I don't think we need to convert into String. Also in above example it will give an error for soo() because its not pagereference method.


Simple example :

----------- page -----------
<apex:page controller="sumController" >
     <apex:form >
         value of a = <apex:inputText value="{!a}"/>
         value of b = <apex:inputText value="{!b}"/>
         <apex:commandButton value="add" action="{!doAdd}" />
         total = <apex:outputText value="{!c}"/>
     </apex:form>
</apex:page>

------------ controller----------
public class sumController {
    public Integer a { get; set; }
    public Integer b { get; set; }
    public Integer c {get;set;}
    public pageReference doAdd(){
        c = a + b;
        return null;
    }
}

Please mark solved if it answered your question.

Thanks

I agree that we don't need to have a string variable.

By default, when we create using development mode, Salesforce created varaibles of string type and I didn't change it.

It will not give an error for soo() method. Pagereference is not mandatory for methods.

Hi Ankur, 

Could you make us aware about the error that you are getting?

Thank you.
