public class Wrapperclass_controller
{
      list<Position__c> plist = new list<Position__c>();
      list<Candidate__c> clist = new list<Candidate__c>();
      list<Wrapper> wlist = new list<Wrapper>();
      public list<Wrapper> getLstwrapperstring()
      {
        plist = [select Position_Name__c,Location__c,Job_Description__c,Max_Pay__c from Position__c limit 10];
        clist = [select     First_Name__c,Last_Name__c from Candidate__c];
        //integer p = plist.size();
        for(integer i=0; plist.size();i++)
        {
           wlist.add(new Wrapper(plist[i].Position_Name__c,plist[i].Location__c,plist[i].Job_Description__c,plist[i].Max_Pay__c,clist[i].First_Name__c,
                                          clist[i].Last_Name__c));
        }
        return wlist;
      }
       public class Wrapper
       {
          public string pname{get;set;}
          public string pjdescription{get;set;}
          public string plocation{get;set;}
          public decimal pmaxpay{get;set;}
          public string cfname{get;set;}
          public string clname{get;set;}
          public Wrapper(string pname,string pjdescription,string plocation,decimal pmaxpay,
                        string cfname,string clname)
          {
             this.pname= pname;
             this.pjdescription = pjdescription;
