When I close my Java program it refreshes everything

Question

Label.setEnabled(true);

if (i == 0) {
    Label.setEnabled(false);
}

If i is equal to 0, it would not be enabled but when I close the program and open it again, it will be enabled instead of staying disabled.

By "close and open it again" do you mean, you halt the program (losing all non-persisted state) and then run another instance of it? — azurefrog, Jan 07 '16 at 23:14
runtime changes do not persist unless you provide a means of doing so, which I'm assuming you have not. — user1231232141214124, Jan 07 '16 at 23:15
You're not persisting the state of the value anywhere, so why do you expect it to be persisted? — David, Jan 07 '16 at 23:16

You need to write the current state of the program to a File. See How do I create a file and write to it in Java? on how to do that. Then, when you run the program, it needs to read from that file. You can do that like this:

File f = new File("PATH TO YOUR FILE");
try {
    Scanner s = new Scanner(f);
    String line1 = s.nextLine();
    String line2 = s.nextLine();
    //...
catch (IOException e){}
