Help With I/O Exception Handling!

I am new to java programming and I need help with an assignment: I have most everything figured out, but I am stuck with a particular issue listed below. Here is what I am trying to accomplish and the issue I am having, I need to:

[Redacted because of copyright issue]

What the agentreport is suppose to look like is this:

Example agentreport.txt file:
COMMERICAL
FARM
LAND
RESIDENTIAL

101 600000.00
105 30000.00
106 200000.00
107 1040000.00
110 250000.00

what my agentreport.txt output looks like is this:

COMMERCIAL
FARM
LAND
RESIDENTIAL


101:500000.0
101:600000.0
105:30000.0
106:200000.0
107:1000000.0
107:1040000.0
110:250000.0

Basically I the totals are adding up correctly, but for some reason I can not get rid of the first 101 (101: 500000) and the first 107 (107:1000000.0). What can I do to remove those particular lines, but keep everything else as is? Any help on this would be appreciated! The current code is below and attached as a zipped project.

Please post your code in code tags.

The reason your results contain subtotals is because the following loop in the aValue() method occurs too early:

Code java:

---

        Set<String> keySet = aTotals.keySet();
        for(String key : keySet)
        {
            Number value = aTotals.get(key);
            info.add(key + ":" + value); 
        }

---

Where you have it now, the output string is being built incrementally, including the incomplete results. If you move the loop to just before the return statement in the aValue() method, the results will be improved.

use the code tags

[code] ...place code here... [\code]
that way it's easier for people to read your code and help direct you towards a solution.

Wow... That was an easy fix, thanks for the help! Sorry about not placing the code in tags, I will make sure to do that in the future, but appreciate the help regardless!!

And you're welcome regardless.
