Message:

StackOverflowError exception???

Posted by ping203 on February 22, 2002 at 11:46 AM

Hi,

You sure your program does not throw a StackOverflowError when you call setGUI???
public void setGUI(GeneManagerGUI gui) {
this.gui = gui;
manager.setGUI(gui);
}
I comment out the manager.setGUI(gui). I modify the GeneManagerGUI to String and run the following modified code, and it works fine. Did you ever call setGUI???

public class SingletonDemo {

private String gui;

private static SingletonDemo manager;
private static boolean initialized = false;

public SingletonDemo() {
this.manager = this;
initialized = true;
}

public void setGUI(String gui) {
this.gui = gui;
// manager.setGUI(gui);
}

public static SingletonDemo getGeneManager() {
if (!initialized) {
manager = new SingletonDemo();
initialized = true;
}
return manager;
}

public String getGUI()
{
return gui;
}

static void main(String args[])
{
SingletonDemo s = new SingletonDemo();
s.setGUI("A");
System.out.println(s.getGUI());
s.setGUI("B");
SingletonDemo b = SingletonDemo.getGeneManager();
System.out.println(b.getGUI());
}

}

Ping
