Wrapper class line are highlighted.

public class AccountSearchController{

public List<Contact> ContactObjects {get;set;}
public List<Account> AccountObjects {get;set;}
public List<Account> AccountObjectsx {get;set;}
public Account AccObj {get;set;}
public Contact ContactObj {get;set;}
private String soql {get;set;}
//Our collection of the class/wrapper objects cContact 
public List<cContact> contactList {get; set;}
public ApexPages.StandardSetController con{get; set;}
