Question

Create a program that generates SuperLotto lottery numbers.

Create a class called SuperLottoPlus.java

Create a static method called generateSuperLottoNumbers() that returns an array of 6 random SuperLotto lottery numbers.

Must have correct method signature, and return the entire array of lotto numbers. [1 pt]

The first 5 numbers must be from the range 1 to 47 [1 pt]

The 6th number (the MEGA) must be from 1 to 27. [1 pt]

Create a static method called printTicket() that takes an integer array as an parameter

Must have the correct method signatures [1 pt]

it will loop through the integer array and print out the data [1 pt]

Display the data in the format: 47 22 25 4 13 (MEGA: 14)

In the main method

Ask the user how many lotto tickets they want.

If the user enters 5, for example, then using a for loop, loop 5 times. [1 pt]

In each loop iteration, call the printTicket() method, passing a call to the method generateSuperLottoNumbers() as an agrument [1 pts]

Hint: numbers[i] = (int) (10 * Math.random()) + 1; // will assign your array element to a random number from 1 to 10. You can also create the random numbers by creating an object of the Random class.

Extra Credit: Create another method called generateSuperLottoNoDupes() which does the same thing as generateSuperLottoNumbers(), but returns an array without duplicates in the first 5 numbers. It is OK for the MEGA number to be a duplicate of any of the first 5 (+1 point)

Example output:


How many Super Lotto tickets do you want?
4
28 8 11 9 28 MEGA (4)
38 39 29 47 27 MEGA (27)
15 17 33 12 6 MEGA (19)
30 29 18 20 31 MEGA (12)

Explanation / Answer

import java.util.Scanner;

public class SuperLottoPlus

{

public static int[] generateSuperLottoNumbers()

{

int[] numbers;

numbers = new int[5];

numbers[0] = (int) (47 * Math.random()) + 1;

numbers[1] = (int) (47 * Math.random()) + 1;

numbers[2] = (int) (47 * Math.random()) + 1;

numbers[3] = (int) (47 * Math.random()) + 1;

numbers[4] = (int) (47 * Math.random()) + 1;

numbers[5] = (int) (27 * Math.random()) + 1;

return numbers;

}

public static void printTicket(int [] array)

{

int i;

for(i = 0; i < array.length ; i++)

{

System.out.println(array[i]);

}

}

public static void main (String[] args)

{

int n;

Scanner keyboard = new Scanner(System.in);

System.out.println("How many lottery tickets would you like?");

n = keyboard.nextInt();

for(int i = 0; i < n; i++)

{

printTicket(generateSuperLottoNumbers());

}

}

}
