You don’t need to create loads of constructors, all with the same code; you create only one, but have the derived classes call the base constructor: public class Base { public Base(Parameter p) { Init(p) } void Init(Parameter p) { // common initialisation code } } public class Derived : Base { public Derived(Parameter p) … Read more
You get this error because a class which has no constructor has a default constructor, which is argument-less and is equivalent to the following code: public ACSubClass() { super(); } However since your BaseClass declares a constructor (and therefore doesn’t have the default, no-arg constructor that the compiler would otherwise provide) this is illegal – … Read more
If you find a bug in your copy-paste code, you will need to fix it every place you did and hope you can remember them all (this also holds for changed requirements). If you keep logic in one place, it is easier to change when needed (so if you decide that the application needs updating, … Read more

Readability is more important for tests. If a test fails, you want the problem to be obvious. The developer shouldn’t have to wade through a lot of heavily factored test code to determine exactly what failed. You don’t want your test code to become so complex that you need to write unit-test-tests. However, eliminating duplication … Read more
Perhaps you don’t extend a controller but it is possible to extend a controller or make a single controller a mixin of multiple controllers. module.controller(‘CtrlImplAdvanced’, [‘$scope’, ‘$controller’, function ($scope, $controller) { // Initialize the super class and extend it. angular.extend(this, $controller(‘CtrlImpl’, {$scope: $scope})); … Additional extensions to create a mixin. }]); When the parent controller … Read more
