check box

i have check box group if check box is checked i have to uncheck the check box can any body tell how to uncheck the checked check box in group?

thanks in advance

Check out the JCheckBox API to see if you find any method to select/deselect the box.

i am using awt

Have you been through the API documentation to see whether there are any methods for setting the box as selected or not?

can you tell what is difference between swing and awt?

Swing is more powerful, with a richer set of components including tables and trees.

What part are you having trouble with: determining which box is the checked one, or performing the unchecking?

If the former, one approach is to not bother and just attempt to uncheck them all.

And, dovetailing with with some of the other posters here, if you don't know why you're using AWT over Swing then you should probably just use Swing. (There are situations where AWT is called for, but they are relatively rare and I would think you would be aware of it if you were in one.)

i am doing exam project in this first question will come from database i am creating check box from group. it will have 4 checkbox for options in awt if user select any one checkbox and click next button it will display second question i am displaying question from label i
when icheckedoption for first question it will also checked for second question
i am changing label value using
radioopt1.setLabel

i had given but its not working

i am creating check box

Checkboxes essentially denote multiple choices. As per your description, a Radio button would be an appropriate choice.

Coming back to your problem, "it doesn't work" does not help us help you. Have you ensured (by debugging perhaps) that the uncheck code is really getting triggered? Always share the details
If you had peeked through the CheckBoxGroup API, you would have noticed setSelectedCheckbox method. Read the API documentation to figure out how to deselect all checkboxes in that group.

actually i am adding checbox in checkbox group can any body tell how to get the name of selected check box?

Did you even look at the CheckboxGroup API?

i saw the api but i am not able to get

I checked. The API lists 5 (yes, only five) methods.
Even the method description is in simple English.
I fail to understand how we can be more helpful.

hai maneesh

i understood this 5 methods but my requirment is different

How come?
You want the name of the selected checkbox.
The CheckBoxGroup gives you the selected CheckBox.
Once you got the CheckBox you can get the text.

how to get the selected object

You mean the variable name.
What you need is reflection

Why do you want to do it that way? The method getSelectedCheckbox() already gives you the instance.

thanks maneesh i gor
