2D Array newb

[The Midnighter]

Alright, so basically here's what's supposed to happen.
It's an Airline reservation system, basically taking a row of 10 seats, 1 isle, 1 window. Yes, there's only one row. xD So 5 seats isle, 5 seats window.. Here's the code I have so far:

 
package airlineconsole;
 
import java.io.*;
 
public class Main
{
    private static BufferedReader stdin = new BufferedReader(
            new InputStreamReader( System.in ) );
 
    /** Creates a new instance of Main */
    public Main()
    {
    }
 
    public static void main(String[] args) throws IOException
    {
        // Init
        boolean[][] array = new boolean[5][5];
        // end Init
 
        System.out.println("Welcome! Please enter the style seating(1 for Economy, 2 for First Class): ");
        String seatStyle = stdin.readLine();
        int seatStyleNum = Integer.parseInt( seatStyle );
 
        for (int i=0;i<5;i++)
            for (int j=0;j<2;j++)
            {
                while ((array[i][j]) == false)
                {
                    System.out.println("Seat " +array[i][j]+ " Reserved.");
                    array[i][j] = true;
                }
            }
    }
}
 
 

My problem is, this goes through the entire array, and prints out EVERY seat. But I don't understand why it's doing that, since I set the value to TRUE after the fact?

[Ganon11]

It's printing every seat because that's exactly what you are telling it to do. Your boolean array is initialized to all false values, and then, inside your loop (which checks every seat), it says, IF the current boolean value is false, THEN print this. Well, every place is false, so it prints every time.

BTW, your loop is ineffective here, as it will always execute once and ALWAYS once. You should just use an if statement.

                        array[0][j] = 1;
                        finished = true;
                        break;
                    }
                    if (finished == true) break;
                }
            }
            else if (seatStyleNum == 2)
            {
                for (int i = 0; i<5; i++) // I is the Isle seat
                {
                    if (array[i][0] == 0)
                    {
                        System.out.println("Isle seat " +array[i][0]+ " reserved.");
                        array[i][0] = 1;
                        finished = true;
                        break;
                    }
                    if (finished == true) break;
                }
            }
            else
            {
                System.out.println("1 / 2 are the only valid options.");
            }
        }
    }
}
 

Now, here's my NEW problem:

It's like, it's not filling the array with "1", because it keeps printing "Window seat 0 reserved"

A buddy of mine fixed the problem, had the initlization wrong >.< Was creating the array inside the loop geeez..........
