Question

Write a Java program to simulate a pick 3, 4 or 5 lottery drawing. A lottery game of this type will draw values between 0 and 9. You should use the Math.Random() or the java.util.Random() class to generate the values in the lottery drawing. The program should prompt the user for which lottery game they want to play. The program should also ask how many times they want to play the game. The output should show the numbers picked for each game and the sum of the numbers of all games. Here is a sample run:

Which lottery game do you want to play (Enter 3 for pick-3, 4 for pick-4 or 5 for pick-5? 3 How many games would you like to play? 10

Thank you! The numbers selected were:
349
247
331
032
931
924
452
110
017
863
The sum for all numbers picked was: 107

I have the code but I want to make the code end if the user enters a wrong integer for what game they would like to play and output that the game entedered is incorrect. I think it should be a break statement but i havent been able to figure it out.
Also please let me know if my comments are correct. :)
Thank you!

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

public class Lottery{

   public static void main(String[] args){
  
   //Declare variables
   int game;
   int rounds;
   int lottoNumber;
   int numGenerator;
   int sum = 0;
  
   //Welcome message
   System.out.println("Welcome to the Lottery Game!");
  
   //Scanner
   Scanner userInput = new Scanner(System.in);
  
   //Lottery game selection
   System.out.println("Which lottery game do you want to play (Enter 3 for pick-3, 4 for pick-4 or 5 for pick-5)? ");
   game = userInput.nextInt();
  
   //Games selection      
   System.out.println("How many games would you like to play? ");
   rounds = userInput.nextInt();
  
   //Output message
   System.out.println("Thank you! The numbers selected were: ");
  
   //For loop
   for(int i = 0; i < rounds; i++){
       lottoNumber = 0;
       //Nested for loop
       for(int g = 0; g < game; g++){
           //Random number generator with numbers 0-9 only
           numGenerator = (new Random()).nextInt(10);
           lottoNumber = (lottoNumber * 10) + numGenerator;
           //Output of random numbers
           System.out.print(numGenerator + " ");
           //Equation for finding the sum of random numbers
           sum += numGenerator;
       }//End of nested for loop
       System.out.println();
   }//End of for loop
   //Output of the sum of numbers
   System.out.println("The sum for all numbers picked was: " + sum);
   }//End main method
}//End Lottery class

Explanation / Answer

Use this in your code to display a comment and close the program when game code entered is wrong:

//Lottery game selection
    System.out.println("Which lottery game do you want to play (Enter 3 for pick-3, 4 for pick-4 or 5 for pick-5)? ");
    game = userInput.nextInt();
  
if (game=3 || game=4 || game=5){

//leave blank here since the game code matched
    }
else{

//system.exit code will close the program

    System.out.println("Invalid game code entered ");
System.exit(0);

}

//Games selection
