public class NewAndExistingController {
Public Account a{get;set;}public String accId;    public NewAndExistingController(ApexPages.StandardController controller) {
    try{    a =[select id,name,accountnumber,annualrevenue from account where id=:controller.getId()];    MyOrderPadController.staticVar =a.Id;   
 }catch(exception e){}   
  public PageReference click() {      
  PageReference openvfpage = New Pagereference('/apex'+'/XYZ);     openvfpage.setRedirect(false);  return openvfpage ;        }    public NewAndExistingController() {    }  

Controller: MyOrderPadController

  public class MyOrderPadController {  
      public Order__c order{ get; private set; 
       public static  String staticVar;   
        public String instanceVar {get; set;}   
            NewAndExistingController  test = new NewAndExistingController ();   
            public MyOrderPadController ()       {  
              instanceVar = staticVar;       
     public MyOrderPadController(ApexPages.StandardController sc) { 
           order = (Order__c)sc.getRecord();       
    public PageReference edit()      {  
              return null;            
     public PageReference reset() {       
       PageReference newpage = new PageReference(System.currentPageReference().getURL());          newpage.setRedirect(true);        
      return newpage; 
      public PageReference save()   
       TRY          {           
                      order.Name = 'Demo Test Order '+order.Order_Description__c;               order.Order_Description__c =order.Order_Description__c+':====>'+staticVar ;                order.Account__c = '0019000000NAr7bAAD';//for testing only                            IF(order.Conformation__c == TRUE){                                   
               INSERT order;                     PageReference newpage = new PageReference(System.currentPageReference().getURL());                    newpage.setRedirect(true);                    return newpage;           
                  }                                                            }                       catch(System.DMLException e)           {   
             ApexPages.addMessages(e);            SYSTEM.DEBUG('ERROR ORDER PAD CONTROLLER :'+e);            return null;          }        //  After Save, navigate to the default view page:        //return (new ApexPages.StandardController(order)).view();        return null;             }   }

Method 1

In NewAndExistingController try adding to Pagereference

PageReference openvfpage = New Pagereference('/apex'+'/XYZ+'?aid=';

You can refer this in the other controller as

order.Account__c = ApexPages.currentPage().getParameters().get('aid');
