I am using NETBEANS and have several JLabels that need to display a specific icon/image based on a decision/boolean. I do not want to have to add a mouse listener for every JLabel and then copy and paste the code for each one. Rather I would prefer to use the x,y as the name of the JLabel and then set icon based on the x,y. I have no problems getting the x.y but cannot seem to figure out how to do something like this (xy.setIcon(new ImageIcon(Hit)); here is my code.
/**
* Mathematical coordinates of player1Fleet.
* Used to realign ships from Ship Class
* for use on game board.
*/
public void mouseClicked(MouseEvent e) {
Launch1();
}
public void FleetP1() {
for (Ship s : player1Fleet) {
int size = s.getSize();
for (int i = 0; i < size; i++) {
player1Ships.add((((s.getXCoordinate(i) + 1) * 45) + 90) + "" + (((s.getYCoordinate(i) + 1) * 45) + 180));
}
}
// Verification of Math
System.out.println(player1Ships);
}
/**
* Determine Hit or Miss based on location of Cross-hairs
* for player 1/West on game board.
* #return
*/
//public boolean setStrike1(){
public boolean Launch1() {
w93.setIcon(null);
player1Ships.clear();
FleetP1();
boolean strike1 = false;
boolean Launch = false;
for (int i = 0; i < this.player1Ships.size(); i++) {
if (this.player1Ships.get(i).equals(LblCrossHairs.getX() + "" + LblCrossHairs.getY())) {
strike1 = true;
//break;
}
if (strike1) {
strike1 = true;
(LblCrossHairs.getX() + "" + LblCrossHairs.getY()).setIcon(new ImageIcon(Hit));
//Launch = theAttack.Strike1(strike1);
//w93.setIcon(new ImageIcon(Hit));
URL url = this.getClass().getResource("MissleHit.au");
AudioClip ac = Applet.newAudioClip(url);
ac.play();
System.out.println("HIT");
break;
} else {
strike1 = false;
(LblCrossHairs.getX() + "" + LblCrossHairs.getY()).setIcon(new ImageIcon(Hit));
//w93.setIcon(new ImageIcon(Miss));
URL url = this.getClass().getResource("MissileMiss.au");
AudioClip ac = Applet.newAudioClip(url);
ac.play();
System.out.println("MISS");
}
}
TxtClick.setText(LblCrossHairs.getX() + "" + LblCrossHairs.getY() + ".setIcon");
return strike1;
}
Thank you in advance for all your help. This has been driving me crazy for the last two days
I do not want to have to add a mouse listener for every JLabel and then copy and paste the code for each one.
You don't have to create a separate listener. You can share the same listener with every JLabel. The basic code is:
public void mouseClicked(MouseEvent e)
{
JLabel label = (JLabel)e.getSource();
label.setIcon(...);
}

I'm currently setting up a quiz program right now, where the code will loop 20 times. There are 20 question, 80 answers (4 to each question) and the program will set JButtons and action listeners to listen for the user's answer for each question, then call the original quiz loop again from the correct or incorrect answer.
However, the program I'm having is that the program will display question 1, then question 2, but then question 4, 8, 16 and finally 20 since it cannot double anymore.
I've tried:
Breakpointing the value of the currentQuestion variable, as I believe this is the one which is doubling and causing the problem.
Creating a new method named updateQuestionAndAnswer to ensure that it's not a misclick.
Removing the other three action listeners, which helped me to find that it was whatever action listener that I clicked that was repeatedly being called. E.g if it was on Question 8 and I clicked listener 3, it would call listener 3 another 8 times.
I've enclosed the code below I think will be useful. All variables that you cannot see defined within here, are defined to 0 or "" in a static context outside of methods at the top of my program.

Thank you for your help,
I'm a beginner when it comes to Java and I'm trying to find a way to see if an object is located on certain coordinates. I've tried to search for similar questions, but I still haven't found an answer.
The program I'm working on is a map (image file) and the user should be able to create places and place them on the map (which will be displayed as triangles on the map). There is also this function where the user should be able to type in coordinates to see if there already is a place on those coordinates.
The object is an object of the class "Place" and consists a name, an x-coordinate and an y-coordinate.
Here is my code:
class CoordinatesListener implements ActionListener {
public void actionPerformed(ActionEvent ave) {
try {
CoordinatesForm c = new CoordinatesForm();
int answer = c.getAnswer();
if (answer != JOptionPane.OK_OPTION) {
return;
}
if (c.getPosition() == null) {
JOptionPane.showMessageDialog(null, "Invalid Input kkk", "Invalid Input", JOptionPane.ERROR_MESSAGE);
} else {
Position p = c.getPosition();
boolean flag = false;
for (Position key : positionList.keySet()) {
if (key.getXCoordinate() == p.getXCoordinate() && key.getYCoordinate() == p.getYCoordinate()) {
flag = true;
this.setAllMarkedPlacesUnMarked();
Place place = positionList.get(key);
if (place != null) {
System.out.println("the place " + place + "against position " + key);
place.setMarked(true);
if (!place.isVisible()) {
place.setVisible(true);
}
markedPlacesHashMap.put(place.getName(), place);
if (markedPlacesHashMap.containsKey(place.getName())) {
markedPlacesHashMap.get(place.getName()).add(place);
} else {
// ArrayList<Place> newMarkedPlaces = new ArrayList<>();
// newMarkedPlaces.add(place);
markedPlacesHashMap.put(place.getName(), place);
}
}
}
}
Also, when a place is created, the user shouldn't be able to place another place on the same coordinates. There should be an error message saying that a place already exists on those coordinates.
Here is the code where a place is created:
private void createNamedPlace(int x, int y, String answer) {
Position pos = new Position(x, y);
display.add(n = new NamedPlace(selectedCategory, pos, answer));
p = n;
places = new ArrayList<>();
placeByCategory = new ArrayList<>();
positionList.put(pos, n);
if (categoryMap.containsKey(selectedCategory)) {
categoryMap.get(selectedCategory).add(n);
if (nameList.containsKey(answer)) {
nameList.get(answer).add(n);
} else {
places.add(n);
nameList.put(answer, places);
}
} else {
placeByCategory.add(n);
categoryMap.put(selectedCategory, placeByCategory);
if (nameList.containsKey(answer)) {
nameList.get(answer).add(n);
System.out.println("The new Place have been added in the Name
List, the place name is :" + answer);
this.displayMap(nameList, " PlACES LIST BY NAME");
} else {
places.add(n);
nameList.put(answer, places);
this.displayMap(nameList, "PLACES LIST BY NAME");
}
this.displayMap(categoryMap, " PlACES LIST BY CATEGORY");
}
n.addMouseListener(new TriangleListener());
display.validate();
display.repaint();
display.removeMouseListener(mouseListener);
display.setCursor(Cursor.getDefaultCursor());
newButton.setEnabled(true);
categoryList.clearSelection();
isSaved = false;
}
All Swing components are ultimately derived from the Component class, which has a method getBounds(), returning a rectangle. So you can simply write something like
if (myComponent.getBounds().contains(x,y)) {
// do something
where x and y are the co-ordinates of the point you're trying to check.
I am building a Java Swing Memory Game. The idea is to click on the first card, it changes the image from a baseImage to another image. When the second card is clicked, it is supposed to do the same thing, wait for a few seconds, then reset everything back to base if they don't match or keep them flipped over if they do.
Right now, if they do not match, the second card never changes the image. Below is the relevant code. It should be noted that if they do match, the image shows and all is right and good in the world.
public void cardClickHandler(ActionEvent ae) {
JButton card = new JButton();
card = (JButton) ae.getSource();
// disable the card that was clicked
card.setEnabled(false);
// behavior for first card clicked
if (clickCounter == 0) {
firstCardClicked = card;
img = new ImageIcon("images2/img" + firstCardClicked.getName() + ".jpg");
firstCardClicked.setDisabledIcon(img);
System.out.println("Button " + firstCardClicked.getName() + " clicked!");
clickCounter++;
}
// behavior for second card clicked
else {
secondCardClicked = card;
img = new ImageIcon("images2/img" + secondCardClicked.getName() + ".jpg");
secondCardClicked.setDisabledIcon(img);
System.out.println("Button " + secondCardClicked.getName() + " clicked!");
clickCounter--;
}
// behavior if two cards have been clicked and they match
if (firstCardClicked.getName().equals(secondCardClicked.getName()) && clickCounter == 0) {
// player turn control and scoring
if (p1Turn) {
p1NumScore++;
p1Score.setText(Integer.toString(p1NumScore));
scorePanel.revalidate();
System.out.println("Good job Mike, got a pair!");
p1Turn = !p1Turn;
}
else {
p2NumScore++;
p2Score.setText(Integer.toString(p2NumScore));
scorePanel.revalidate();
System.out.println("Good job Peanut, got a pair!");
p1Turn = !p1Turn;
}
}
// behavior if two cards have been clicked and they do not match
else if (!(firstCardClicked.getName().equals(secondCardClicked.getName())) && clickCounter == 0) {
// keep cards flipped for a few seconds
try {
System.out.println("Before Sleep"); // testing
Thread.sleep(2000);
System.out.println("After Sleep"); // testing
}
catch (Exception e) {
e.printStackTrace();
}
// enable the cards and reset images
firstCardClicked.setEnabled(true);
firstCardClicked.setIcon(baseImage);
secondCardClicked.setEnabled(true);
secondCardClicked.setIcon(baseImage);
// change turns
p1Turn = !p1Turn;
System.out.println("Keep Playing");
}
}
It looks as though there were a few problems working at the same time. Thread.sleep() was causing havoc in conjunction with the .setEnabled(true) commands. The state of the objects were in question so I needed to clear them at the end of the code. There are some known issues with .setDisabledIcon() method that many posts here say require a .setIcon() to preceed it. Here is the fixed code that works with the javax.swing.Timer being used.
public void cardClickHandler(ActionEvent ae)
{
// method variables
JButton card = (JButton) ae.getSource();
boolean clearState = false;
// behavior for first card clicked
if (isFirstCard)
{
firstCardClicked = card;
// a known issue with "setDisabledIcon()" required the "setIcon()" method
firstCardClicked.setIcon(new ImageIcon("images2/img" + firstCardClicked.getName() + ".jpg"));
firstCardClicked.setDisabledIcon(new ImageIcon("images2/img" + firstCardClicked.getName() + ".jpg"));
// disable the flipped card
firstCardClicked.setEnabled(false);
// indicate the next card clicked is the second card
isFirstCard = false;
}
// behavior for second card clicked
else
{
secondCardClicked = card;
// a known issue with "setDisabledIcon()" required the "setIcon()" method
secondCardClicked.setIcon(new ImageIcon("images2/img" + secondCardClicked.getName() + ".jpg"));
secondCardClicked.setDisabledIcon(new ImageIcon("images2/img" + secondCardClicked.getName() + ".jpg"));
// disable the flipped card
secondCardClicked.setEnabled(false);
// indicate the next card clicked is the first card again
isFirstCard = true;
// indicate to the system both cards have been clicked and can clear objects
clearState = true;
}
// behavior if two cards have been clicked and they match
if (isFirstCard && firstCardClicked.getName().equals(secondCardClicked.getName()))
{
// player turn control and scoring
if (p1Turn)
{
p1NumScore++;
p1Score.setText(Integer.toString(p1NumScore));
scorePanel.revalidate();
p1Turn = !p1Turn;
}
else
{
p2NumScore++;
p2Score.setText(Integer.toString(p2NumScore));
scorePanel.revalidate();
p1Turn = !p1Turn;
}
}
// behavior if two cards have been clicked and they do not match
else if (isFirstCard && !(firstCardClicked.getName().equals(secondCardClicked.getName())) )
{
// enable the cards and reset images
firstCardClicked.setIcon(BASE_IMAGE);
secondCardClicked.setIcon(BASE_IMAGE);
// change turns
p1Turn = !p1Turn;
}
if (clearState)
{
javax.swing.Timer timer = new javax.swing.Timer(1000, new ActionListener() {
public void actionPerformed(ActionEvent ae) {

There are some problems with above constructions.
You do recursive move() method inside draw() method. But in Processing draw() is called many times in each second by animation thread.
Common desing for such cases is:
you should have variables that hold application state (logical state)
what your draw() method draws depends only on state
state may be modified by animation thread or by any other thread
I suggest changing your code a little:
First - state variables:
// 1 - display status, wait to enter values
// 2 - check if x and y are correct
// 3 - solve problem
int state=1;
boolean solutionExists=false;
public void setup() {
...
}
next draw() method:
void draw() {
counter=counter+1;
background(0,128,128);
String coords = "(" + x + "," + y + ")";
if (state == 1) {
if(solutionExists) {
textarea1.setText("Congratulations solution is possible " + coords);
} else {
textarea1.setText("Solution is not possible,enter other coordinates " +coords);
}
return;
}
if (state == 2) {
readXY();
return;
}
if (state == 3) {
println("find solution for: " + coords);
solutionExists = move(x,y,0);
state = 1;
return;
}
}
public void readXY() {
try {
x = Integer.parseInt(textfield1.getText().trim());
y = Integer.parseInt(textfield2.getText().trim());
state = 3;
} catch(Exception e) {
state = 1;
}
}
and finally textfields handlers:
public void tf1(GTextField source, GEvent event) {
if (event.getType().equals("LOST_FOCUS")) {
state=2;
}
}
public void tf2(GTextField source, GEvent event) {
if (event.getType().equals("LOST_FOCUS")) {
state=2;
}
}
As you can see:
if state==1 - draw() only updates message
if state==2 - draw() checks if x and y are valid, if valid -> change state to 3
if state==3 - draw() performs recursive algo, update solutionExists variable, change state to 1
Anytime when your textfield1 or textfield2 loose focus, it changes state to 2.
draw() is driven only by application state.
application state is modified by other events.
For best results, recursive algo should be performat in another thread, not in animation thread.
One fine note: when you edit textfield it may contains string such as "" (empty) or " 3" (leading space) or " 3 " etc - such text cannot be parsed with Integer.parseInt - you need to trim such text and be sure that NumberFormatException is not thrown - see readXY() method.
I am trying to have a mouse go through rooms to a target room. I am using a graph-like system with an x and y axis. I have a problem where the computer doesn't seem to want to add or subtract from an already existing variable.
Console:
The mouse is in room (5,4)
The mouse is in room (5,6)
The mouse is in room (6,5)
The mouse is in room (5,4)
The mouse is in room (5,6)
The mouse is in room (5,6)
Code for mouse:
package mouse_maze;
public class Mouse {
private int xCord = 5;
private int yCord = 5;
//position of the mouse when it starts
public int getXCord() {
return this.xCord;
}
public int getYCord() {
return this.yCord;
}
public void move() {
//method for the movement of the mouse
boolean verticalMove = Math.random() < .5;
boolean horizontalMove;
if (verticalMove == true)
horizontalMove = false;
else
horizontalMove = true;
int moveBy = 1;
if (Math.random() < .5)
moveBy = -1;
if (verticalMove) {
int test = this.yCord + moveBy;
if(test < 1 || test > 9) return;
this.yCord += moveBy;
}
if (horizontalMove) {
int test = this.xCord + moveBy;
if(test < 1 || test > 9) return;
this.xCord += moveBy;
}
System.out.println("The mouse is in room (" + xCord + "," + yCord + ")");
}
}
Code for maze:
package mouse_maze;
public class Maze {
private boolean onGoing = false;
private int tarX;
private int tarY;
//creates the target for the mouse.
public static void main(String[] args) {
new Maze(6, 8).init();
}
public Maze(int tarX, int tarY) {
this.tarX = tarX;
this.tarY = tarY;
}
public void init() {
this.onGoing = true;
while(this.onGoing)
this.iterate();
}
public void iterate() {
Mouse m = new Mouse();
m.move();
if (m.getXCord() == tarX && m.getYCord() == tarY) {
this.onGoing = false;
System.out.println("The mouse has beat the maze!");
//checks if the mouse has gotten to the target room.
}
}
}
First, learn to use a debugger, or at least learn to debug by whatever means. It is meaningless to always "assume" the problem without actually proving it.
Your whole problem has nothing to do with random etc.
In your iterate() method, you are creating a new mouse every time, instead of having the same mouse keep on moving.
