Java DSA Course — Crack Coding Interviews & Placements
Data Structures & Algorithms is what separates a candidate who passes the interview from one who doesn't. Master DSA in Java — arrays to graphs, recursion to dynamic thinking — with the exact problem patterns interviewers test, regular practice, and mock interviews that build real confidence.
Quick answer
Modern Age Coders' Java DSA course teaches Data Structures & Algorithms in Java for coding interviews and placements. It covers arrays, strings, linked lists, stacks, queues, hashing, recursion, trees, graphs, sorting & searching, time complexity (Big-O) and the problem-solving patterns interviews test — with regular practice and mock interviews. Classes are live with a mentor who solves and reviews problems with you. Group plans start at ₹1,499/month, and a free demo is available first.

The Syllabus
Everything You Need for Interviews
A complete DSA roadmap in Java — foundations to advanced — built around what interviews actually ask.
Arrays & Strings
Two pointers, sliding window, prefix sums and string manipulation.
Recursion & Backtracking
Thinking recursively, subsets, permutations and classic problems.
Linked Lists
Singly & doubly lists, reversal, cycle detection, merging.
Stacks & Queues
Monotonic stacks, queue patterns and real interview use-cases.
Hashing
HashMap & HashSet patterns for fast lookups and counting.
Trees & BST
Traversals, binary search trees, height & recursion on trees.
Sorting & Searching
Binary search, merge/quick sort and when to use each.
Graphs & Big-O
BFS/DFS, complexity analysis and intro to dynamic programming.
Why This Course
Built for Interview Success
Pattern-based
We teach the recurring patterns behind hundreds of problems, so new questions feel familiar.
Mock interviews
Practise solving and explaining under time pressure, with honest feedback to improve.
Regular practice
Curated problem sets between classes build the muscle memory interviews demand.
Complexity thinking
Learn to reason about time & space (Big-O) — what interviewers really probe.
Recorded sessions
Every live class is recorded, so you can revisit a tricky algorithm before an interview.
Free demo, fair price
Try a full DSA demo before paying. Group plans from ₹1,499/month.

Why Java for DSA
Why Java Is a Strong Choice for DSA & Interviews
Coding interviews are largely DSA interviews — and Java is one of the most accepted languages for them. Most companies and online judges (like LeetCode and HackerRank) support Java, and its rich Collections framework (ArrayList, HashMap, PriorityQueue, etc.) makes implementing data structures clean and readable. Its strong typing also forces the clear thinking that interviewers reward.
Patterns beat memorising
There are thousands of DSA problems but only a few dozen recurring patterns. We teach those patterns — two pointers, sliding window, fast-and-slow, BFS/DFS, recursion templates — so a new question feels like one you've seen. Combined with hands-on coding and complexity analysis, you stop guessing and start solving.
For students and professionals
Whether you're a final-year student targeting placements or a working professional preparing to switch companies, this course meets you where you are. You should be comfortable with Core Java and OOP first — if not, our adult Java track gets you there. See the full path on the Java classes hub.

Learner Voices
What DSA Learners Say
"The pattern approach changed everything. I stopped fearing new problems because they mapped to patterns I'd practised. Mocks made interviews feel normal."
"Trees and graphs always confused me until the mentor walked through them live in Java. Now I can actually explain my approach out loud."
"As a working dev preparing to switch, the weekend DSA batch and mock interviews were exactly the structured push I needed."

Frequently Asked Questions
The course covers arrays, strings, linked lists, stacks, queues, hashing, recursion, trees, graphs, sorting and searching algorithms, time and space complexity (Big-O), and the common problem-solving patterns asked in coding interviews — all implemented in Java with regular practice.
Yes. Java is one of the most widely accepted languages in coding interviews and on platforms like LeetCode, and its strong typing and rich Collections framework make data structures clear to learn. Many product and service companies accept or prefer Java for DSA rounds.
Yes. The course is built around interview readiness — you learn the patterns interviewers test, practise problems regularly, and do mock interviews with feedback so you're confident solving and explaining solutions under time pressure.
You should be comfortable with Core Java basics and Object-Oriented Programming first. If you're new, we'll start you on Core Java and OOP and then move into DSA — the free demo helps us place you at the right level.
Group classes start at ₹1,499 per month for 2 classes a week. A Mini Batch of 3–4 learners is ₹2,499 per month, and personalised 1-on-1 mentoring is ₹4,999 per month. A free demo class is available before you enrol.
Yes. Every class is live with a mentor who solves and reviews problems with you, sets practice between sessions, and conducts mock interviews. Sessions are recorded for revision.
