Is Two Classes that call methods from each other possible?

Question

I have a class lets call it
gui and it has a method called addMessage that appends a string onto a text field
i also have a method called JNIinterface that has a method called
sendAlong Takes a string and sends it along which does alot of stuff
K the gui also has a text field and when a button is pushed it needs to call sendAlong
the JNIinterface randomly recieves messages and when it does it has to call AddMessage so they can be displayed
any way to do this??

Is Two Classes that call methods from each other possible?Do you mean like this?
   class A
     static void doB() { B.fromA(); }
     static void fromB() {}
   class B
     static void doA() { A.fromB(); }
     static void fromA() {}
.I doubt there is anyway to do exactly that. You can use an interface however.
   Interface IB
     void fromA();
   class A
     IB b;
     A(IB instance) {b = instance;}
     void doB() { b.fromA(); }
     void fromB() {}
   class B implements IB
     static void doA() { A.fromB(); }
     void fromA() {}
.Note that you might want to re-examine your design if you have circular references. There is probably something wrong with it.
