Custom icon not being displayed

[drewtrcy]

I am working on a final project for my Java class and I have searched and searched to see what I am doing wrong because I am not able to get my icon to show up in my dialog box. In order for me to finish, I need that to show. If anyone can let me know what I am doing wrong, I would be much obliged. We haven't really spent any time on this icon thing which is why I am not able to figure it out. The icon is suppose to show after the initial question of if they want to play or not so that they can guess if the next roll of the die is going to be higher or lower. after trying over a half a dozen different code, this is what I gave up on.



import javax.swing.*;

public class P_Final_Exam {
public static void main(String[] args){

//ask player if they want to play
int answer = JOptionPane.showConfirmDialog(null, "Do you want to play?");

if (answer == JOptionPane.NO_OPTION){
System.exit(1);
}
int dice = random();
diceRoll();
//JOptionPane.showMessageDialog(null, random());
}
public static void diceRoll(){
//dice roll

ImageIcon icon = new ImageIcon ("icons/" + dice + ".png");

Object[] options = {"Higher",
"Lower",
"Cancel"};

int n = JOptionPane.showOptionDialog(null,
"Will the next roll be higher?",
"Dice Game",
JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE,
icon,
options,
options[0]);
}

//ask player if their guess is higher or lower

//generate random number for die and icon
public static int random(){
int num;
num = (int)(Math.random()*6) + 1;

return num;
}

//calculate score

//display final score on exit

}

I have redone the code and now have this which still isn't showing the icon.


import javax.swing.*;

public class P_Final_Exam {
public static void main(String[] args){

//ask player if they want to play
int answer = JOptionPane.showConfirmDialog(null, "Do you want to play?");

if (answer == JOptionPane.NO_OPTION){
System.exit(1);
}
int dice = random();

//diceRoll();
//JOptionPane.showMessageDialog(null, random());

ImageIcon icon = new ImageIcon ("icons/" + dice + ".png");
Object[] options = {"Higher",
"Lower",
"Cancel"};

int n = JOptionPane.showOptionDialog(null,
"Will the next roll be higher?",
"Dice Game",
JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE,
icon,
options,
options[0]);
}
//public static void diceRoll(){
//dice roll and guess



//}

//generate random number for die and icon
public static int random(){
int num;
num = (int)(Math.random()*6) + 1;

return num;
}

//calculate score

//display final score on exit

}

Don't you get error when you run?
cuz i coppied your code and runed but
you actually haven't declared 'dice' in the diceRoll method.

so you better declare again because 'dice' variable is local variable in the main method.

or declare the 'dice' variable in class level not in the main method level

[drewtrcy]

that has nothing to do with what I am asking, I just would like to know what I am doing wrong for my icon not to show up and if you read my code again you will see that dice = random() in the main part and that I have // in front of things that I have yet to begin working on. I am taking this one step at a time and in order for me to know what is going on I need that icon to show up. I know that the dice variable is working just fine because I have tested that out.

[wookyoo]

ok i see.
well then your program should work

cuz i didn't change any your code and copied and runned it.
while it runs after i check 'Yes' for the first dialog, icon is showed up in the second dialog.

[drewtrcy]

which compiler are you using, I am using NetBeans and it isn't showing for me

are you sure you're looking in the right place for your images? Are you looking relative to the user directory?

[drewtrcy]

I have the icons folder in the same folder as the .java file, is that not were it goes for it to run

No, you're probably not looking where you think you're looking. To find out where Java is looking for the image, place this in your code:

System.out.println(System.getProperty("user.dir"));

If you also print out your icon's getWidth() method result, I'll bet it's -1.

I have no clue as to what you are talking about, we never got that far in the book. Our instructor only took us up to and including Chapter 6 which is single dimensional arrays. She only gave us that one line of code for the icon to use that I used.



that little code pretty much told me that I had the folder too far in so I just brought it out one and it works, ty for that help

I am using Netbeans as well.
And My directory for the icons is
in the project folder

for exampe... my project folder is 'IconProject' then the icons folder is 'icons' in the project folder

So you're not smart enough to simply try to place that line of code I supplied in your program and read what it puts out?
