[ActionScript] number guessing game 1000 to 9999

2010-02-09T03:55:25-08:00

I have to create a program that guesses a number from 1000 to 9999 using an ArrayList and possibly an Iterator. When the user choses a number say 5432, the computer tries to guess it. say the computer spits out 1234, the user then says there is 1 match, the 3, but doesnt state the position. How do I go about coding this, hints would be appreciated

import java.util.ArrayList;
import java.util.Random;

import javax.swing.JOptionPane;

public class Assignment2 {
	ArrayList<Integer> num;
	
	
	public Assignment2 ( ){
		// fill in code here
		// initialization
		num= new ArrayList<Integer>();
	}

	public int myGuessIs() {
		// fill in code here

	}
	
	public int totalNumGuesses() {
		// fill in code here
		// this should return the total number of guesses taken

	}
 
	public void updateMyGuess(int nmatches) {
		// fill in code here
		// update the guess based on the number of matches claimed by the user

	}
	
	// fill in code here (optional)
	// feel free to add more methods as needed
	
	
	
	// you shouldn't need to change the main function
	public static void main(String[] args) {

		Assignment2 gamer = new Assignment2( );
  
		JOptionPane.showMessageDialog(null, "Think of a number between 1000 and 9999.\n Click OK when you are ready...", "Let's play a game", JOptionPane.INFORMATION_MESSAGE);
		int numMatches = 0;
		int myguess = 0;
		
		do {
			myguess = gamer.myGuessIs();
			if (myguess == -1) {
				JOptionPane.showMessageDialog(null, "I don't think your number exists.\n I could be wrong though...", "Mistake", JOptionPane.INFORMATION_MESSAGE);
				System.exit(0);
			}
			String userInput = JOptionPane.showInputDialog("I guess your number is " + myguess + ". How many digits did I guess correctly?");
			// quit if the user input nothing (such as pressed ESC)
			if (userInput == null)
				System.exit(0);
			// parse user input, pop up a warning message if the input is invalid
			try {
				numMatches = Integer.parseInt(userInput.trim());
			}
			catch(Exception exception) {
				JOptionPane.showMessageDialog(null, "Your input is invalid. Please enter a number between 0 and 4", "Warning", JOptionPane.WARNING_MESSAGE);
				numMatches = 0;
			}
			// the number of matches must be between 0 and 4
			if (numMatches < 0 || numMatches > 4) {
				JOptionPane.showMessageDialog(null, "Your input is invalid. Please enter a number between 0 and 4", "Warning", JOptionPane.WARNING_MESSAGE);
				numMatches = 0;
			}
			if (numMatches == 4)
				break;
			// update based on user input
			gamer.updateMyGuess(numMatches);
			
		} while (true);
		
		// the game ends when the user says all 4 digits are correct
		System.out.println("Aha, I got it, your number is " + myguess + ".");
		System.out.println("I did it in " + gamer.totalNumGuesses() + " turns.");
	}
