Can a java subclass's private final field be initialized before the super constructor completes?

Question

I have a pair of classes looking like this;

public abstract class Class1 {

//...

    public Class1() {
        //...
        function2();
        //...
    }

         


        

Answer 1

Your design is an instance of the "leaked this problem" and is an anti-pattern in Java. You should never call out to a publicly overridable method from a constructor.
