Question

You will create a new program that simulates the game of Lotto. How does this work? The user will input 6 numbers (integer): ranging from 1 to 59. The computer will randomly pick the winning numbers (6 of them and one "Bonus number). In order to win first prize, the user must match all of the 6 numbers. In order to win second prize, the user must match 5 of the 6 numbers AND the Bonus number. Numbers CANNO T be generated twice. For example, 6, 18, 18, 50, 52, 55 is not valid; as 18 middot appears twice. Winning numbers (via the computer) arc always presented in ascending order. This lab MUST use Arrays for storing the numbers. Include data validation and echo user input!!!!! Fifteen points (15) will be deducted if the Java Source code has been modified and recompiled. In addition to solving the programming challenge, remember to include the internal documentation.

Explanation / Answer

import java.util.Random;
import java.util.Scanner;

public class Lotto {

//Pick 6 numbers from 1 to 100
//If all of your numbers gets called out, you win

public static void wait (int n) {
long t0,t1;
t0=System.currentTimeMillis();

System.out.println("Numbers will now start to be drawn, if all of your numbers are called, you win.");

while (true) {

}

if (num1Cor == true && num2Cor == true && num3Cor == true && num4Cor == true && num5Cor == true && num6Cor == true) {

break;
}

wait(100);
}
}
}
