SalesApp.java

Make a new Eclipse project for this objective named java4_Objective1. Put a copy of our current SalesApp class in this new project. So that it has no errors, comment out the lines about the SalesInterface:
// SalesInterface myInterface; 
// public void setInterface(SalesInterface myGUI){
 //  myInterface = myGUI;
 // }
Save this--there should be no errors now in this current version.
