Question

I am trying pass a Hashtable as parameter into a method which itself passes that same table into another method:

     public class Recruiter {
               private WebDriver driver;
               private DataEntry d;
               private String password;

               public Recruiter(WebDriver driver){
               this.driver = driver;
               }

              public void createRecruiter(Hashtable<String, String> vars, String     preferences[]){       
               d.enterText(vars);
               driver.findElement(By.id("SAVE")).click();
        }

        Main:

                  Hashtable<String, String> vars = new   Hashtable<String, String>();

                       vars.put("DOB","02 Mar 1983");
                       vars.put("SURNAME","Release");
                       vars.put("FIRSTNAME","David");
                        vars.put("COMPANYNAME","Test Inc");


                   Recruiter recruiter = new Recruiter(driver);
                       recruiter.createRecruiter(vars, preferences);

However I keep getting a null pointer exception at: d.enterText(vars); what is the proper way to pass a Hashtable as a method parameter?

Just initialize DataEntry d before you use it. Something like:

d = new DataEntry();

inside the constructor.
