Practical Java Praxis 68: Use Care When Calling Non-final Methods from ConstructorsPeter Haggar
With the JavaScript file loaded, we can call the greet function in the constructor as follows: MainView.java public MainView() { add(new H1("It works!")); callJsMethodInTheBrowser(); } private void callJsMethodInTheBrowser() { getElement().executeJs("greet("client")"); } The get...

Calling Java from JRuby All the following examples can be "run" either from the command line, or by using jirb_swing, the Swing-based IRB console that comes with JRuby. You can start jirb_swing like $ jruby -S jirb_swing.A special require 'java' directive in your file will give ...
Let's enrich our Java class with a constructor and a simple method, in example 5: Class MyTest { ... private int uid; // private data of the object: it's ID public MyTest() { // constructor uid = magic_counter++ * 2; } public void showId() { // simple method that shows ...
In C++, we can derive some classes. Sometimes we need to call the super class (Base class) constructor when calling the constructor of the derived class. Unlike Java there is no reference variable for super class. If the constructor is non-parameterized, then it will be called automatically ...
(Note that in this article I talk about methods and method calling, but the very similar statements can be said about fields, constructors.) If you can callsuper.method()to access the parent’smethod()even if the actual class has overridden it why can not you callsuper.super.method()?
