### Chapter 5 Exercise 32, Introduction to Java Programming, Tenth Edition Y. Daniel LiangY.

**5.32 (Game: lottery) Revise Listing 3.8, Lottery.java, to generate a lottery of a two digit number. The two digits in the number are distinct. (Hint: Generate the first digit. Use a loop to continuously generate the second digit until it is different from the first digit.)

import java.util.Scanner;

public class ProgrammingEX5_32 {

public static void main(String[] args) {

// Prompt the user to enter a guess
Scanner input = new Scanner(System.in);
System.out.print("Enter your lottery pick (two digits): ");
int guess = input.nextInt();
int lotteryDigit1;
int lotteryDigit2;
int lottery;
do {
// Generate a lottery
lottery = (int) (Math.random() * 100);
// Get digits from lottery
lotteryDigit1 = lottery / 10;
lotteryDigit2 = lottery % 10;
} while (lotteryDigit1 == lotteryDigit2);

// Get digits from guess
int guessDigit1 = guess / 10;
int guessDigit2 = guess % 10;

System.out.println("The lottery number is " + lottery);

// Check the guess
if (guess == lottery)
System.out.println("Exact match: you win $10,000"); else if (guessDigit2 == lotteryDigit1 && guessDigit1 == lotteryDigit2) System.out.println("Match all digits: you win$3,000");
else if (guessDigit1 == lotteryDigit1 || guessDigit1 == lotteryDigit2
|| guessDigit2 == lotteryDigit1 || guessDigit2 == lotteryDigit2)
System.out.println("Match one digit: you win \$1,000");
else
System.out.println("Sorry, no match");
}
