    Default Guessing Game

    Hello, I am trying to create a program that plays a game that has four different coloured blocks (red, green, blue, and yellow). The computer hides three of these coloured blocks from the user and then the user will try to guess the colours and order of the blocks. After display the colour of the three hidden blocks, the computer will display how many are correct and how many colours are in the right position. Based on the following information, the user can make another guess and so on until the user has determined the correct order and colour of the blocks. We have to use the following code - checkColoursCorrect(), checkPositionsCorrect(), randomWholeNumber() and newGame() which will write the code to generate three unique numbers from 1 to 4 for the block numbers. Here is what I have so far:

     
    package guesscolorblocks;
    import javax.swing.JOptionPane;
    import java.lang.String;
     
    public class GuessColorBlocks {
     
        private static int colours = 0, positions = 0; 
        /**
         *
         */
        public static void main(String[] args) {
            // Declare variables 
            int userSelection;
     
            //Set a button text in the array
            Object[] options = new String[] {"Yes", "No"};
     
            //Display the menu to allow the user to click an option
            int menu = JOptionPane.showOptionDialog(null, "Welcome to the Guess the Blocks Game!"
                    + "\nReady to start?:", "Red, Green, Blue, or Yellow", 
            JOptionPane.YES_NO_OPTION, JOptionPane.PLAIN_MESSAGE, null, options, options[0]);
     
        if (menu == JOptionPane.YES_OPTION) {
                playGame();
            } else if (menu == JOptionPane.NO_OPTION) {
                System.exit(0);
            }
        }
        public static void playGame () {
     
        String firstGuess = "", secondGuess = "", thirdGuess = "";
        int red, blue, green, yellow;
     
        String inputfirstGuess = JOptionPane.showInputDialog("Enter your first guess: (Red, Green, Blue, Yellow):");
        String inputsecondGuess = JOptionPane.showInputDialog("Enter your second guess: (Red, Green, Blue, Yellow):");
        String inputthirdGuess = JOptionPane.showInputDialog("Enter your third guess: (Red, Green, Blue, Yellow):");        
     
        int computerSelection = (int) ((Math.random() * 4) + 1);
     
            if (firstGuess.equalsIgnoreCase("red")) {
                firstGuess = "red";
                }
            else if (firstGuess.equalsIgnoreCase("green")){
                firstGuess = "green";
            }
            else if (firstGuess.equalsIgnoreCase("blue")){
                firstGuess = "blue";
            }
            else if (firstGuess.equalsIgnoreCase("yellow")){
                firstGuess = "yellow";
            }
     
     
            if (secondGuess.equalsIgnoreCase("red")) {
                secondGuess = "red";
                }
            else if (secondGuess.equalsIgnoreCase("green")){
                secondGuess = "green";
            }
            else if (secondGuess.equalsIgnoreCase("blue")){
                secondGuess = "blue";
            }
            else if (secondGuess.equalsIgnoreCase("yellow")){
                secondGuess = "yellow";
            }
     
     
            if (thirdGuess.equalsIgnoreCase("red")) {
                thirdGuess = "red";
                }
            else if (thirdGuess.equalsIgnoreCase("green")){
                thirdGuess = "green";
            }
            else if (thirdGuess.equalsIgnoreCase("blue")){
                thirdGuess = "blue";
            }
            else if (thirdGuess.equalsIgnoreCase("yellow")){
                thirdGuess = "yellow";
            }
          }
       }

    You are asking us to code your "Mastermind" clone for you. What do you specifically need help with?

    Well, I am trying to incorporate with the Math.random() function that the computer will randomly select a colour and if the user selection ex. blue matches the computer's selection with blue then it will input the correct number of colours guessed and the correct position they are in. Then the program will keep playing until the user gets it correctly. I don't know if that makes sense but all I am saying is I want to add the Math.random() function into the program for all cases.

    Can you explain what problems you are having using the Math.random() method?
    If you don't understand my answer, don't ignore it, ask a question.
