Implementing JButton in this circumstance.
Hi all; I am new to Java, and definitely new to Swing. Basically, I am working on a University assignment that involves creating a game of Higher or Lower (the card game). Very simple I know. In the below code, I am taking input at the command line to choose the outcome of the conditionals. My question is, how can I do this using JButtons. So far, I have semi designed the UI in another class, the class also is holding the ActionListeners for the UI objects. I have also instantiated (think that the right term) an instance of each class in each others class so that they can "talk". Thanks in advance.
Java Code:import java.util.Scanner; public class CardGames { private ShowGui gui; private PackOfCards cardPack; //private CardDisplay display; private Scanner scan; private Card card; private Card cardTwo; private int winCounter; public CardGames(ShowGui guiInstance) { this.gui = guiInstance; cardPack = new PackOfCards(); scan = new Scanner(System.in); winCounter = 0; } public void higherOrLower() { //Shuffle the pack. cardPack.shuffleCards(2000); //Prompt the user. See chart for Logic structure. while (true) { System.out.println("*********************************************"); //Get the next card. cardTwo = cardPack.getNextCard(); //Print the name of the first card. card = cardPack.getNextCard(); System.out.println("The first card is:"); System.out.println(card.getName()); //display.displayCard(card); gui.displayCard(card); System.out.println("Higher or Lower?"); int userInt = scan.nextInt(); if (userInt == 0) { System.out.println("You selected Higher;"); if (card.getValue() < cardTwo.getValue()) { System.out.println("Well done, the card was "+cardTwo.getName()+""); winCounter++; } else { System.out.println("Sorry, that is not correct."); winCounter--; } } else if (userInt == 1) { System.out.println("You selected Lower;"); if(card.getValue() > cardTwo.getValue()) { System.out.println("Well done, the card was "+cardTwo.getName()+""); winCounter++; } else { System.out.println("Sorry, that is not correct."); winCounter--; } } else if (userInt == 2) { System.out.println("You have chosen to view your winnings."); if (winCounter <= 0) { System.out.println("Sorry, your score is "+winCounter+". This does not qualify for a prize."); } else if (winCounter >=1 && winCounter <=3) { System.out.println("You have won a Tier 1 prize. Your score is "+winCounter+""); } else if (winCounter >=4 && winCounter <=7) { System.out.println("You have won a Tier 2 prize. Your score is "+winCounter+""); } else if (winCounter >=8) { System.out.println("You have won a Tier 3 prize. Your score is "+winCounter+""); } } else { System.out.println("Please enter a valid option."); } } } }

Shameless bump here.
I am not sure that I explained myself thoroughly the first time, basically, at the moment, the while loop takes input from a Scanner, the integer that is entered into the scanner is placed in an int variable. There are then various if's and else if's that decide on the behaviour. What I need to do is somehow meet these different conditions with my JButtons. I am aware at the moment that it is an infinite loop, but I do have a menu item that invokes System.exit(0);.
Thanks a lot.
Sorry for the bump.
