly generated lottery
numbers.
If all of the
digits match, display a message proclaiming the user a grand prize winner.
Your program
should have the usual javadocs information; echo the
input as usual; include inline comments; and have good indentation with no
lines that wraparound when printing
