    copied!<p>Hi guys I wrote a program to simulate the drinking card game Kings. This is my third Java Project</p> <p><strong>During my <code>playGame()</code> on a players turn to choose, which is handled by <code>getChoice()</code> the GUI SOMETIMES (like 5% of the time) renders a JPanel with the correct title but otherwise blank!</strong> Why is this happening?</p> <p>Pic:</p> <p><img src="https://i.stack.imgur.com/3Xb2J.png" alt="JPANEL FREEZE/RENDER ISSUE"></p> <p>The explanation of the game is in the code comment box here:</p> <pre><code> /** * @author :KyleMHB * Project Number :0003 * Project Name :Kings * IDE :NETBEANS * Goal of Project - * Kings is a rule based drinking game using cards for 4+ players. * The Rules are read in from a rules.txt so that one can easily change the rules. * How the game works: * Players shuffle a deck of cards, place a glass between them and circle the * cards around the base of the glass. * The players then take turns picking cards, each card has its own rule associated to it. * Most importantly, there are 4 Kings, each time a King is picked, * the player who picked it can pour as much of his/her drink into the glass between * them as they wish. * The game ends when the fourth and final King is picked. * The player to pick the final King must down the glass in the center of table. */ package kings; import java.io.File; import java.io.FileNotFoundException; import java.io.IOException; import java.nio.charset.Charset; import java.nio.file.Files; import java.util.ArrayList; import java.util.Collections; import java.util.List; import java.util.Random; import javax.swing.JOptionPane; public class Kings { public static class Card { private int rank, suit; private String[] suits = { "Hearts", "Spades", "Diamonds", "Clubs" }; private String[] ranks = { "Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King" }; Card(int suit, int rank){ this.rank=rank; this.suit=suit; } public @Override String toString(){ return ranks[rank] + " of " + suits[suit]; } public int getRank() { return rank; } public int getSuit() { return suit; } } public static class Deck { private static ArrayList&lt;Card&gt; cards; Deck() { cards=new ArrayList&lt;Card&gt;(); for (int a=0; a&lt;=3; a++){ for (int b=0; b&lt;=12; b++){ cards.add( new Card(a,b) ); } } Collections.shuffle(cards, new Random()); Collections.shuffle(cards, new Random(System.nanoTime())); } public Card drawFromDeck(){ return cards.remove( 0 ); } public int getTotalCards(){ return cards.size(); } } private static List&lt;String&gt; rules; public static void main(String[] args) throws FileNotFoundException, IOException { setRules(new File("rules.txt")); playGame(getNum("How many people are going to play","Number of Players")); } /** * Rules are not hard-coded because people often have different ones, * Therefore I made an easily editable rules.txt file. * Also my rule file has formatting in using the \n, * However when the file is read it is read as \ and n * Hence why I used the replaceAll( "\\\\n","\n"); */ private static void setRules(File f) throws FileNotFoundException, IOException { rules = Files.readAllLines(f.toPath(), Charset.defaultCharset()); for(int i=0; i!=rules.size(); i++){ rules.set(i, rules.get(i).replaceAll( "\\\\n","\n")); } } private static int getNum(String prompt,String title) { return Integer.parseInt(JOptionPane.showInputDialog(null,prompt,title,3)); } private static void playGame(int players) { int playerTurn; int choice; int kings=0; Card cardDrawn; Deck deck=new Deck(); while(true){ playerTurn=0; while (playerTurn!=players){ choice=getChoice("Player "+(playerTurn+1), "Would you like to skip or draw?", "Draw","Skip","Exit"); if (choice==0){ cardDrawn=deck.drawFromDeck(); System.out.println(cardDrawn); kings+=showCard(cardDrawn,kings,playerTurn+1); playerTurn++; } else if(choice==1) playerTurn++; else System.exit(0); }//Turn reset loop }//continuous loop } private static int getChoice(String title, String prompt, String a, String b, String c) { Object[] options = { a, b, c}; return JOptionPane.showOptionDialog(null, prompt, title,0,2, null,options,options[0]); } private static int showCard(Card a, int kings, int player) { if(a.rank==12) if(kings==3){ JOptionPane.showMessageDialog(null, "Player "+player+" has Drawn the Final King\n\n" + "Restart the Program to Play again",a.toString(),1); System.exit(0); return 0; } else{ JOptionPane.showMessageDialog(null,"Player "+player+ " has drawn the "+a.toString()+"\n" + "Which is King "+(kings+1)+"/4\n\n" +rules.get(a.rank),a.toString(),1); return 1; } else{ JOptionPane.showMessageDialog(null,"Player "+player+ " has drawn the "+a.toString()+"\n\n" + rules.get(a.rank),a.toString(),1); return 0; } } } </code></pre>
