Question

I am getting two errors from this program and I would like to know how I would fix this. I've tried on my own and I just don't know what to change.

Here are the errors:

Reimbursement_3_09.java:28: error: incompatible types: possible lossy conversion from double to int
    avgRe = (totalAmountgt0/ctrMiles);
                           ^
Reimbursement_3_09.java:29: error: incompatible types: possible lossy conversion from double to int
    avgMiles = (totalMilesgt0/ctrMiles);

Here is the program:

import java.io.*;
import java.util.*;
import java.text.*;

   int ctrMilesgt0 = 0;

Explanation / Answer

you, are declaring avRe , avgMiles as int . thats wrong.

int avgRe, avgMiles =0;

Instead you should decalre them double as below then you wont get error.

double avgRe, avgMiles =0;

Hope this helped!
