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. 

package salesGUI;

public class SalesApp {

  private int[] sales;
	
	private int salesBar;
	private int totalSales;
	
	private double average;
	private int minIndex = 0;

	SalesUserInterface myUserInterface; //SalesInterface myInterface;
