Problem:
-Create a java program in which an airline can keep track of it's seating assignments.
-Using the InputDialog Method ask the user how many people will be coming aboard the plane.
- The plane consists of only 5 seats.
- Keep assigning people to the seats in the plane until all seats are filled.
-Once every seat is filled tell the user no more seats are avaiable.
Question:
Ok I have a simple question. How do I make it so that I can read the elements inside an array and if any one of them gets to or above 5 it stops letting me input numbers. For example, let's say I have 2 in index 0 and 3 in index 1, that makes 5 so I don't want to store anything more and when i go and input another number it doesn't let me. Another example, let's say index 0 holds the number 5 then it won't let me progress to index 1 because I already have the desired number which is 5. I hope that was pretty clear. This is for a plane assignment seating program with only 5 seats. This is what I have so far:
[source lang="java"]import javax.swing.JOptionPane;
public class Seating {
public static void main(String args[]) {
int seatstaken = 0;
int seats[] = new int [5];
do{
JOptionPane.showMessageDialog(null, "Welcome to Coqui Air!");
for ( int i= 0; i < seats.length; i ++){
seats = Integer.parseInt(JOptionPane.showInputDialog("How many people will be traveling with you today?"));
}
for (int i = 0; i
}
}while(seatstaken <5);
if (seatstaken > 5){
JOptionPane.showMessageDialog(null, "Plane full.");
}
}
}[/source]
It's pretty terrible code, but I'm a beggining java programmer and my proffessor did not explain this subject of arrays at all, he just gave us a very brief example and it did not clear up my doubts whatsoever. Also in his example he uses a scanner for input, the problem requires that we use the JOptionPane user input method. Any help is appreciated as I have been trying to solve this since 4 pm my time.
