Thread: dispose(); not working

That's a lot closer. I used a D not a d in the name. What you have will work, but it doesn't follow the naming conventions.

i updated the name.

Are you saying you do not know how to call a method?

You code must be full of calls to methods.
For example these statements are calls to methods:

     dispose();
 
     setVisible(false);
 
    transferControlToClass2();

callDispose  dispose = new callDispose ();

That's a call to a class's constructor. But there is no class named: callDispose. That is the name of a method.

Am i on the right track here?

What happened when you compiled and executed the code?

Can you make a small, complete program that compiles, executes and shows the problem?

Add a call to setVisible(false);

The code creates two JFrames:

 new game();
 
 JFrame frame = new JFrame();

and closes the game frame. The JFrame referred to by the frame variable is not closed.

in my original code i have so this why i have done it like this in the program. how do i fix it?

I was told i have to use EXTEND JFrame

    public class game extends JFrame {

There should only be one JFrame created. Get rid of one of them.

this is my original code when i get rid of frame nothing appears when it is complied
D OF ??

WHICH DO I GET RID OF ??

This one:
JFrame frame = new JFrame();

and use the one that Game extends.

How many lines of code did you remove? You were only supposed to remove ONE line:
JFrame frame = new JFrame();

That required that all usages of the variable: frame be changed to use the JFrame provided by the Game class. Basically just remove "frame."

so remove this line of code ????

JFrame frame = new JFrame();

if i do this there is error for cannot find symbol
symbol: method add(JPanel,String)
location: class Object

Post the new version of the code.
I made the changes I've described and it works for me.

did u make changes in the code which is on post no37?[COLOR="Silver"]

--- Update ---

That code isn't any good for testing. It needs to be complete.

Did you miss post#40 about removing "frame."?

here is the mini program you told me to make it works

IN MY ORIGINAL PROGRAM IT DOES NOT WORK WHICH IS WHAT IM TRYING TO GET WORKING

it works

Good, now look at how the code in post#45 works and copy that technique to the other code.

If there error messages, copy the full text and paste it here.

when i click the button to open the new gui it opens more than 1

The simple answer is to change the code so that it only opens one.
How many are openned?
Are all the new GUIs the same or are they all different?
How many places does the code create a GUI? Why is more than one executed?

it opens

it opens 4 for the new gui, they are the same

Interesting? I've never seen that. Usually its 2 like the code posted earlier.
Where are the statements that create those 4 instances?
Is there a loop that creates the 4 new instances of the same class?

--- Update ---

How many times is the actionPerformed() method called? The code in it creates a new Game2 every time it is called.

Add a println() method to the actionPerformed() method to see how many times it is called.
