In my visualforce page I have two command button. I want to store boolean value into database against those radio button. I have chosen the field type as 'checkbox'. Please help me.

My vf code is

<apex:form >
    <div align="center">

        <apex:selectRadio value="{!Country}" > 
           India <apex:selectOption itemValue="true"></apex:selectOption>&nbsp;&nbsp;
          China &nbsp;&nbsp;<apex:selectOption itemValue="false"></apex:selectOption>

            <apex:actionSupport event="onchange" 
                    action="{!checkSelectedValue}" 
                    reRender="none"/>
            </apex:selectRadio>

        <apex:commandButton value="Show country" action="{!showCountry}"/>
    </div>
</apex:form>

My Controller is: `

public class RadioButtonTestController

{
public Boolean Country{get; set;}
public void checkSelectedValue()
{

    system.debug('Selected value is: '+ Country);
}

public void showCountry()
{
    String caseId = ApexPages.currentPage().getParameters().get('CaseID');
    list<Storing_Location__c> str = [Select Country__c from Storing_Location__c where CaseNumID__c=: caseId];
    Storing_Location__c obj = new Storing_Location__c();
    if(str.size()>0)
    {
        obj.Id = str[0].Id;
    }

    obj.Country__c = Country;
    system.debug('Selected value is:***********************:::'+Country);

}

}

I got a solution myself

The controller should be:

enter image description here

Here the database field "Country__c" is checkbox type. So it takes only Boolean value. If User select "India" then field "Country__c" will be checked otherwise not.
