Polymorphism in Java

๐Ÿ“ Polymorphism allows a single interface to be used for different types of actions.
๐Ÿ“ It is of two types:

Method Overloading (Compile-time Polymorphism)

Method Overriding (Runtime Polymorphism)


Method Overloading (Same method name, different parameters)

class MathOperations {
int add(int a, int b) {
return a + b;
}

double add(double a, double b) {
return a + b;
}
}

Method Overriding (Same method in parent and child class)

class Animal {
void makeSound() {
System.out.println("Animal makes a sound");
}
}

class Dog extends Animal {
void makeSound() {
System.out.println("Dog barks");
}
}

Which programming language should I use on interview?

Companies usually let you choose, in which case you should use your most comfortable language. If you know a bunch of languages, prefer one that lets you express more with fewer characters and fewer lines of code, like Python or Ruby. It keeps your whiteboard cleaner.

Try to stick with the same language for the whole interview, but sometimes you might want to switch languages for a question. E.g., processing a file line by line will be far easier in Python than in C++.

Sometimes, though, your interviewer will do this thing where they have a pet question thatโ€™s, for example, C-specific. If you list C on your resume, theyโ€™ll ask it.

So keep that in mind! If youโ€™re not confident with a language, make that clear on your resume. Put your less-strong languages under a header like โ€˜Working Knowledge.โ€™

Starting your journey in Java development is a solid foundation in the software development world. As you gain experience, you might find new areas of specialization that pique your interest:

โ€ข Backend Development: If you enjoy building server-side applications and working with databases, diving deeper into backend development might be your next step. Youโ€™ll focus on creating robust and scalable systems using Java frameworks like Spring or Hibernate.

โ€ข Android Development: If youโ€™re excited about creating mobile applications, specializing in Android development could be your calling. Java has been a core language for Android, and mastering it will allow you to build powerful apps for millions of users.

โ€ข Enterprise Application Development: If youโ€™re interested in creating large-scale applications for businesses, focusing on enterprise Java (Java EE) might be the right path, where youโ€™ll work on complex systems that serve thousands of users.

โ€ข Cloud Computing: If you're fascinated by cloud technologies, transitioning to cloud computing might be your next move, where you'll leverage Java to develop scalable applications on platforms like AWS, Google Cloud, or Azure.

โ€ข Microservices Architecture: If youโ€™re passionate about designing flexible, modular systems, exploring microservices architecture could be a great fit, where youโ€™ll break down large applications into smaller, independent services using Java.

โ€ข DevOps: If you enjoy automating and streamlining the development process, specializing in DevOps might be the path for you. Youโ€™ll integrate Java applications into CI/CD pipelines and manage their deployment and monitoring.

Even if you choose to stick with general Java development, thereโ€™s always something new to learn, especially with the continuous updates to the language and ecosystem.

The key is to keep coding, experimenting, and staying up-to-date with industry trends. Each step you take in Java development opens up new opportunities to build impactful and innovative software solutions.
