Visualforce : Dynamically displaying fields based on controller variable

Question

I have a custom object C.

It has two fields F1__c and F2__c.

In my controller there is a String s.

The s contains "F1__c"

Will it be possible for me to display this field whose API name is contained in the variable s ?

public xyzcontroller 
{

public String s{get;set;}

public xyzcontroller()
{

s = "F1__c";

}


}

UPDATE

I tried following Vamsi's answer but no luck.

Here is my actual VF/Controller

VF Page

<apex:page Controller="TestXXXController" showHeader="false" sidebar="false">


    <apex:form id="theform">
        <h2>Questions</h2>


        <apex:outputField value="{!pr.get(varstr)}"/>

    </apex:form>
</apex:page>

Controller

public class TestXXXController {

    public XXX__c pr{get;set;}

    public String varstr{get;set;}


    public TestXXXController()
    {
        init();
    }



    public void init()
    {

        XXX__c p = new XXX__c();
        String queryStr = 'Select '+CommonUsedClass.sObjectGetAllFields(p).trim()+' FROM XXX__c LIMIT 1';
        List<XXX__c> plist = new List<XXX__c>();
        plist = Database.query(queryStr);

        pr = plist[0];

        System.debug('p == > '+ pr);

        varstr = 'Schema.XXX__c.Name';


    }







    }

The above VF page gives me compile error as shown below

Could not resolve field 'get(varstr)' from <apex:outputField> value binding '{!pr.get(varstr)}' in page TestXXX1

Answer 1

VF PAGE:

<apex:page controller="SampleApex">
    FirstName : {!cObj['FirstName']}
     <br/>
    LastName : {!cObj[VarStr]}
</apex:page>

Controller :

public class SampleApex {

    public Contact cObj {get;set;}
    String varStr;
    public SampleApex () {
        cObj = new Contact (FirstName ='JAck', LastName='Cool');

        varStr = 'LastName';        
    }

    public String getVarStr () {
       return varStr;
    }
}

Assuming you want to display the value of a field in your visualforce page, You can use sObject.get(fiedName) in apex:outputField to pass in the fieldName dynamically and get the value displayed.

<apex:outputField value="{!YourObject.get(YourFieldNameVariable)}"/>
