I need help making JButtons disappear when a condition is met (and also adding buttons when a condition is met) [duplicate]

Nothing appears to be wrong with this from what I have seen
Code for Driver:
import javax.swing.JFrame;
import java.util.Scanner;
import java.util.Random;
public class rpsDriver{
public static void main(String[] args){
//jpanel stuff
JFrame frame = new JFrame("Rock Paper Scissors Game");
frame.setSize(1280,720);
frame.setLocation(250, 50);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setContentPane(new rpsPanel());
frame.setVisible(true);
}//end main
}//end class
The problem I have is that when I run the code and me or the computer gets to 3 wins the end screen that says you win/lose appears but the rock, paper, scissors button on the left is still there (and I would like for it to disappear). Also, I would like to add buttons below the thing that says you win/lose that will let you restart the game (making userScore, tieScore, and compScore = 0), and a button that ends the game (closes the panel and ends the run). I'd appreciate any help.

I have a feeling that this error is caused because I have not repainted somewhere.

So, a list of issues...
First
There are two JFrames - which one is actually been used for what? As far as I can tell, SpillerOne is never displayed, so there is no possible way for it to be able to react to key events. Equally, your ActionListener doesn't seem to be attached to anything which can actually generate actions.
This also raises a bunch of questions about the relationship between SpillerOne and Grafik. They seem to be sharing variable names, but there is no way for them to be sharing state, so even if the KeyListener worked, Grafik would never reflect the changes in SpillerOnes state
Second
You've implemented your custom painting the wrong way. It's highly discouraged to override paint, instead, you should be overriding paintComponent AND calling super.paintComponent to ensure that requirements of the paint chain are upheld
See Performing Custom Painting and Painting in AWT and Swing for more details
You also seem to be putting a lot of state logic into your Grafik class, this is going to become exponentially more difficult to maintain as the complexity increases. Instead, each distinct operation should be it's own class, focused on performing as few dedicated operations as possible
Thirdly
KeyListener is a poor choice for monitoring for key events. While there are "hacks" that attempt to "solve" the focus related issues with KeyListener, none of them can achieve a reliable result.
If you do any research into KeyListener related issues, you will quickly find that the Key bindings API is often sighted as the most reliable solution to the problem
Overall
You code makes no sense. Why are there two frames? What is the ActionListener for and how is it attached to something that generates actions? Why doesn't the Grafik act as the key/action listener?
I think you have some significant thinking and redesigning to do

Processing, replacing text

I currently got this code for a poster I'm trying to make for a study (Gonna put it all, as it might be relevant):

}

}
}
Poster:
So when you push the buttons below the smartphone, relevant text should appear. For now it works individually, I click introduction, but to see one of the others I have to click introduction again to make it dissapear first.
What I need to do is make the text replace the other when another button is clicked.
I tried putting the other texts to true in the if statements, but it only worked for some of them, the others got kind of blocked.
Another thought was doing something in void mouseClicked(), but I'm unsure what.
Help is highly appreciated, thank you =)

Right now, you're only setting one variable for each button. Instead, what you want to do is set all of the variables.
Here is one example:
if(mouseX > 385 && mouseX < 685 && mouseY > 700 && mouseY < 750){
if(introduction == true){
introduction = false;
}
else{
features = false
storyboardtext = false;
introduction = true;
}
}
By the way, you could shorten all of the above:
if(mouseX > 385 && mouseX < 685 && mouseY > 700 && mouseY < 750){
features = false
storyboardtext = false;
introduction = !introduction;
}
You might also consider using an enum instead of 3 separate boolean values.

I recommend using an integer to keep track of states, with more states boolean become harder to manage and it's easier to make mistakes.
Here's a basic example:
final int INTRODUCTION = 0;
final int STORYBOARD = 1;
final int FEATURES = 2;
int state = INTRODUCTION;
void draw(){
switch(state){
case INTRODUCTION:
drawIntroduction();
break;
case STORYBOARD:
drawStoryboard();
break;
case FEATURES:
drawFeatures();
break;
}
}
void drawIntroduction(){
background(0);
fill(255);
text("Introduction",15,15);
}
void drawStoryboard(){
background(255);
fill(0);
text("Storyboard",15,55);
}
void drawFeatures(){
background(192);
fill(64);
text("Features",15,95);
}
void keyReleased(){
state = (state + 1) % 3;//cycle through states to test
}
I recommend using separate functions for drawing each state to keep the code tidier. Press any key to cycle through states.
The above, roughly adapted to your code, would look a bit like this:

Note that I'm unable to test this code(so there may be syntax errors), but the concept explained should be clear.

Java Poker Game - Change diamonds and hearts to red

I am working on a poker game in Java.
I would like to know how to make the diamond and heart symbol red instead of white filled, since I cannot find it in the unicode list.
Any help is appreciated.
EDIT: I would like to know how to paint the symbols to red.
This is my code so far:
import java.awt.*;
import java.awt.event.*;
import java.util.*;
public class PokerHand extends Frame implements ActionListener {
Button b = new Button("Click for new hand");
boolean dealt[] = new boolean[52];
String[] playercard = new String[10];
String[] playersuit = new String[10];
Random r = new Random();
int drawn;
public static void main(String args[]) {
PokerHand ph = new PokerHand();
ph.doIt();
}
public void doIt() {
int ct;
for (ct = 0; ct <= 9; ++ct) { // first loop that you learned tonight
playercard[ct] = " ";
playersuit[ct] = " ";
} // ends for loop
b.addActionListener(this);
this.setLayout(new FlowLayout());
this.add(b);
this.setSize(500, 500);
this.setVisible(true);
}// ends doIt method
public void paint(Graphics g) {
g.setFont(new Font(null, 1, 30));
g.drawString("Me", 400, 100);
g.drawString(playercard[0], 30, 100);
g.drawString(playersuit[0], 60, 100);
g.drawString(playercard[1], 90, 100);
g.drawString(playersuit[1], 120, 100);
g.drawString(playercard[2], 150, 100);
g.drawString(playersuit[2], 180, 100);
g.drawString(playercard[3], 210, 100);
g.drawString(playersuit[3], 240, 100);
g.drawString(playercard[4], 270, 100);
g.drawString(playersuit[4], 300, 100);
g.drawString("You", 400, 200);
g.drawString(playercard[5], 30, 200);
g.drawString(playersuit[5], 60, 200);
g.drawString(playercard[6], 90, 200);
g.drawString(playersuit[6], 120, 200);
g.drawString(playercard[7], 150, 200);
g.drawString(playersuit[7], 180, 200);
g.drawString(playercard[8], 210, 200);
g.drawString(playersuit[8], 240, 200);
g.drawString(playercard[9], 270, 200);
g.drawString(playersuit[9], 300, 200);
}
public void actionPerformed(ActionEvent ae) {
int ct;
ct = 0;
int card;
int suit;
// we draw 10 cards here
while (ct < 10) { // a while loop in practice
drawn = r.nextInt(52);
if (dealt[drawn] != true) { // if in practice
card = drawn % 13 + 1;
suit = drawn / 13;
dealt[drawn] = true;
playercard[ct] = String.valueOf(card);
if (card == 1) {
playercard[ct] = "A";
}
if (card == 11) {
playercard[ct] = "J";
}
if (card == 12) {
playercard[ct] = "Q";
}
if (card == 13) {
playercard[ct] = "K";
}
if (suit == 0) {
playersuit[ct] = "\u2660";
}
if (suit == 1) {
playersuit[ct] = "\u2661"; //change to red heart
}
if (suit == 2) {
playersuit[ct] = "\u2662"; //change to red diamond
}
if (suit == 3) {
playersuit[ct] = "\u2663";
}
ct = ct + 1;
} // ends if
}// ends while
repaint();
for (int x = 0; x <= 51; ++x)
dealt[x] = false;
}// ends method
}// ends the class

If your Unicode font has the hearts, clubs, diamonds and spades symbols, then all you need to do to draw them in the color of your choice is the same as drawing any other character in the color of your choice: simply use setColor.
Now you should start from the "filled" version of spades, hearts, diamonds and clubs, they are:
- spade: \u2660
- heart: \u2665 (use 2665 instead of 2661)
- diamonds: \u2666 (use 2666 instead of 2662)
- clubs: \u2663b
Then you simply do:
g.setColor(Color.RED);
g.drawString("\u2665");
And then you change the color, say, back to black to draw text and back to red/black for suits (or red, black, blue and green if you want to use a "four-color deck").

This is (FINALLY) working for me! Ultimately the unicode doesn't change for the suits themselves, it's the \uFE0F that makes it "pop" and give it the color.
public enum Suit {
SPADES("\u2660\uFE0F"), HEARTS("\u2665\uFE0F"), DIAMONDS("\u2666\uFE0F"), CLUBS("\u2663\uFE0F");
private final String icon;
Suit(String icon) {
this.icon = icon;
}
public String getIcon() {
return icon;
}
}

Hangman Graphics

I'm having trouble getting the graphics to show up with my hangman program.
This is the code for my engine class:
public static void main(String[] args)
{
//hangman viewer stuff
//////////////////////////////////////////////////////////////
JFrame frame = new JFrame();
frame.setSize(200,375); //invoked the method setSize on the implicit parameter frame
frame.setTitle("Hangman");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
HangmanComponent g = new HangmanComponent();
frame.add(g);
frame.setVisible(true);
///////////////////////////////////////////////////////////////
String wordd = JOptionPane.showInputDialog("Type in a word.");
int length = wordd.length();
String blank = "_ ";
String word2 = new String("");
int guesscount = 10;
ArrayList<String>answers=new ArrayList<String>(); //creates reference to empty structure that will contain references
char blanks[]=new char[wordd.length()]; //creates an array with the same number of terms as the length of the word
for (int i=0; i<length; i++)//fills the array with blanks corresponding to the length of the word
{
blanks[i] = '_';
}
HangmanComponent y = new HangmanComponent();
while (true)
{
String letter = JOptionPane.showInputDialog("Guess a letter! You have "+guesscount+" guesses."+"\n"+answers+"\n"+Arrays.toString(blanks).replace(",", " ").replace("[","").replace("]","")); //Prints a space
char letterchar = letter.charAt(0); //converts string letter to char letterchar
int idx = 0;
boolean found = false;
answers.add(letter); //adds the string to the arraylist answers
while (idx >= 0 && idx < length) //idx is greater than or equal to 0 but less than the length of the word
{
//System.out.println("idx = " + idx);
idx = wordd.indexOf(letter, idx); //idx is the index of "letter" in "wordd" and finds all instances of the letter
//System.out.println("idx = " + idx + ", guesscount = " + guesscount);
if (idx != -1) //if idx is not -1 (the letter exists in the word)
{
found = true;
blanks[idx] = letterchar; //sets the term in the array equal to the letter
idx += 1; //idx=idx+1
}
else
{
guesscount=guesscount-1;
y.nextStage();
y.printStage();
frame.add(y);
frame.setVisible(true);
break;
}
}
if (found)
{
JOptionPane.showMessageDialog(null, Arrays.toString(blanks).replace(",", " ").replace("[","").replace("]","")+"\n"+"You found a letter!"+"\n"+answers);
}
else
{
JOptionPane.showMessageDialog(null, Arrays.toString(blanks).replace(",", " ").replace("[","").replace("]","")+"\n"+"That letter is not in the word! Guess again!"+"\n"+answers);
if (guesscount == 0)
{
JOptionPane.showMessageDialog(null, "Sorry, you're all out of guesses. The answer was '"+wordd+".' Thanks for playing!");
break;
}
}
char [] lettersArray = wordd.toCharArray(); //converts word to array of chars
if (Arrays.equals(blanks, lettersArray))//compares array of blanks to array of letters
{
JOptionPane.showMessageDialog(null, "You guessed the word! Thanks for playing!");
break;
}
}
}
and this is the code for my HangmanComponent class (with the graphics)
int stage=0;
public void nextStage()
{
stage++;
}
public void printStage()
{
System.out.println("Your stage number is:"+stage);
}
public void paintComponent(Graphics g)
{
Graphics2D g2 = (Graphics2D) g;
g2.setStroke(new BasicStroke(5,BasicStroke.CAP_BUTT, BasicStroke.JOIN_BEVEL));
g2.setColor(Color.BLACK);
g.drawLine(50, 30, 50, 10);
g.drawLine(50, 10, 130, 10);
g.drawLine(130, 10, 130, 300);
g.drawLine(20, 300, 150, 300);
if (stage==1)
{
//draws the head
g2.setStroke(new BasicStroke(3,BasicStroke.CAP_BUTT, BasicStroke.JOIN_BEVEL));
Ellipse2D.Double head = new Ellipse2D.Double(25, 30, 50, 50);
g2.draw(head);
}
else if (stage==2)
{
//draws the body
g.drawLine(50, 80, 50, 180);
}
else if (stage==3)
{
//draws the left arm
g.drawLine(10, 150, 50, 100);
}
else if (stage==4)
{
//draws the right arm
g.drawLine(50, 100, 90, 150);
}
else if (stage==5)
{
//draws the left leg
g.drawLine(30, 250, 50, 180);
}
else if (stage==6)
{
//draws the right leg
g.drawLine(50, 180, 70, 250);
}
else if (stage==7)
{
//draws the left eye
Ellipse2D.Double lefteye = new Ellipse2D.Double(40, 50, 1, 1);
g2.draw(lefteye);
g2.fill(lefteye);
}
else if (stage==8)
{
//draws the right eye
Ellipse2D.Double righteye = new Ellipse2D.Double(58, 50, 1, 1);
g2.draw(righteye);
g2.fill(righteye);
}
else if (stage==9)
{
//draws the mouth
Arc2D.Double mouth = new Arc2D.Double(40.00, 50.00, 20.00, 20.00, 180.00, 190.00, Arc2D.OPEN);
g2.draw(mouth);
}
}
Right now, the hangman program runs perfectly fine, but the graphic is only added the first time the user inputs a wrong letter. How do I get the graphics to be inputted for every time a wrong letter is inputted?
