Chapter 5, Problem 2GZ

Program Plan Intro

Lottery game application

Program plan:

• Import necessary package.
• Create a class “Lottery”,
  • Define the method “main ()”,
    • Declare and initialize the necessary variables.
    • Generate the three random numbers.
    • Combine three random numbers into a single three digit number.
    • Get the first digit entered into the first dialog box.
    • Assign the integer value returned form the method “parseInt()”.
    • Get the second digit entered into the second dialog box.
    • Assign the integer value returned form the method “parseInt()”.
    • Get the third digit entered into the third dialog box.
    • Assign the integer value returned form the method “parseInt()”.
    • Check whether the first, second and third digit is equal to the first, second and third random number generated respectively,
      • If it is true, set the match count to “4”.
    • Otherwise, check whether the first digit is equal to the first random number generated,
      • If it is true, increment the match count by “1”.
      • Set the first random value to “99”.
    • Otherwise, check whether the first digit is equal to the second random number generated,
      • If it is true, increment the match count by “1”.
      • Set the first random value to “99”.
    • Otherwise, check whether the first digit is equal to the third random number generated,
      • If it is true, increment the match count by “1”.
      • Set the first random value to “99”.
    • Check whether the second digit is equal to the first random number generated,
      • If it is true, increment the match count by “1”.
      • Set the first random value to “99”.
    • Otherwise, check whether the second digit is equal to the second random number generated,
      • If it is true, increment the match count by “1”.
      • Set the first random value to “99”.
    • Otherwise, check whether the second digit is equal to the third random number generated,
      • If it is true, increment the match count by “1”.
      • Set the first random value to “99”.
    • Check whether the third digit is equal to the first random number generated,
      • If it is true, increment the match count by “1”.
      • Set the first random value to “99”.
    • Otherwise, check whether the third digit is equal to the second random number generated,
      • If it is true, increment the match count by “1”.
      • Set the first random value to “99”.
    • Otherwise, check whether the third digit is equal to the third random number generated,
      • If it is true, increment the match count by “1”.
      • Set the first random value to “99”.
    • Check whether the match count is “4”,
      • If it is true,set the highest winning.
    • Otherwise, check whether the match count is “3”,
      • Set the second best winning.
    • Otherwise, check whether the match count is “2”,
      • If it is true, set the third best winning.
    • Otherwise, check whether the match count is “1”,
      • If it is true, set the low winning.
    • Otherwise, set the winning to “0”.
    • Display the output message in dialog box.
