You have to provide a way for each object to know about the 
other.  That means that the Frame which has to access methods
in the other has to have a reference to that other frame:

public class Frame1 extends ... {

  public Frame2 frame2;
  
  // constructor with no parameters -- JBuilder needs such a constructor
  // for visual designer.
  public Frame1() { ... }

  // You call this method from the application object, or some other
  // object which "knows" about both frames.
  public void setFrame2(Frame2 aFrame2) {
     this.frame2 = aFrame2;
  }

  // a method which calls a method in frame2
  void doSomething() {
     if ( aFrame2.isOK() ) 
        ...;
  }

} // end of Frame1

public class Frame2 extends ... {

  // Zero-parameter constructor.
  public Frame2() { ... }

  // Provide a "public" method "isOK()" so that other classes can call it.
  public boolean isOK() {
     // maybe ... you implement it.
     return false;
  }
  // ... more methods.
}


That's it.
