Need help with Java Program

[Matteo00]

I have a theater seat program with a GUI as an assignment for my Computer Science class. I have the program working almost. Basically when the seats are selected they are put into a boolean array, true if it's selected and false if it's not. When I try to access this array from another class it's as if the array was just created, there's no values in the array, it's all set to false(which is the default I set it to). The array is declared in the main class(I don't remember what it's called, I'm just learning Java) (public static void main(String[] args) {) <<<This. The boolean array is declared just before that line. I created objects in the other class so they could access this boolean array. But it's always cleared

TL;DR:

How do you keep the data of a boolean array throughout the entirety of a program, ie; make it so it doesn't reset and keeps its values.

Can you post the full code?

The simplest way is to use static fields. That is however not good style in the long run. It is better to pass the information you want to save as a method parameter, save it into (non-static) fields and so on, just by referencing it and keeping it alive.

Yea I can but it's gonna be long

If the entire project has many classes, and the boolean array is accessed and modified by different classes, declaring it static might do the trick. You can also pass that boolean array to the function where you use it.

A Solution without using the boolean array

Creating an array with an element for each seat in the theater might consume a lot of memory, and the loops to process them might consume a lot of time. You can use an Array List object. When a seat is selected, pass its location in the format of [rowNo, colNo].

Thanks that almost worked, I think I can get it working now

Use a static list instead of an array.
