PROGRAMMING & DATA STRUCTURES
Understand the problem.
Build a clear Java solution.
Build programming fundamentals, master data structures and turn interview problems into clear, efficient solutions using Java.
Recognise reusable patterns
Work through arrays, recursion, trees, graphs and dynamic programming with a structured approach.
Explain your reasoning
Practise correctness, edge cases and complexity so your explanation is as strong as your code.
Your skills matter in the AI era.
In the AI era, Java and logical thinking remain essential. Use your DSA foundations to review generated code, check edge cases and reason about time and space complexity.
A ROADMAP THAT BUILDS ON ITSELF
From your first method
to confident problem solving.
Build Java foundations, implement core structures and practise the algorithms that connect them.

BEFORE YOU START
A little clarity.
A confident next step.
Need help with your starting point or schedule?
Talk to an advisorWhat should I know before joining?
You can start with the Java programming foundations module. It introduces methods, classes, objects and collections before moving into DSA. If you already code, use the course to strengthen your problem-solving patterns.
What will I practise and build?
The roadmap covers programming foundations, arrays, strings & complexity, recursion & backtracking, core data structures, trees & graphs, dynamic programming & interviews. Project ideas include Route planner, Data structure toolkit. Ask your advisor to confirm the work and review process for your selected batch.
How does AI fit into this course?
In the AI era, Java and logical thinking remain essential. Use your DSA foundations to review generated code, check edge cases and reason about time and space complexity.
How do I choose a centre and schedule?
Use the NSP and Noida selector to compare any published weekday and weekend schedules. If a centre has no listed batch, our team can help you check upcoming availability. Ask about live online options if you prefer to learn remotely.
What are the fees, duration and mentor details?
These depend on your selected batch. Review the available schedule and fee together, and ask our team to confirm the current duration, mentor allocation and enrolment details.
How do I download the syllabus?
