The work

An API that only works on the happy path is not finished

Getting an endpoint to return JSON is the easy part. Rejecting bad input with a clear error, keeping queries fast, locking it down with roles and proving it with tests. That is the internship.

  • 1You get a realistic fictional client, such as a courier company, a clinic or a car rental firm
  • 2You build in small steps and push each one to a public GitHub repository
  • 3Your mentor reviews every task against written criteria, tests included
  • 4You hand over a backend that starts with one command and a README a new team can follow

Java basics and Git are covered in weeks 1 to 2. You do not need Java experience, only a laptop and the will to practise most days.

booking/BookingController.java
// Week 6: bookings API for a fictional car rental company
@RestController
@RequestMapping("/bookings")
public class BookingController {
    private final BookingService service;
    @PostMapping
    public ResponseEntity<BookingDto> create(@Valid @RequestBody NewBooking req) {
        BookingDto saved = service.create(req);
        return ResponseEntity.status(HttpStatus.CREATED).body(saved);
    }
    @GetMapping("/{id}")
    public BookingDto get(@PathVariable long id) {
        return service.find(id);  // unknown id becomes a 404 ProblemDetail
    }
}
// proof: curl calls and their responses pasted in README.md
Skills

What you will be able to do after this Java internship

01

Core Java

Variables, types, loops, methods, classes, records and enums in Java 21.

02

Collections and exceptions

Lists, maps, generics and custom exceptions, so a bad line in a file gets a message, not a crash.

03

Modern Java

Streams, lambdas, Collectors, Optional and java.time for reports people can read.

04

Spring Boot REST APIs

Controllers, services, dependency injection, DTOs as records and the right HTTP status codes.

05

Spring Data JPA

Entities, repositories, relationships, pagination and spotting the N+1 problem.

06

Databases and migrations

SQL, H2 for development, PostgreSQL in Docker and Flyway migrations.

07

Security and validation

Bean Validation, ProblemDetail errors, and Spring Security with JWT login, BCrypt and roles.

08

Testing and delivery

JUnit 5, Mockito and MockMvc tests, OpenAPI docs, Docker Compose and a GitHub Actions pipeline.

Curriculum

The Java internship plan, 3-month version

Four phases. Each one ends in a deliverable that is reviewed and graded before the next opens.

Java foundations

From your first program to clean, tested classes.

  • Install the JDK, IntelliJ IDEA Community and Git
  • Variables, types, conditions, loops and methods
  • Classes, records, enums, lists and maps
  • Exceptions, generics and your first JUnit 5 tests
Deliverable

A console tool for a fictional courier company that reads a file of parcels, handles bad lines and passes its tests.

The capstone

Every intern hands over a backend another team could pick up on Monday

You bring a Spring Boot API for a fictional client together into one consistent backend, with JPA, validation, JWT login and roles, tests, OpenAPI docs and Docker Compose, and hand it over with a README, a decisions log and a changelog.

  • Every endpoint in a table with the role that may call it
  • The full test run and a green CI run pasted as text
  • One command to start it, and the decisions behind it written down

The Ezitech model

What the Java internship includes

Three things that make this different from a course you watch on a screen.

Client-style projects

You work on projects written for realistic client companies, with deadlines and revision rounds, not recycled practice exercises.

A mentor, not a playlist

Every piece of work is reviewed against written criteria, you can ask your mentor at any time, and other interns are around you to build with.

Portfolio and verified certificate

You finish with work you are allowed to show and a QR-verified certificate that states your track and dates.

And you leave with

  • Verified certificate

    Issued by Ezitech Institute and verifiable by employers.

  • Verified certificate

    A QR code lets anyone confirm your track and dates online.

  • A tested Spring Boot API

    A secure, documented backend that runs with Docker Compose, plus four console programs on GitHub.

  • Interview preparation

    CV rewrite, portfolio case study and a technical mock interview.

  • A portfolio you can show

    Every accepted task appears on your public Ezitech profile, under the project it belongs to.

  • Confidence in review

    Month after month of explaining and defending your own work in reviews.

Built for you if

  • You are a student or fresh graduate in CS, IT or software engineering
  • You want to build the backend logic that apps depend on
  • You want to become a Java, Spring Boot or backend developer
  • You need an internship or a final-year project with a real API on GitHub

Not a fit if

  • You want a certificate without doing the work
  • You cannot work on it most days for the months you choose
  • You only want to build Android apps or front-end pages
  • You want to skip review and work alone

Contact Ezitech

What does a Java intern do at Ezitech?
A Java intern at Ezitech writes console programs first, then builds a Spring Boot REST API with a database, validation, security and tests for a realistic fictional client, with a mentor reviewing every task. Each step goes to a public GitHub repository with a README that shows the test output and example calls.

Do I need Java experience for the Java internship?
No, you do not need Java experience: the track starts with installing the JDK and writing your first console program. Basic computer skills and the will to practise most days are enough, and any earlier programming makes the first weeks faster.

Does the Java internship teach Spring Boot?
Yes, Spring Boot is the core of the internship from the second phase onward: REST controllers, Spring Data JPA, Bean Validation, Spring Security with JWT, tests with JUnit 5, Mockito and MockMvc, and OpenAPI docs. The first weeks are plain Java, so you understand what Spring does for you.

Should I choose the Java or the .NET internship?
Choose this Java internship if you want Java and Spring Boot, and choose the .NET internship if you want C# and ASP.NET Core; both build the same kind of secure, tested backend API. If you want front end and back end together, see the full stack development internship.

Which tools does the Java internship use, and are they free?
Yes, every tool is free: the JDK from Eclipse Temurin, IntelliJ IDEA Community or VS Code, Maven or Gradle, H2, PostgreSQL in Docker, and curl or the free Postman. You never need a paid IDE, a paid host or a credit card.

Can I do the Java internship remotely?
Yes, you can do the Java internship fully remotely from anywhere in Pakistan, or onsite at the Ezitech office in Rawalpindi. You choose 1 to 6 months, hybrid (onsite in Rawalpindi or remote), and your mentor reviews the same code in both modes.

Is there a fee, and is the internship paid?
There is a one-time programme fee and there is no stipend. You start with a 7-day trial before paying anything, and the full fee and refund rules are on the internship fee and refund policy page.

Does the Java internship guarantee a job?
No, there is no job guarantee with the Java internship or any other Ezitech internship. You finish with a tested Spring Boot backend and four console programs on GitHub, a mock interview and help with your CV and LinkedIn for roles such as junior Java developer, associate software engineer and backend developer (entry level).

Who runs this internship?
Ezitech Software House runs it: a software house in Rawalpindi, Pakistan, founded in 2015 and registered with the Pakistan Software Export Board (PSEB). Ezitech Software House and Ezitech Institute are the same company. “Ezitech Institute” is the name used for its internships and training. The office is at Office #304-B, Amna Plaza, Main Peshawar Road, Rawalpindi, Punjab 46000, Pakistan.

How do I apply for the Java internship?
Press Apply now on this page, register on the Ezitech intern portal with your basic details and choose Java Development as your field. No CV or work experience is needed, you start with a 7-day trial with no payment, and you can start any day.
