Begin your career in software development with the introduction to Data Structures and Algorithms in Java. Java, an Object Oriented Programming is one of the most sought after programming language and is the foundation of the Android operating system. Java is a perfect computer language for being competitive in today’s industry requirements.Designed for beginners, our online java course is a hands on course where we focus on developing core programming concepts and equip you to code solutions for complex problems using Java.

More than 200 recorded videos and 6 live webinars, along with 24x7 doubt clearing support. Course starting June 4.

We have designed our course keeping in mind the requirements of beginners. Course starts with fundamentals of logic building and problem solving. Many tricky Puzzles are also given to build logical thinking of our students.

Problem Solving

The course is designed to sharpen the problem solving skills of the students. We follow step-by-step approach to make students fall in love with programming and ignite their passion of coding with the help of problems ranging to easy to intermediate to expert level.

OOP Concepts & Project

Emphasis is given on building strong Object Oriented Programming Concepts and coding practices followed in the Software Industry, so to make our students industry-ready. Students will also build a game with Java Swing Libraries to strengthen their OOPS concepts.

Data Structures 
& Algorithms

This course entails more than 100 hours of teaching and hands on coding. Students will be solving more than 200 complex problems and will be evaluated for their problem solving skills and understanding of data structures throughout the course.

Course Contents

Logic Building and Java Fundamentals

Course will start with basic understanding of logic. We will be discussing about Flowcharts, PsudoCode and students will solve also some of the Puzzles in initial classes.

  • Flowcharts, pseudo-code and brain teasers
  • IDE installation and familiarization
  • Debugging
  • Input-Output
  • Data Types and Variables
  • Typecasting
  • Loops and Decision constructs
  • Functions and operators
  • Arrays, multi-dimensional arrays and dynamic arrays
  • String and String Buffer


Then we will dive deep into Recursion and solve complex problems involving backtracking.

  • Introduction
  • Classical Recursion Problems
  • Back-tracking
  • Advanced Recursion problems
  • Optimization


In this part we learn about how to compute space-time complexity of our solution and how can we optimise our solutions. We will also learn about OOPs and recommended coding practices.

  • Classes and objects
  • Class, Function and Data member modifiers
  • Encapsulation, Inheritance and Polymorphism
  • Abstract classes, Interfaces and Packages
  • Generics and Exceptions

Data Structures and Algorithms

Lecture 14-23

This is the most important and exciting part and yet easy. Data structures are all about storing data.You will learn to implement different data structures and when to use them. This part is important as most of the questions asked in interviwes are related to data structures.

  • Linked Lists
  • Stacks
  • Queues
  • Generic Trees
  • Binary Trees
  • Binary Search Trees
  • Hash Tables & Heaps
  • Graphs – Traversals, Minimum Spanning trees, Shortest path algorithms
  • Text Processing – Text Matching, Compression
  • Dynamic Programming

Project Development

Project Development

In last classes we will build a game using Java Swing Libraries.

  • Learning about Java Swing
  • One game developed in class
  • Second game done as assignment
Regular Batch

  • Who should do this course?

    Anybody who is interested in learning programming can take the Java training. Java is a powerful and elegant language, but still is pretty easy to learn. Also, this opens the path to enter Enterprise Java world for making powerful desktop and web applications or mobile apps using Android.

  • I know C, should I do this course?

    Yes. Absolutely. Not only will this course teach you Java, but also Object Oriented Programming which forms the base of most, if not all code running live across the globe. Besides it builds your problem solving skills, teaches you some fine data structures and helps you develop the thinking process to optimise your solutions.

  • I know C++, should I do this course?

    Depends. Knowing C++ generally means you know Object Oriented Programming well. If that is the case, you’ll be better served by learning some courses which teach you to create making mobile apps or web applications. Please check out our Pandora and Elixir course for those.

  • Will this help me with competitive programming or can I apply to ACM-ICPC after doing this course?

    This course will help you become smarter with your solutions. You’ll be able to write solutions that run in lesser space and time. The last time we heard from capable competitive programmers, they said these skills made them capable.

  • Will this course help me in Interviews?

    Yes. If you learn well, all that the course intends to teach, you’ll be able to impress quite a few interviewers across quite a few fine companies.

  • Will this help me in making websites and apps?

    No. This is a fundamentals course. To make websites and apps, you need to learn more. Please check out our Pandora & Elixir course for those.

  • Is this CORE Java or Advanced Java?

    This is not CORE java or Advanced Java. This is a course which teaches you problem solving, data structures and Object Oriented Programming. Though, most of what CORE java means is being covered. The aim of the course is to help you with a smarter beginning. For being able to make web and mobile apps you need to learn frameworks. Android is one such framework for mobile apps. Please check out our Pandora and Elixir course for more details on these lines.

    Coding Blocks was an amazing experience for me. I belong to the electronics department and had a little experience in coding but I think it has helped me think things through in a much more analytical manner. Coding is important no matter which branch you are in. It gives you a better understanding about how to approach a problem.

    ★ ★ ★ ★ ★

    It was an amazing experience! i got no words to explain the emotions of satisfaction, joy and happiness i achieved after completing this course. sir is such an amazing person, and i am completely positive that he was one of the best teacher who ever taught me. A young man with complete knowledge of his subject, along with a great experience in both the job line and teaching.

    ★ ★ ★ ★ ★

    it really turned out to be lucky for me because the experience was amazing and it really helped me generate an everlasting love for coding. We were taught by Piyush Ajmani sir who was further backed by two TA’S (Pranav and Abhishek sir). The way of teaching was quite systematic and they left no stone unturned in instilling very complex concepts in a very clinical way.
