Who this is for

The enterprise workhorse for a Hyderabad hiring market

Java powers the banks, insurers and product companies that dominate Hyderabad's job boards. A Java Full Stack developer is consistently in demand.

Fresh graduates targeting enterprise IT

Java is where the volume of Hyderabad jobs is. If your goal is the widest possible entry door into a software career, this is it.

Self-taught developers going formal

Already know some Python or JS? Rounding out with Java's strict typing, build tooling and testing discipline changes the interviews you can pass.

Career-switchers ready for a long ramp

Java demands more patience than Python. If you want a career that values depth over speed of first build, that patience pays off.

Not the right track if…

You want the gentlest possible first language. Java's ceremony — classes, interfaces, build tools — feels heavy until it clicks. Python Full Stack is the softer start if the learning curve is the blocker.

Curriculum

Twelve modules from first Java syntax to a deployed API

Each module ends in working code you can point to in an interview.

  • Syntax, data types, operators, control flow and arrays
  • Why Java feels more formal than Python, and where that discipline pays off
  • JVM, JDK and the compile-and-run model
  • Classes, objects, inheritance, polymorphism and interfaces
  • Abstract classes, packages and access modifiers
  • Composition over inheritance and when to use each
  • List, Set and Map — when each collection earns its place
  • Functional streams: filter, map, reduce
  • Checked vs unchecked exceptions, and custom exceptions
  • Connecting Java to MySQL and performing CRUD
  • Prepared statements and preventing SQL injection
  • Transactions and connection management done properly
  • Maven lifecycle, POM files and dependency management
  • Standard project structure real teams expect
  • Running and testing the build from the command line
  • The Spring container, beans, scopes and singletons
  • Constructor vs setter injection
  • Profiles, configuration and externalised settings
  • Building REST APIs with @RestController and request/response models
  • Validation and exception handling
  • Actuator endpoints and health checks
  • Entities, repositories and @OneToMany / @ManyToOne relationships
  • Lazy loading, JPQL queries and fetch strategies
  • Transactions and optimistic locking
  • Authentication flows and password hashing
  • Token issuance and validation
  • Role-based access control secured end to end
  • Components, hooks, router and state
  • Consuming the Spring Boot API from the browser
  • Building the storefront end to end
  • Unit tests for services and controllers
  • Mocking dependencies with Mockito
  • Writing tests that give you interview confidence
  • REST clients, a simple gateway and service discovery
  • Docker for the Spring Boot service
  • Deploying the API and React front end
