Question

Write a program that emulates the popular lottery game "Powerball". First ask the user how many times he wants to play. Then ask the user for 5 numbers between 1 and 69, and one additional "Power Ball" between 1 and 26. Then simulate the drawing as many times as indicated initially by creating random numbers in the given ranges, and comparing them to the numbers the user put in. After each drawing, let the user know if he won, and how many numbers he has guessed correctly. Output each drawing's result in the console.

       int powerBall; //selected power ball number
       System.out.print("Enter 5 distinct numbers between 1 and 69 ");

       }
       System.out.print("Enter power ball number between 1 and 26 ");
       powerBall = scanner.nextInt();
       int randomNumbers[] = new int[5]; // randomly generated lottery numbers

           {
               distinct = true;
               t = 1 + (int)(Math.random() * ((69 - 1) + 1)); // random number b/w 1 and 69
               for(int k=0;k<j;k++) if(randomNumbers[k]==t) distinct = false;
           }
           randomNumbers[j] = t;
           System.out.print(t+" ");
       }
       System.out.println();
       randomPowerBall = 1 + (int)(Math.random() * ((26 - 1) + 1));
       System.out.println("PowerBall Number : "+randomPowerBall);
       int count = 0;
       for(int j=0;j<5;j++) // compare correctly guessed
           for(int k=0;k<5;k++)
           {
               if(numbers[j]==randomNumbers[k]) count++;
           }
       if(powerBall==randomPowerBall) count++;
       System.out.println("You guessed "+count+" balls correctly");
       if(count==6) System.out.println("You Won");
       else System.out.println("You Lost");
   }
   }
}
