Diamond problem is a common problem occurred in Object Oriented Programming, while using multiple-inheritance. Consider the case where class C, is inherited from class A and class B. Suppose that both class A and class B have a method called foo(). Then when we are calling the method foo(), compil...

Inheritance is one of the main concepts in Object Oriented Programming (OOP). Using inheritance, we can model a problem properly and we can reduce the number of lines we have to write. Let's see inheritance using a popular example. Consider you have to model animal kingdom (Simplified animal kingdo...

Polymorphism is one of the basic concepts in OOP (Object Oriented Programming). Main idea of the polymorphism is that an object have the ability to take on different forms. To achieve that (polymorphism), we have two main approaches. Method overloading Occures when there are two or more meth...

Method overloading is the way of using polymorphism inside a class. We can have two or more methods inside the same class, with different input parameters. Difference of input parameters can be either: Number of parameters Type of parameters (Data type) Order of the parameters Let's take a ...

Abstraction is one of the main concepts in Object Oriented Programming (OOP). This is the process of hiding the implementation details for the outsiders while showing only essential details. In another words, Abstraction is a technique to arrange the complexity of a program. There are two basic typ...

Either you just want to test out Umbraco CMS, or host your site in a cloud service, you could sign up for a free trial at umbraco.com/cloud. The site you develop in the cloud service could be downloaded for local development or your own hosting later.

The Memory Model is difficult to understand, and difficult to apply. It is useful if you need to reason about the correctness of multi-threaded code, but you do not want to have to do this reasoning for every multi-threaded application that you write. If you adopt the following principals when wri...

Let's make a function to divide two numbers, that's very trusting about its input: def divide(x, y) return x/y end This will work fine for a lot of inputs: > puts divide(10, 2) 5 But not all > puts divide(10, 0) ZeroDivisionError: divided by 0 > puts divide(10, 'a') TypeE...

You can save the error if you want to use it in the rescue clause def divide(x, y) begin x/y rescue => e puts "There was a %s (%s)" % [e.class, e.message] puts e.backtrace end end > divide(10, 0) There was a ZeroDivisionError (divided by 0) from ...

If you want to do different things based on the kind of error, use multiple rescue clauses, each with a different error type as an argument. def divide(x, y) begin return x/y rescue ZeroDivisionError puts "Don't divide by zero!" return nil rescue TypeError put...

In a rescue clause, you can use retry to run the begin clause again, presumably after changing the circumstance that caused the error. def divide(x, y) begin puts "About to divide..." return x/y rescue ZeroDivisionError puts "Don't divide by zero!" y = ...

You can use an else clause for code that will be run if no error is raised. def divide(x, y) begin z = x/y rescue ZeroDivisionError puts "Don't divide by zero!" rescue TypeError puts "Division only works on numbers!" return nil rescue => e ...
