I am doing a program in which there are 8 planes seats the user gets to choose whgich seat they want.
I created the GUI buttons and what not (fairly easy), but I wanted to make an array....I'm rambling here, because I can't do this program the way I want.

okay here it is

String Nums []={"1","2","3"};

there is my array, so lets say the user selects seat 2 which would be Nums[1], how would I restrict seat 2 from being selected again, and if all the seats are selected, how would I tell the user all the seats are full.

Why not use the array as a sort of existence table. For example, you would have an array of boolean designating the number of seats:
Now for each index i, i + 1 is the seat number. When the seat is occupied, set occupied[i] to true. Then if the user tries to choose an occupied seat, all you need to do is test for true.

There are quite a few ways to test if all of the seats are taken, but by far the easiest is to maintain a counter that counts the number of occupied seats. If the counter is equal to the size of the array, the plane is full.

I would definately take Narue's suggestion of usign a boolean array, but if you are also familiar with multi dimensional arrays you could also take a but further and try and do this:

int numOfColumns = 40;
int numOfRows = 8;
boolean[][] seatTaken = new boolean[numOfColumns][numOfRows];

so now seatTaken[4][5] would represent the seat in column 4, row 5 of the plane, etc, etc.... :cheesy:

>so now seatTaken[4][5] would represent the seat in column 4, row 5 of the plane
Column 5, row 6 of the plane. Because airlines don't use zero-based indexing, there's a difference between the pysical rows and columns and the logical rows and columns. It's best to avoid fencepost errors, right?

Can you tell me why I get an error within my actionPerformed method please
