Java still runs the enterprise, and Mumbai hires for it constantly. This covers the language, the object model, collections and the JDBC basics that job descriptions ask for.

Arrays
Strings
Methods
You can write and trace any procedural Java code.

Object methods
You can model a domain in classes and justify every access modifier.
The collections hierarchy
Lists
Sets and Maps
Generics
Comparison and sorting
You can choose the right collection and write generic code that compiles cleanly.
The exception hierarchy

Custom exceptions
Resources
You can design an exception strategy and never leak a resource.
Lambdas
The function package
Streams
Collecting
Optional
You can express a data transformation as a stream pipeline.
Streams and readers
The NIO path API
Working with formats
Serialisation
You can process files of any size without loading them into memory.
Threads
Synchronisation
Executors
Concurrent collections
Modern concurrency
You can run work in parallel safely and explain what could go wrong.
JDBC fundamentals
Querying safely
Transactions
Connection pooling
Mapping to objects
You can write parameterised queries and manage connections correctly.
Maven
Unit testing
Code quality
Interview preparation
You can build with Maven, test with JUnit, and explain your code in an interview.
5 builds you keep
Streams a large export, validates each row, batches the inserts, and writes a rejects file with line numbers. The unglamorous job that exists in every company and that nobody teaches.
Calls a real public API, retries only the failures worth retrying, backs off exponentially, and gives up cleanly. The wrapper every service has around its outbound calls.
A blocking queue feeding a thread pool, with a shutdown that finishes in-flight work rather than dropping it. Demonstrates the executor model and the graceful-shutdown problem together.
JDBC, a connection pool, and a stock-reservation flow that has to be correct when two people order the last unit at the same time. Where isolation levels stop being theory.
Reads from MySQL, aggregates with streams, writes a formatted report, and ships with JUnit tests over the calculation logic. Built with Maven, runnable from one command.
Hands on with
Before you enrol
In Mumbai specifically, yes. Banking, insurance, consulting and the large services companies run on Java, and those are the employers hiring in volume here. It is also the language most enterprise interviews are conducted in.
We teach a current LTS release and point out what changed after Java 8, because plenty of existing code is still on 8. Knowing records, streams, var and switch expressions is what separates a fresh candidate from a dated one.
Not in this course. This is the language, the object model, collections and JDBC done properly, which is what Spring assumes you already know. Going into a framework without that foundation is why people get stuck the moment something breaks.
It is more verbose and the compiler asks more of you up front. That strictness is the reason large teams use it, and static types make a big codebase navigable in a way a dynamic language does not.
This is the core that every Java role assumes. Most junior postings also want a framework and some SQL, so the usual next steps are our SQL course and then Spring on your own, which is far easier once the language is solid.
Where this leads
One skill on a CV is a hobby. These are the courses students take alongside this one, in the order that builds an actual role.
Every serious technical interview is a data structures interview. You build each structure by hand in C and C++, then drill the patterns that recur across company assessments.
The shortest route from no code at all to a working, employable skill. Sixty hours of live teaching that starts at absolute beginner and ends with five projects and a deployed web application in your portfolio.
The theory and the practice together. ER modelling and normalisation for your university paper, and real SQL against real schemas for the job.
