I don't know if you understood what I said, but take a look on this example:
public class Main {
public static class A {
public void methodA() {
System.out.println("A.methodA()");
}
public void methodB() {
methodA();
System.out.println("A.methodB()");
}
}
public static class B extends A {
public void methodA() {
System.out.println("B.methodA()");
}
public void methodB() {
System.out.println("B.methodB()");
super.methodB();
}
}
public static void main(String[] args) {
B b = new B();
b.methodB();
}
}
The output will be:
B.methodB()
B.methodA()
A.methodB()
The implementation that I did in the javascript library works exactly like this.
