Need help on this MPG program

Question

Hi all,
The purpose of this program is listed in
// Inputs the miles driven and gallons used (both integers) for each tankful.
// Calculates and displays miles per gallon obtained for each tankful and print
// the combined miles per gallon obtained for all tankfuls up to this point.
// All results should be floating point. Use Scanner and sentinel-controlled
// repetition to obtain data from the user.
// Exercise 4.17 MPG.java
import java.util.Scanner;
public class MPG
     private int milesDriven;
     private int gallonsUsed;
     private float result;
     public void setMilesDriven( int miles )
     milesDriven = miles;
     public void setGallonsUsed( int gallons )
     gallonsUsed = gallons;
     public String getMilesDriven( int miles )
     return milesDriven; // error occurs here
     public String getGallonsUsed( int gallons )
     return gallonsUsed;
     public MPG( float result )
     result = gallons * miles;
     System.out.printf( result);
I try to compile this program, but the error I get is "incompatible types-found int but expected java.lang.String. How do I fix this, and how do I sentinel control? If you can help me with these two things, I'd appreciate it.

What has this got to do with algorithms?
