TCE Software Developer Interview Questions and Answers

Advanced OOP concepts include polymorphism, encapsulation, inheritance, and abstraction, enhancing code reusability and maintainability.

• Polymorphism: Allows methods to do different things based on the object it is acting upon. Example: Method overriding in subclasses.

• Encapsulation: Bundles data and methods that operate on the data within one unit (class), restricting access to some components. Example: Private var...read more

Access specifiers determine the level of access to classes, methods, and variables in object-oriented programming languages.

• Access specifiers include public, private, protected, and default.

• Public allows access from any other class.

• Private restricts access to only within the same class.

• Protected allows access within the same package and subclasses.

• Default (no specifier) restricts access to only within the same pac...read more

Stack overloading occurs when the stack memory is exceeded due to excessive function calls or large local variables.

• Occurs when the stack memory limit is exceeded

• Caused by excessive function calls or large local variables

• Can lead to stack overflow error

OOPs concepts are fundamental principles of object-oriented programming, including inheritance, encapsulation, polymorphism, and abstraction.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Polymorphism: Ability to present the same interface for different data types.

• Abstraction: Hiding the complex ...read more

A class is a blueprint for creating objects, while an object is an instance of a class.

• A class defines the properties and behaviors of objects.

• An object is a specific instance of a class.

• Objects can have their own unique values for properties defined in the class.

• Classes can be used to create multiple objects with similar characteristics.

• Example: Class 'Car' defines properties like 'color' and 'model', while an ob...read more

4 key OOP concepts are encapsulation, inheritance, polymorphism, and abstraction.

• Encapsulation: bundling data and methods that operate on the data into a single unit (class)

• Inheritance: allows a class to inherit properties and behavior from another class

• Polymorphism: ability for objects to be treated as instances of their parent class or their own class

• Abstraction: hiding the complex implementation details and sho...read more
