An OOPS interview can be a tough nut to crack for even the most seasoned IT professionals, especially if you are not well prepared. To help you in your quest to score that coveted job<\/span>.

Here’s a list of the best OOPS (Object Oriented Programming System) Interview questions along with their answers. <\/strong><\/span><\/h2>

1. Can you explain the different types of Inheritance? <\/span><\/strong><\/span><\/h3>

There are four main types of Inheritance in OOPS as listed below: <\/span><\/p>

• Single Inheritance: This includes one base class along with one derived class. <\/span>
• Hierarchical Inheritance: This inheritance class includes one base class as well as multiple derived classes of the same base class. <\/span>
• Multilevel Inheritance: This includes a class derived from a derived class. <\/span>
• Multiple Inheritance: This class includes several base classes as well as a derived class. <\/span><\/p>

2. Explain the concept of a hashtable. <\/span><\/strong><\/span><\/h3>

Hashtable is used to store multiple items. Each of these items is linked with their own unique string key and can be accessed using the key associated with it. <\/span><\/p>

3. What is Association? <\/span><\/strong><\/span><\/h3>

Association can be described as a relationship that exists between two objects with multiplicity. <\/span><\/p>

4. Can you touch upon the core concepts of OOPS? <\/span><\/strong><\/span><\/h3>

The core concepts of OOPS are as below: <\/span>
• Encapsulation <\/span>
• Polymorphism <\/span>
• Inheritance <\/span>
• Abstraction <\/span>
• Composition <\/span>
• Association <\/span>
• Aggregation <\/span><\/p>

5. Can you list out some examples of tokens?<\/span><\/strong><\/span><\/h3>


<\/span><\/strong><\/span>
Here are some common examples of tokens: <\/span>
• Keywords <\/span>
• Commas <\/span>
• Constants <\/span>
• Identifiers <\/span>
• Brackets <\/span>
• Operators <\/span><\/p>

6. Can you describe Polymorphism and list out the different types of Polymorphism? <\/span><\/strong><\/span><\/h3>

Polymorphism can be termed as the ability to take on more than one form. In OOPS, Polymorphism means a single interface with multiple implementations for a certain class of action. <\/span><\/p>

Polymorphism can further be classified into two distinct types: <\/span>
• Static <\/span>
• Dynamic
