Prepare Interview with Confidence
Interview questions on Core Java asked in multinational corporations (MNCs), along with explanations: Explain the concept of Object-Oriented Programming (OOP) and its principles in Java. Object-Oriented Programming (OOP) is a programming paradigm that revolves around the concept of objects, which encapsulate data and behaviors. Java is an object-oriented programming language, and it implements several OOP … Read more

To construct a robot we need following parts− a. Power Supply Generally, robots are powered by batteries, solar power, hydraulic. b. Actuators Basically, we … Read more
What is the use of computer vision in AI? Computer vision is a field of Artificial Intelligence that is used to train the computers so that they can interpret and obtain information from the visual world such as images. Hence, computer vision uses AI technology to solve complex problems such as image processing, object detections, etc. … Read more
What do you understand by fuzzy logic? Fuzzy logic is a method of encoding human learning for AI. It imitates the decision making process of humans through IF-THEN instances and the digital values of YES and NO. It is based on degrees of truth. Dr. Lotfi Zadeh of the University of California at Berkeley was … Read more
Is Java Pass by Reference or Pass by Value? The Java Spec says that everything in Java is pass-by-value. There is no such thing as “pass-by-reference” in Java. The difficult thing can be to understand that Java passes “objects as references” passed by value. Which class is the immediate superclass of the Container class Component. … Read more
What are roles in AI career? Software analysts and developers. Computer scientists and computer engineers. Algorithm specialists. Research scientists and engineering consultants. Mechanical engineers and maintenance technicians. Manufacturing and electrical engineers. Surgical technicians working with robotic tools. Military and aviation electricians working with flight simulators, drones, and armaments. Explain the objective and related terminology used … Read more
Explain what LINQ is. LINQ is an acronym for Language Integrated Query, and was introduced with Visual Studio 2008. LINQ is a set of features that extends query capabilities to the .NET language syntax by adding sets of new standard query operators that allow data manipulation, regardless of the data source. Supported data sources are: … Read more
When does regularization becomes necessary in Machine Learning? Regularization becomes necessary when the model begins to ovefit / underfit. This technique introduces a cost term for bringing in more features with the objective function. Hence, it tries to push the coefficients for many variables to zero and hence reduce cost term. This helps to reduce … Read more
What is difference between HashMap and HashSet HashSet : HashSet does not allow duplicate values. It provides add method rather put method. You also use its contain method to check whether the object is already available in HashSet. HashSet can be used where you want to maintain a unique list. HashMap : It allows null for both key … Read more
What are aspects of robotics? Basically, robots have mechanical construction. That is to form or shape designed to accomplish a particular task. Also, it contains electrical components. That is a use of power and control the machinery. Basically, it contains some level of a computer program. Also, it determines what, when and how a robot … Read more
