Got some trouble with JComboBox

I have some code like this:

int i ;
for( i = 0 ; i < jComboBox1.getItemCount(); i++)
{
if(jComboBox1.getSelectedIndex() == i)
{
jComboBox2.addItem(jComboBox1.getSelectedItem());
}
}
int index = jComboBox1.getSelectedIndex();
jComboBox1.removeItemAt(index);

I have 2 comboBox , first have 3 items , second have nothing.
I want : when we choose any item of First ComboBox, it will auto add to Second ComboBox,and then, the item we choose in First Box will auto remove.
And i got some trouble:
.First is : when the item from First Box auto add to Second Box, it auto add 2 same item .
.Second is : when i try to remove the item that we choose, it will remove all item from the item we choose to the last item.

Can you guys help me? Or tell me what i'm wrong! Thanks!!

Better to use action listeners for this. Did you try something related?

Oh, i use ItemStateChange for this.
I 'll try Action Listener.
Thanks Mod!

Oh my god! thanks MOD, when i use ActionPerform, everything work good! Thanks!!!

You are welcome. :) Try to identify the best thing for each process. Actually there are lots possibilities to do the same thing.

If you have solve the problem, please mark it.

Hello guys out there, Im so glad to be part of this as I surely can see that it is interesting... ;)
I have a problem with JComboBox, it is like this:
this is just a lil part of tha whole program

int[] arrayAugustMonthDays = new int[31];

(int count = 0; count < arrayAugustMonthDays.length; count++)
{
arrayAugustMonthDays[count] = count + 1;
}
JComboBox cboDate = new JComboBox(arrayAugustMonthDays);

but now it is giving me an error that it cannot resolve symbol
symbol : method parseInt (int[])

Please guys help!

Somewhere in your code, use parseInt method which don't have a overloaded function with an int array. Only you can pass a string value. Can't say about more without looking at the code.

What i think is that you are adding to jcombobox string but it takes only int so convert it into string first.

It's better to show your code, at least part of it.

No Im suppost to be adding an int array not a String data type. From what I've noticed is that it only accepts String array bcoz I've tried it and it works but now it will not work that way it is suppost to if I use String array. I've tried the Integer.parseInt and it still does gimme arrors. Somebody please help, this JComboBox is trouble.

Send the full code here. I hope it's not too long.

Wow guys after a while I've managed to pull out a few strings, it's finally working...
Just a piece of my work:

Integer[] arrayAugustMonthDays = new Integer[31];
JComboBox cboDate;

for(int count = 0; count < arrayAugustMonthDays.length; count++)
{
//converts to integer and assigns these values to array elements:cool:
arrayAugustMonthDays[count] = new Integer(count + 1);
}
cboDate = new JComboBox(arrayAugustMonthDays);

Nice to see that. What's the purpose of the following code segment.

Code:

---

new Integer(count + 1);

---

I don't really know how to explain this but the purpose of this code "new Integer(count + 1);" is that it is actually enabling the array to accept the the calculated value as integer as you can see from the code 'count' which start from 0 plus 1 and keeps on increasing untill count < arrayAugustMonthDays.length.

Ok, simply use the following line of code and see what happen in your application.

Code:

---

arrayAugustMonthDays[count] = (count + 1);

---

When I use the bellow code I get an error; 'Incompatible types'
arrayAugustMonthDays[count] = (count + 1);
And this one is working just fine;
arrayAugustMonthDays[count] = new Integer(count + 1);:)

Yes, it should be. I hope better to read more about arrays. :)
