Multiple issues with my 1-6 guessing game.

[intEquals_EJ]

Hi all,

First I want to thank all of you for your help. Secondly, I stink at object-oriented programming. I think it has something to do with how I logically think. Lastly, I read through as much forums and did as much google(ing) as I possibly could.

The program is a guessing game that is from 1 -6. I have the opening message working. The userChoice method works also, but I am trying to add a counter because I know the actual value of "1" is 0.

 public static void userChoice() //This method allows the user to click a number in the following showOptionDialog
        {
         int getChoice;// this stores the users choice into an integer variable
            
     
             int mouseClick = JOptionPane.QUESTION_MESSAGE; // this stores the click into a variable

        String[] options = { "1", "2", "3", "4", "5", "6", "Exit"}; // END STRING OPTIONS

        getChoice = JOptionPane.showOptionDialog (null, "Choose a Figure", "Title", 0, mouseClick, null, options, options[2]);

		    if (getChoice >= 0)
			 
              System.out.println ("You clicked " + options[getChoice]);
           // END IF
          else
			 {
              System.out.println ("You closed the box.");
          } // END ELSE
   
                    randomNum(); //this moves the program to the next method
        } // END METHOD USERCHOICE

I think that it goes somewhere after the if statement or that I may have to change it to a do while loop.


Another issue I am having is comparing the data gathered from the userChoice method to the randomNum / getRand methods.

public static void randomNum() //random number generator method 
        {                                      // put in its own method when done
           int counter = 1;
           int getNum;

           do
           {
           	 getNum = getRand();
           	 counter++;                           // same as ctr  = ctr + 1;
           } while (counter <= 6); 
           
           System.out.println ("The roll was " + getNum);
           // use do while loop for fun

        }// main

        public static int getRand()  // returns an int value via the return statement
        {
        	Random generator = new Random();  // declare a new Instance of type Random

           int  rNum  = generator.nextInt(6) + 1; //  generator.nextInt(6) creates numbers from 0 to 5;  thus the reason to add 1

           return rNum;  // return value

My apologies if you cannot understand what I am trying to get accomplished. I am very well spoken but not in Java programming.

Have you considered passing the getChoice variable to the randomNum method? Then, you can just say

if( getChoice == getNum) System.out.println("match found"); 
else System.out.println("match not found");

This could be placed in the randomNum() method.

[intEquals_EJ]

int x = 5;
doStuff(x); // pass a COPY of x (the value 5) to the doStuff method

The doStuff method looks like this:

void doStuff(int y) {

   // use y in some way
}

A copy of the value in x, which is 5, is passed into the doStuff() method.

I am trying to do this except "x" equals "getChoice" and there is no equal sign. No value assigned to getChoice. I want to pass a copy of getChoice to the randomNum(); method like you said.


I have also tried assigning the getChoice variable to itself to no avail.
