    Default Cinema Seating arrangment

    Hey, I'm wondering if anyone can help me, Im trying to create a simple cinema seating arrangement, where the x's are seats take and the o's are free. Problem is I cant seem to get the 0's to start where the X's finish. I'm new to java so what you see is the extent of my ability so far. Thanks for any help you can give at all!Here is what I haveso far;

    import java.util.Scanner;
     
    public class Exercise4iv
     
     
     
     
    {
     
    public static void main (String[] args)
     
    {
     
     
     
    int seats, taken, available, i, k;
     
     
    seats = 50;
    taken = 28;
    available = seats-taken;
    i=0;
    k=0;
    while( i<=taken){ 
    i++;
    System.out.print("\t X");
    if(i%8==0 )System.out.println();}
     
    while( k<=available){
    k++;
    System.out.print("\t O");
    if(k%8==0) System.out.println();}
    }}
    Here is what i want it to look like for example

    X X X X X X X X
    X X o o o o o o
    o o o o o o o o
    o o o o o o o o
    o o o o o o o o

    Do you know or can you use arrays yet?

    Use a single loop that iterates seats number of times. Inside have an if statement when counter reaches taken swap over to printing o's.

    If you know how to use arrays, then this problem becomes very, very simple.

    Why do you need an array?
    What part of my simple algorithm above (which doesn't need an array) didn't you understand?

    No one said "need" before post #5, but it's important to understand what tools can be used in the design before wasting time guessing.

    Frankly, I think we care more than the OP.

    Both you and aesguitar suggested using an array which is overkill for this. You would need two loops one to fill the array and one to print it. If you can work out the logic of how to fill the array with X's or O's then why not just print them to the screen instead of inserting them into an array?

    I'm not gonna argue an incomplete problem statement with you. In fact, I won't argue anything with you. Your idea is great, and everyone else's sucks.

    I asked my question, because I suspect that the status of the seats will change or will need to change as tickets are bought at which time simply printing patterns in bifurcated loops will be a difficult design to update with the current seating status. But I was thinking ahead, assuming facts not yet in evidence, and possibly wrong.

    Yes a better solution would be to use a 2D array and allow patrons to choose which seats instead on allocating them linearly.
