Classes and Objects Help

[collin389]

I have two classes class A and class B. class A creates on object of class B by going: B b = new B(); Inside class B, there is an action listener that I want to run a method that is inside class A. I cant just create another object A from class b and run the method there, it has to be from from the class A that is the parent to class B. Any ideas? Thanks

You can always pass a reference of A into the B object and use that reference. For e.g.,

public class A {
  B b;
  
  A() {
    b = new B(this);
  }
}

public class B {
  A a;
  
  public B(A a) {
    this.a = a;
  }
}
