im fairly new to java and as my first assignment i need to simulate a MontyHall game using two classes. Door and MontyHall.
My main issue is with the class MontyHall. im having trouble simulating the selection of a random door and proceeding after that. Any help or hints to put me in the right direction would be much help.
import java.util.Random;
public class MontyHall {
// ADD YOUR INSTANCE VARIABLES HERE
private int door1; //door that holds the prize
private int door2; //one of the remaining two doors that doesnt have a prize
private int door3; //the last remaining door that doesnt have a prize
private int door4; //a door that the user chooses
Random generator = new Random();
/**
* Initializes the three doors.
*/
public MontyHall(){
// REPLACE THE BODY OF THIS METHOD WITH YOUR OWN IMPLEMENTATION
Door door1 = new Door("prizeDoor");
Door door2 = new Door("hostDoor");
Door door3 = new Door("finalDoor");
Door door4 = new Door("selectedDoor");
}
/**
* Simulates one Monty Hall game.
* <ol>
* <li>Resets all three doors</li>
* <li>Simulates the selection of one of the doors by the player</li>
* <li>Simulates opening of an empty door by the host</li>
* <li>prints the outcome for switching and not switching door to standard output</li>
* </ol>
*/
public void oneGame(){
// REPLACE THE BODY OF THIS METHOD WITH YOUR OWN IMPLEMENTATION
int door1 = generator.nextInt(3)+1; //assign a value for door1
System.out.println("The prize was behind door " + door1);
while(door2 == door1){
int door2 = generator.nextInt(3)+1; //assign a value for door2
}
while(door3 == door1 || door3 == door2){
int door3 = generator.nextInt(3)+1; //assign a value for door3
}
if (((door4 == door1) && (Door.SelectedByPlayer() == true)) || ((door4 == door2) && (Door.SelectedByPlayer() == true))){
System.out.println("Switching strategy would have lost");
} else{
System.out.println("Switching strategy would have won");
}
}
/**
* Simulates a random selection of one of the three doors.
* @return the door randomly selected
*/
private int pickADoor(){
// REPLACE THE BODY OF THIS METHOD WITH YOUR OWN IMPLEMENTATION
int door4 = generator.nextInt(3)+1;
return this.door4;
System.out.println("The player selected door " + door4);
}
/**
* Simulates the opening of one of the other doors once the player selected one.
* It should open a door chosen randomly among the ones that don't have the prize and
* that are not selected by the player
*
* @param prizeDoor the door that hides the prize
* @param selectedDoor the door that was selected by the player
* @return the door opened
*/
private int openOtherDoor(int prizeDoor, int selectedDoor){
// REPLACE THE BODY OF THIS METHOD WITH YOUR OWN IMPLEMENTATION
prizeDoor = door1;
selectedDoor = door4;
if(selectedDoor == prizeDoor){
int hostDoor = generator.nextInt(3)+1;
}
while(door2 != selectedDoor && door2 != prizeDoor){
int door2 = generator.nextInt(3)+1;
}
return this.door2;
System.out.println("The host opened door " + door2);
}
