15 MCQ based on java and data structure
I appeared for an interview in Dec 2016.
The main OOPs concepts are encapsulation, inheritance, and polymorphism.
Encapsulation: bundling of data and methods into a single unit (class) to hide implementation details.
Inheritance: ability of a class to inherit properties and methods from another class.
Polymorphism: ability of objects of different classes to be treated as objects of a common superclass.
Polymorphism is the ability of an object to take on many forms. Runtime polymorphism is achieved through method overriding.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
Static polymorphism is achieved through method overloading.
Runtime polymorphism is determined at runtime based on the actual type of the object.
Static polymorphism is determined at compile-time based on...
The static keyword in Java is used to create variables and methods that belong to the class rather than instances of the class.
Static variables are stored in the static memory area, also known as the method area or permanent generation.
Static variables are shared among all instances of a class.
Static methods can be called without creating an instance of the class.
Static variables and methods can be accessed using the c...
The abstract keyword is used in object-oriented programming to declare a class or method as abstract.
An abstract class cannot be instantiated and can only be used as a base for other classes.
An abstract method is a method without a body, and it must be implemented by any concrete subclass.
Abstract classes can have both abstract and non-abstract methods.
Abstract methods are used to define a common interface that all sub...
Multiple inheritance is when a class inherits from more than one base class. Multilevel inheritance is when a class inherits from another derived class.
Multiple inheritance allows a class to inherit attributes and behaviors from multiple parent classes.
Multilevel inheritance involves a chain of inheritance where a derived class inherits from another derived class.
In multiple inheritance, conflicts may arise if two base...
Java implements multiple inheritance through interfaces.
Java does not support multiple inheritance of classes.
Instead, it allows multiple inheritance of interfaces.
A class can implement multiple interfaces, inheriting their methods and constants.
Interfaces provide a way to achieve multiple inheritance without the complexities of class inheritance.
Example: class A implements Interface1, Interface2 { ... }
An interface is a contract that defines a set of methods that a class must implement. It is not abstract.
An interface provides a way to achieve multiple inheritance in Java.
It allows for loose coupling between classes.
Interfaces can have constants and default methods.
A class can implement multiple interfaces.
Interfaces are used to achieve abstraction and provide a common behavior for classes.
String is immutable because it ensures data integrity and thread safety. StringBuffer and StringBuilder are mutable alternatives.
String is immutable, meaning its value cannot be changed once created.
