copied!<p>The code for an ITD introduction is no different that the code that you would add to a class directly. So without member initialization code in your introduced constructor, members will , of course, remain uninitialized. So you need to change you code in Q1 as follows.</p> <pre><code>public Child.new(String name, int age) { this.name = name; this.age = age; System.out.println("Child Name:" + this.name); } </code></pre> <p>As for Q2, it works fine for me.</p> <pre><code>class Parent { public void init() { System.out.println("P.init"); } } class Child extends Parent { } aspect Intro { public void Child.init(){ super.init(); System.out.println("C.init"); } } public class Main { public static void main(String[] args) { Child c = new Child(); c.init(); } } </code></pre> <p>prints:</p> <pre><code>P.init C.init </code></pre> <p>Changing the introduced method to something other than <code>init</code> works too (to match your code).</p> <p>Regarding your comment: I fail to see what difference you have made in Q1. Sorry, I don't get it.</p> <p>As for Q2 part of your comment, constructor arrangement works for me:</p> <pre><code>class Parent { protected String name; public Parent(String name) { this.name = name; } } class Child extends Parent { int age; public Child(String name) { super(name); } } aspect Intro { public Child.new(String name, int age){ super(name); this.age = age; System.out.println("this.name: " + this.name + " this.age: " + this.age); } } </code></pre> <p>prints <code>this.name: myname this.age: 2</code></p>
