As a JAVA beginner I ran in a bit a problem.
The program runs fine but everytime after several compilations there are JButtons created in the JButtons...
I think there is a big structural mistake but I can't seem to find where
Code of MainProgram.java
CODE
package wieIsHet;
public class MainProgram
{
private static boolean restart = true;
public static void main(String[] args)
{
Singleton singleton = new Singleton();
//for(;restart;)
//{
Game game = new Game();
game.start();
//}
}
}
Code of Game.java
CODE
package wieIsHet;
public class Game

private Lijst lijst;
private Singleton singleton;

singleton.geefLijst(lijst);
singleton.venster2.teken(1);
singleton.plaatsLabels();
}

try {
//lees de personen in

personen = new ArrayList<Persoon>();
gekozenPersonen = new ArrayList<Persoon>();
String s = lezen.readLine();
for(;s!=null;)
{
//splits in kenmerken en maak nieuw object persoon aan
String[] temp = s.split(";");
personen.add(new Persoon(temp[0], temp[1], temp[2], temp[3], temp[4], temp[5], temp[6], temp[7], temp[8]));
