Preinitialization Pattern in Java 8 - Example 2

A.java

import java.util.function.Consumer;
public class A<T extends A> {
    
    public A(Consumer<T> preinitialization) {
        preinitialization.accept((T) this);
        initializeUsingSubclassMethod();
    }
    
}

B.java

import java.util.function.Consumer;
public class B extends A<B> {
    
    private String variable;
    
    public B(String variable) {
        super(self -> {
            self.variable = variable;
        });
    }
    
    public void methodUsedBySuper() {
        // do something with variable
    }
    
}
