Java Question

I want to display a text field that shows the cost of a selected item or items how would I go about this?

In my code I have two text areas one with all the items and prices in and a blank text area. When I input a value into a text field it puts the selected item from the first text area into the second text area.

Any help would be appreciated.

Thanks

Selected item? or matched item?

Just cut those matched item,
- have a copy of the content
- Remove that matched item
- Show the new content.

store in a temp variable,
- A String variable

append it to the 2nd textArea.

If you can post the content of your first textArea,
Much better......

When I enter a item number into a text field it brings up the item in the second text area.

private void makeItem() {
games[numberOfItems] = new Item("Ball", 39.99f);
numberOfItems++;
}

This is how I created the items I now want to get the 39.99f price out and put it into a separate text field. Also when I add more items I want it to add that to the total.

Thanks

Content, not code.....

(the text which appeared from your 1st textArea.)

Deleted code

I guess the content of your textArea is like:

Quote:

---

Grand Theft Auto IV
39.99f

FIFA 2008
37.99f

Assassins Creed
39.99f

Formula One Chapionship Edition
25.00f

Pro Evolution Soccer 2008
24.99f

Euro 2008
39.99f

Football Manager 2008
19.99f

am i right?

I still dont get how to do a cost field my code already works like i want it to and was complete until i wanted to include a cost field. I just want to display the cost of the selected items in a cost field

I doubt now....

@ first post, you're saying like
"transfer the matched text(based on textfield) from textArea1 to textArea2"

And now, you're just gonna display it? how?
I really don't understand you're problem.....

What is that cost field? textArea? List? or textfield?

You should be specific bro....

Im asking you if i am right at post #6.
Or, post that content like what i've guess @ #6

Yes the content of text area 1 is like that just without the f sorry didnt see that. Then when i select it, it copies the item from text area 1(Games) and puts it into text area 2 (games selected) and thats the one that i need to get the cost out of. To display in a NEW Cost text field that shows the cost which i have already created.

How did you select it? By highlighting it? or how?

After choosing that value for textArea1, what component did you use to trigger the value transfer?

I entered the number of the game and selected the submit game button that transfers it from games to selected games.

0.Grand Theft Auto IV (39.99)
1.Euro 2008 (39.99)

Code:

---

games[numberOfGames] = new Game("Grand Theft Auto IV", 39.99f);
numberOfGames++;

Base on the code you've posted,

It would be nice if you add those values on an array
Example:
gamename[x]
cost[x]....

eg: gamename[x] = name_of_the_game;
cost[x] = name_of_the_game_COST;

When you input a number, it should represents the gamename and cost right?

Try to access that cost[x] array to get the value...
And append to the second textArea.
