Java Error - Actual and formal argument lists differ in length

Solution 1:

Well it's quite simple. Here's the declaration of setShippingDest:

public void setShippingDest(String inCustName, String inDestn)

And here's how you're trying to call it:

shipOrder.setShippingDest("Broome");

You've provided one argument, but there are two parameters? How do you expect that to work? You either need to provide another argument, or remove one parameter.

(I'd also strongly advise that you remove the in prefix from all of your parameters, and look into a real unit testing framework such as JUnit, rather than writing an enormous main method.)

Solution 2:

Also if you like to specify only the Customer Name, you could do so by overloading the method as

    public void setShippingDest(String inCustName)
    {
      return  setShippingDest(inCustName, defaultvalue1);
    }

See how to set default method argument values?
