Question

I’m working on a small application that handles finances and so on. The development environment i use is netbeans.

I have a methods-class (called Methoden) where I have stored all the methods, a data-class and the frame-class (called Fenster1)

To get some input I defined a method in the method-class and tried to access it with

Methoden m = new Methoden();
...
buttonAction {
   m.getInput();
}

Code is fine, no errors at all. But when I try to start the application it takes a while and then this error appears:

Exception in thread “AWT-EventQueue-0” java.lang.StackOverflowError
at sun.awt.Win32GraphicsConfig.getBounds(Native Method)

at haushaltsbuch.Fenster1.(Fenster1.java:19)
at haushaltsbuch.Methoden.(Methoden.java:16)

Now: how can I fix this error to make everything running fine?

seems resolved.

in Fenster1 there was Methoden m = new Methoden();
while in Methoden there was Fenster1 f = new Fenster1();

Answer 1

A stack overflow exception means (usually) that a function recursively calls itself. I would suspect Methoden#getInput() does this.
