This has a better explanation of how to use a Scanner than I would write.

Yes. You should make a Scanner on listings.txt and use it to read in all of the property types. Something like:

while (scanner.hasNextLine()) propertyType.add(scanner.nextLine());

Oh, sorry, I misread the OP.

So, initially the Set propertyType will be empty. You don't know the different property types before you read listings.txt. So instead it looks like this:

Code: If you were reading through listings.txt normally (in notepad or whatever), and trying to construct an agentreport.txt file according to their spec, what would you do? Then code that.

I'm really at a point where I just don't know what the **** to do. It's not even covered in the ****ing book or course but I'm being asked to do it. What kind of ****ing piece of **** course is this? I'm so ****ing tired of this ****ing ****. There's no ****ing reason for this ****.

Here's my code:

while (console.hasNextLine())
{
property = console.nextInt();
type = console.next();
price = console.nextDouble();
agent = console.nextInt();
propertyType.add(type);
}

I don't understand how the **** this thing knows to disregard stuff and keep on moving and only entering in the things it needs. There's no ****ing explanation anywhere for this ****. I've ****ing had it.

Have you though about choosing some other profession? If you can't wrap your head around some algorithms, maybe you're better off forging steel?

Right now after I put in my input file when running it it then asks for the output file which it shouldn't be doing. If I take out the while statement it runs fine again, so I'm doing something wrong with the while statement.

dp

idMap.put(agent, price);

This line is wrong. Not in the sense of you are calling a function wrong, etc. but in the sense that you algorithm should do something different.

Imagine, for a moment, that you were doing this on paper and were creating (and updating) a table of agent/total price pairs as you read in the input file. If you saw agent ID 007, what would you do? Then do that in code.

There is, of course, also get().

You can't do this in one method call.
