Chapter 6, Problem 22PE

Program Plan Intro

Simulation of game

Program plan:

• Import required package.
• Define “main()” function in a class “Hall”,
  • Initialize the necessary variables.
  • Create object for Random class.
  • Create "for" loop to simulate the game 1000 times
  • Get the values from the user using next() method and assign to the variables.
  • Check whether the player's door and the door with the car are equal.
    • If the condition is true, Player picked the car.
    • Otherwise, get leftover door by adding the current player door with the car door to yield a number between 1 and 3 and subtract from 3.
    • Calculate player door switch by adding leftover door with the current player door.
    • Check whether the player's door switch and the door with the car is equal.
    • If the condition is true, increment the count for strategy 1 by “1”.
    • Check whether the player's door and the door with the car are equal.
    • If true, increment the count for strategy 2 by “1”.
  • Print the output.
