Most common adobe coding interview questions

Looking to prepare for the most common questions asked during coding interviews? Well, we have got you sorted. 

Here in this blog, we are going to discuss some adobe interview questions while enhancing your knowledge of some advanced SQL interview questions.

We will be discussing some conceptual questions about data structure algorithms and then move on to discussing the coding problems that are most commonly asked to solve in the interviews. 

These questions will surely help you summarize every important programming concept and serve as a perfect preparation resource for coding interviews.

So let’s get started: 

Top 10 programming interview questions that you should be practicing

If you are interviewing for the position of a developer then Programming Interviews are certainly very important for you. Regardless of the programming language that you have been practicing, it is expected that you familiarise yourself with the basic concepts of programming.

Coding skills can prove to be the deciding factor in a programming interview. We are going to discuss some common coding and abode interview questions that you should know in order to crack interviews for companies like Adobe, Facebook, Uber, and many more.

Now that we have covered the gist, let us discuss some important programming questions that will prepare you for your interviews with big-scale companies like Adobe, Google, and others.

Q1. What is Java? What are the features of Java?

1. Java is defined as a high-level programming language and is independent of all platforms; it is essentially a collection of objects. It was developed by Microsystems. There are a lot of applications and websites and games that have been developed using Java.

The features of Java are: 

OOP concepts- Object-Oriented Programming relates to languages that make the use of objects in programming.

Inheritance- This concept allows the construction of new classes for the existing ones which exhibit the same behavior.

Polymorphism- It uses a single symbol to depict multiple different types of data.

Abstraction- This process allows the programmers to only present the relevant data in order to increase efficiency.

Platform independent- This means that the byte code of Java can be run on all platforms.

High Performance- This means that the compiler in Java uses the “Just In Time Compiler”. 

Multi-threaded- It allows the optimal utilization of the CPU.

Q2. Why is the Java platform independent?

1. Java basically uses a virtual machine which makes it platform independent. The programs are compiled into bytecode and that bytecode is platform independent. The virtual machine in Java is what coordinates the differences between bytecodes for the various platforms.

Q3. Why is Java not fully Object Oriented?

1. Since Java supports primitive data types like long, byte, int, etc, it is not fully object-oriented. Java is the complete opposite of OOP because here we use data types like double, float, int, etc that are not object-oriented. 

Q4. What are the differences between C++ and Java?

Q5. What is Public static void main ?

1. Public: This is the access simplifier of vital methods. In order for Java to process this method, it should be public.

Static: If the main procedure is not constant, JVM will not be able to call it because there will be no object of the class that is available. When the runtime of Java starts,  no object of the class is available. That is  the reason, your main method should be constant. Hence, in this way, JVM will load the class into the memory. 

Void: Java's main method doesn’t return anything, that is why its return type is void. This has to be done to keep things simplified because once, main method gets processed and executed, the java program translates. Hence, there is no point in returning anything.

String[] args: Main method of Java accepts a single argument of a type String array. This is alternatively known as the Java command line arguments. 

Q6. How many Primitive Data types are there in Java?

1. In total there are 8 Primitive Data types. They are as follows:

• Boolean

• byte

• char

• short

• int

• long 

• float

• double

Q7. What are OOPs? What are the basic concepts of OOPs?

1. OOPs stands for the Object-Oriented Programming system. In OOPs Programs are tested as a collection of objects. It is a Programming Paradigm/Methodology. The programming paradigm is a concept used for solving problems using some programming language. 

The basic concepts of OOPs are

• Inheritance

• Encapsulation

• Polymorphism

• Abstraction

Q8. What is Class & Object?

1. Class: Class is a collection of Objects. Class is not a real-world component, it is just a template or blueprint. Class does not occupy spaces.

Objects: An object is a class instance and it is a real-world component. Object occupies Memory. Object consists of an Identity Name, State/ Attribute, and Behaviour.

Q9. What is Inheritance?

1. The inheritance of parent class into child class is known as inheritance. We can attain inheritance by making use of extended keywords. This child class will inherit all the public and protected properties and methods from the parent class.

class Animal

{

}

Class Dog extends Animal

{

}

Q10. What is Polymorphism?

1. Polymorphism is an object-oriented concept that relates to the ability of a function, object, or variable to take on multiple forms. When a programming language is depicting polymorphism, class objects that belong to the same hierarchical tree (they share a common parent class and are inherited by it) may have functions with the same name, but they have varying behaviors.

There are two types of Polymorphism:

• Compile time polymorphism (Static Polymorphism)

• Runtime Polymorphism (Dynamic Polymorphism)

Conclusion

Those were some of the basic questions which you will definitely encounter as your Adobe interview questions. These questions can also be asked as advanced SQL interview questions. 

As an applicant, you are requested to practice study materials and also refer to a few YouTube platforms which can guide you on the best ways to start and finish your preparation for the interview.

We suggest that you look through the preparation modules first and then you can focus on the questions that you have to prepare for the interview.
