Why should I learn Data Structure and Algorithms with Java?
  • Data structures in Java are organized linearly, one on the other, hierarchical fashion and through connecting nodes.
  • Data structures used in Java are array, linked list, stack, queue, binary tree, binary search tree, heap, hashing, and graph.
  • The Java collections framework includes several techniques for manipulating components contained in data structures. In Java, algorithms are static methods used to execute various actions on collections. Algorithms are sometimes referred to as generic algorithms.
  • Algorithms applied in Java are sorting (quick, merge, bubble, selection, and insertion), shuffling, searching, routine data manipulation, composition, and finding extreme value.

Who can Enroll


  •   Students in pre-final/final year looking for good placements.

My name is Shikha Singh and I am a professional coding teacher with over 6 years of experience.

I hold a B.E. degree and have a strong passion for helping others learn and grow in the field of computer science. Throughout my career, I have had the opportunity to teach a variety of programming languages including Python, C++ , javascript and more One of my greatest joys as a teacher has been the opportunity to work with over 500+ students, helping them to achieve their goals and succeed in their studies. I am dedicated to providing high-quality, personalized instruction to each and every one of my students.


I am Jyotika Negi , Full stack web development instructor at Dhruvon.

I have been teaching web development with HTML, CSS, Javascript for more than 2 year now . I have been conducting webinars and introductory sessions on web development for more than 3 years, also participated in various Hackathons and worked on various web applications and websites that includes movie recommendation system, tiktok ,Instagram clone etc. At Dhruvon, I am just combining my two passions that is coding and teaching


My experience with Dhruvon was remarkable, everything I learnt was easy to comprehend and it was explained in a very elaborate but brief manner, it was a very easy method to understand such a hard course as it would have taken me months to understand it from someone else. Wherever I had a doubt it was cleared in only a few minutes with proper feedback too.

Gaurav Punjabi

I would highly recommend this course to anyone who is looking to gain some knowledge with Python. Dhruv Sharma (course instructor) is the man! He explains things really well and shows great examples throughout his explanation. Again I highly recommend it.

Akshat Kaushik

My Son surprised me with his coding skills & the credit goes to Dhruvon for making his learning so simple yet informative. Dhruvon teaches in Hindi. I believe that's their USP

How do you choose between Data Structures and algorithms (Java) /Data Structures and algorithms (C++) /Data Structures and Algorithms (Python)?

Data Structures and algorithms (Java)
Java is a must-know programming language if you want to develop Android mobile, desktop applications, or server backends. Also, use Java if you need to write large amounts of code as Java is comprehensive, understandable, and well-structured
Data Structures and algorithms (C++)
If you are working with a domain model which is complex and needs object-oriented programming, then you need to know C++. Other than this, if you are involved in video gaming, graphics and computer vision, and web browsers (Chrome, Firefox, Safari), C++ is the programming language that you need.
Data Structures and Algorithms (Python)
If you are venturing into the field of machine learning, deep learning, and artificial intelligence, Python is your go-to programming language. It is helpful in visualization and data analysis. Python is also useful for web development with frameworks like Django. In comparison to many other languages, Python has a very simple syntax
