Sorry !!! I fogrgot to place the information with the code!!!!
I am having some trouble actually getting this done. I believe I have it correct so far. I just dont know how I am going to add the members in the arrays as well as removing them. I also can't figure out if I try to place a member in a space of the array that already has a member it outputs a println like "Sorry, please select another position. A member is already here". The sample output is below to show what I would need it to have. Yes, this is a project for school and I i'm not saying I need the exact code ( Read: do it for me), I would just need a little nudge in right direction. Please let me know if the code I have started to write is wrong already... Thank you for the help in advance!
The number of rows they have to stand on. The maximum number of rows is 10. The rows are labelled with capital letters, 'A', 'B', 'C', etc.
For each row, the number of positions in the row. The maximum number of positions is 8. The positions are numbered with integers, 1, 2, 3, etc.
The conductor then starts assigning people to positions, but is constrained by weight limits: Musicians, fully clothed and holding their instruments, weigh from 45kg to 200kg, and the total weight of a row may not exceed 100kg per position (e.g., a row with 5 positions may not have more than 500kg of musicians on it). The conductor wants a program that allows musicians to be added and removed from positions, while ensuring the constraints are all met. At any stage the conductor wants to be able to see the current assignment - the weight in each position (0kg for vacant positions) and the total & average weight for each row.
The program must be menu driven, with options to:
Add a musician (by weight) to a vacant position.
Remove a musician from an occupied position.
Print the current assignment.
Exit (so the musicians can start playing)
---------------------------------------------------
The program must be reasonably idiot proof:
Menu options must be accepted in upper and lower case.
Row letters must be accepted in upper and lower case.
All input must be checked to be in range, and if not the user must be asked to input again.
You may assume that numeric input will be syntactically correct.

You have a 2d array (rows / positions). All its entries will initially be zero. When you place a musician you put their weight into the corresponding entry. So it's really easy to see if a position is empty (the entry is still zero) or occupied (the entry is a non-zero weight). And to remove a musician just set the entry back to zero.
ddnpresident 2 Newbie Poster
So when the program says " There is already a musician here" would it be something like an if statement if an index value is greater than 0 than print "There is already a musician here"? I am just super confused on how to make it say that if I already placed a value there.
Edit: I appreciate the help! Also my different methods on the bottom I don't know how to go about coding them. This is just so frustrating for me! I have tried looking it up in the search function on this site as well as others and I just to get how I am going to select a certain position to add it to.
Example:
(A)dd, (R)emove, (P)rint, e(X)it : a
Please enter row letter : b
Please enter position number (1 to 4) : 4
Please enter weight (45.0 to 200.0) : 55
****** Musician added.
JamesCherrill 4,733 Most Valuable Poster Team Colleague Featured Poster
It really is that simple, eg let's suppose the2D array is called weights, then if the user asks if row B, position 4 is occupied, your test is
if (weights[1][3] > 0)
(remember Java arrays start at element 0, not element 1)

Thank you for the help so far. I will try to finish up a bit more code and get something more complete to look at. This is a final project for a beginners java class. The teacher is not very informative when describing things so I have to resort to self teaching to try to get through this class. My TA is horrible and is no help...
ddnpresident 2 Newbie Poster
Did you have a chance to look at my code so far? Just wondering if Im going good so far on it. I have not tried to run anything because I don't have the program complete yet. I am not trying to be a bother at all, I really don't have anyone else to look it over.
JamesCherrill 4,733 Most Valuable Poster Team Colleague Featured Poster
Sorry, I'm out now until tomorrow. Do try to run your code - the sooner you run it the sooner yo will find the bugs. Just hard-code values for anything that you need but haven't sorted yet. Trust me, real programmers test early and test often.
See you tomorrow.

Still working on this. Please any help in any of the things i have commented below would help me out greatly. I dont need the exact code written out for me . I am not looking for anyone just flat out do my work, I just need maybe a hint in some places. I have really tried hard and I seem to be getting no where further to asnwer some of my questions. If anyone has the time to look through my current code and give suggestions or/and help with adding onto my program, I would appreciate it greatly, I will try to soak in the information as well as a sponge. Thans in advance!

Thanks for sharing your final solution. I had a quick scan thru the code and can't see anything objectionable, so well done. (Rather than static methods I would generally prefer to see an instance-based implemention, but in this case it really doesn't matter.)

This was the only problem I found:-
For exiting the program, the command is not case sensitive. When I press 'X' it does not exits the program it just breaks the loop and continues. So check the condition of the do while loop in displayMenu method.
