Alan Kay. Many consider him the godfather of object-oriented programming. 51. Name the programming language that does not support polymorphism. The Ada language does not support polymorphism. 52. How much memory does a class consume? This is a trick question, because classes do not take up memory. Classes are just blueprints used to create objects. Only when objects are created is some memory consumed. 53. What was the first programming language developed as an OOP language? Smalltalk was the first OOP language created in the 70s. 54. Which popular OOP language does not support all types of inheritance? Java does not support multiple or hybrid inheritance. It only supports simple, multi-level and hierarchical inheritance. 55. Name some popular object-oriented programming languages. Some of the most used object-oriented programming languages are: C++ Python PHP Java Javascript Hire the best OOP developers by asking the right questions Object-oriented programming (OOP) is on the rise because it better solves real-world problems. The code is shorter and therefore easier to write, read, understand, modify, debug and maintain.
Additionally, OOP languages make it easier to create large, complex programs. For all these reasons, finding developers with the right experience and knowledge in OOP languages and principles is key for any organization that uses this programming to achieve its software development goals. One way to identify top talent is to ask the right object-oriented programming interview questions. We have provided you with a Brazil Phone Number Data complete list above to help you prepare for your interviews with candidates. But even before you start interviewing candidates, we advise you to use skills tests. Assess your candidates' knowledge early in the recruiting process to eliminate the need for resume screening and make your hiring process more objective and fair. Plus, comprehensive skills tests help you save time and money . For best results, combine our Object-Oriented Programming test with other position-specific programming tests such as the Data Structures test , Java Data Structures test , .NET test , and more. With TestGorilla as your testing and evaluation partner, you can quickly recruit talented OOP developers to help you achieve your company's goals.
while overloading is resolved at compile time. 37. Define what the abstract class is. In object-oriented programming, an abstract class is a class made up of abstract methods that are declared. However, these methods are not defined. If you want to use abstract methods in a subclass, you must define the subclass exclusively. 38. How would you create an instance of an abstract class? You can not. These instances do not have a full implementation. Therefore, you cannot create an instance of an abstract class. 39. Explain the difference between an exception and an error. An exception signals conditions that an application should catch. An error indicates a serious problem; an application should not encounter errors. 40. What is the difference between multilevel inheritance and multiple inheritance? Multilevel inheritance is when one class (which is a subclass) inherits from another class. Multiple inheritance is when a class inherits from two or more base classes. 41. Define Polymorphism is the quality of existing in more than one form. This means that you can give numerous definitions to an interface.
