Is there a reliable way to check if a trigger being fired was the result of a DML action from another *specific* trigger? C# does not have multiple inheritance precisely because Java does not allow it. Why is there no multiple inheritance in Java, but implementing multiple interfaces is allowed? So in a word, in Interfaces definition is done after implementation so no confusion. Consider a class A as a parent class, class B as a child class of class A and class C as a child class of class B. and when an object is created for class C, say obj as given above.

As we know, while constructor of a child class first constructor of its parent class is called. Can you explain why you say inheritance is overused? The compiler gets confused while mapping the function call with the definition, leading to a compile-time error. Let's see this with the help of a program. Thank you for your valuable feedback! The problem with multiple inheritance is that two classes may define different ways of doing the same thing, and the subclass can't choose which one to pick. One of my college instructors explained it to me this way: Suppose I have one class, which is a Toaster, and another class, which is NuclearBomb. Whether it says to display first or last alphabet???

Here, the text( ) methods from both the interfaces A and B are called separately, thereby eliminating the confusion about which classs method to call. I'm reading a book "Thinking in Java" that states the following about inner classes: Each inner class can independently inherit from an implementation. When an object of class C is created, constructors of all the three classes will be executed. Splitting implementations into interfaces with default methods for instance where each interface has one dependency say, SessionFactory sessionFactory(); and implement all logic pertaining to a SessionFactory, and say another interface implementing shit relating Session session(); will be way cleaner than having SessionFactory, and Session declared in one class.
