Hello, I have an assignment to create a Java application that receives an input string such as "buy 100 share(s) at $20 each;buy 50 share(s) at $25 each;sell 135 share(s) at $37 each". The code is supposed to return the capital gain/loss and is supposed to calculate it using a FIFO data structure. This would be calculated such as 100*17 + 35*10.

I have most of it coded, and everything is currently working up to the point of parsing each string (semi colon delimited) into the needed elements and adding them to a queue.

The problem I'm having is figuring out how to remove the elements in a way that calculates the capital gain/loss.

Does any one have any pointers of where to start with this algorithm?

Thanks in advance for any help you may have!

This program feels very unrealistic to me. The answer all depends on how you have your code setup.

Thank you for your reply, sorry if my post was confusing...I didn't do a very good job at explaining the problem/assignment.

I think I figured it out (I'm just getting an index error on my arraylist I'm using to track the buying and selling of shares).

If I can't figure out how to fix my code so I don't keep getting the error I will post another question.

Thanks again for taking the time to view and/or respond to my question.

So... it's just a queue.

total = 0
for 100: equeue 20
for 50: equeue 25
for 135: total = total + ( 37 - dequeue )

Can't really offer more without code. Good luck.
