Top 10 Questions for Fuller Interview

1. Can you explain the concept of data abstraction and how it is implemented in programming languages?

• Data abstraction is the concept of hiding the implementation details of a data structure from the user.
• This allows the user to interact with the data structure without worrying about how it is actually implemented.
• In programming languages, data abstraction is implemented through the use of classes and objects.
• A class defines the data structure and the operations that can be performed on it.
• An object is an instance of a class.
• When a user interacts with an object, they are only able to access the operations that are defined in the class.

2. What are the different types of access modifiers in Java?

Public

• Public access modifiers allow access to the class, method, or variable from any other class, even if the other class is in a different package.

Protected

• Protected access modifiers allow access to the class, method, or variable from any other class that is in the same package or a subclass of the class.

Default

• Default access modifiers allow access to the class, method, or variable from any other class that is in the same package.

Private

• Private access modifiers allow access to the class, method, or variable from within the class itself.

3. What is the difference between a constructor and a method?

• A constructor is a special method that is used to initialize an object when it is created.
• A method is a function that can be called on an object to perform a specific task.
• Constructors do not have a return type, while methods do.
• Constructors are called using the new keyword, while methods are called using the dot operator.

4. What is inheritance and what are the different types of inheritance?

• Inheritance is the ability for a class to inherit the properties and methods of another class.
• The class that inherits the properties and methods is called the child class or derived class.
• The class that is inherited from is called the parent class or base class.
• There are three types of inheritance: single inheritance, multiple inheritance, and hierarchical inheritance.
• Single inheritance is when a child class inherits from only one parent class.
• Multiple inheritance is when a child class inherits from multiple parent classes.
• Hierarchical inheritance is when a child class inherits from a parent class that inherits from another parent class.

5. What is polymorphism and what are the different types of polymorphism?

• Polymorphism is the ability for a method to behave differently depending on the context in which it is called.
• There are two types of polymorphism: method overriding and method overloading.
• Method overriding is when a child class defines a new implementation of a method that is inherited from a parent class.
• Method overloading is when a class defines multiple methods with the same name but different parameters.

6. What is the difference between an interface and a class?

• An interface is a contract that defines a set of methods that a class must implement.
• A class is a blueprint for creating objects.
• Interfaces do not have any implementation, while classes do.
• Classes can implement multiple interfaces, while interfaces can extend other interfaces.

7. What are the benefits of using a design pattern?

• Design patterns provide a reusable solution to a common problem.
• They can help to improve the quality of your code.
• They can make your code more maintainable.
• They can help you to avoid common pitfalls.

8. What is the difference between a linked list and an array?

• A linked list is a data structure that stores data in nodes.
• Each node contains a value and a pointer to the next node.
• An array is a data structure that stores data in a contiguous block of memory.
• Arrays are indexed, while linked lists are not.
• Linked lists are more efficient for inserting and deleting elements, while arrays are more efficient for accessing elements.

9. What is a hash table and how does it work?

• A hash table is a data structure that stores data in an array.
• Each element in the array is a key-value pair.
• The key is used to identify the value.
• When you want to add a new element to the hash table, you calculate the hash value of the key.
• The hash value is the index of the array where the element will be stored.
• If there is already an element stored at that index, the new element is added to a linked list.

10. What are the advantages of using a database?

• Databases provide a centralized way to store data.
• They allow you to access data from multiple applications.
• They provide data security and integrity.
• They can help you to improve performance.
