Mini projects are an important starter kit for developers who want to pursue a career in tech.

Interviewers are particularly interested in your mini projects. The computer science mini projects you work on sheds light on your career interests and speaks for your enthusiasm to learn tech concepts at a deeper level.

Moreover, when you apply your theoretical knowledge in a hands-on way, you get to explore a breadth of concepts related to your topic.

The practical experience gained from tackling technical challenges in your mini project helps you walk away with longer retention of applied skills.

How to choose mini projects

When it comes to selecting a mini project, it is not paramount to select an innovative idea. What you learn out of it is important to showcase your skillset.

More than going after the number of projects, interviewers usually ask questions hoping you would have chosen mini projects that you care about. Having multiple projects in your resume and not being able to give in-depth answers about them throws you in a bad light.

Best strategy to choose the right projects

As a recommended practice, work towards having 3-5 mini projects in your resume.

Check out some interesting projects you can add to your resume.

Use the following checklist to choose your mini projects:

  1. Select mini projects that add value to your career goals.
  2. Make sure they are in line with your programming interests.
  3. Build or add a feature that solves a real problem.

Some questions to think about when choosing innovative project ideas:

  1. What problem is my project solving?
  2. Who is it solving for?
  3. Why does this problem need to be solved?
  4. Are the skills and technologies relevant today/next 5-10 years?

Always keep these points in mind when choosing project ideas for computer engineering.


How to include projects in your resume

It doesn’t stop at just working on multiple mini projects. An important element in getting noticed by leading tech companies is to present your skills in an informative and engaging way.

Also read: Learn how to write appealing work descriptions in your resume.

Before adding all projects in your resume, take a moment to structure your information in a concise and consistent manner. Include information that would interest your potential employer.

When scanning through your resume, in one glance they should understand:

  1. What your project is about
  2. What you did in the project
  3. The skills and technologies you have used in the project
  4. Time spent on the project

Later when you are called for an interview, be prepared to answer questions related to:

  1. The thought process behind selecting the mini project
  2. Technical challenges faced during the mini project
  3. How you overcame them
  4. Anything you would do differently to improve your project today
  5. Key learning outcomes from the mini project

Java projects

Breakout Ball Game

Java projects - breakout ball game

Java is widely used by game development companies and for creating mobile games. And this fact shouldn’t come as much of a surprise, given how versatile the language is and given its rich collection of open-source material.

Many of the world’s top mobile games have been developed in Java. Minecraft, Mission Impossible III, and Asphalt 6 are just a few popular names you are probably familiar with.

In this project, a layer of bricks lines the top third of the screen and the goal is to destroy them all. A ball moves straight around the screen, bouncing off the top and two sides of the screen. When a brick is hit, the ball bounces back and the brick is destroyed. The player loses a turn when the ball touches the bottom of the screen; to prevent this from happening, the player has a horizontally movable paddle to bounce the ball upward, keeping it in play. The player uses the platform to keep the ball running. The goal is to break the bricks without missing the ball with your platform.

Skills to hone

By end of the project, apart from learning to write clean modular code using Java you will also learn some major concepts such as -

  • Java Swing - Swing in Java is a lightweight GUI toolkit which has a wide variety of widgets for building optimized window based applications. It is built on top of the AWT API.
  • Java AWT - The Abstract Window Toolkit (AWT) is Java's original platform-dependent windowing, graphics, and user-interface widget toolkit, preceding Swing.
  • JFrame - A frame, implemented as an instance of the JFrame class, is a window that has decorations such as a border, a title, and supports button components that close or iconify the window.
  • JPanel - The JPanel is the simplest container class. It provides space in which an application can attach any other component. It inherits the JComponents class.

The project makes use of Java swing, OOPS concepts and much more. All in all you will be experiencing how it is to develop graphics-intensive applications using native languages like Java.

These skills will aid in the future when you pursue domains like mobile application development, web-based apps in conjunction with Flash.

Learning these will be an additional support and a star point when you collaborate with a different tech stack to build games or graphical animations.

These are hot skills that the industry happily accepts, so it is a strong pointer for your résumé!  

Excited to try this project?

Who should try this

  • Prerequisite knowledge required

Library Management System

Java projects - library management system

Management systems are used in all institutions. It may be digital (software) or analog (record books/ledgers), but everybody surely uses it.

Today data is power.

But having said so this data should also be well-managed for clean and accurate data to exist at all times.

One such system is the Library Management System, which is used to keep a record of books present in a library. This system consists of information regarding Books, where we can perform all the operations that are required in an actual system such as CRUD operation, advanced search, book issuing, and also to store the information (in an encrypted format) within files using the process known as Serialization.


By end of the project, apart from learning to write clean modular code using Java and OOPs concepts, you will also learn some major concepts such as -

  • Serialisation - Serialization in Java is a mechanism of writing the state of an object into a byte-stream (to store the book data here). It is mainly used in Hibernate, RMI, JPA, EJB and JMS technologies. The reverse operation of serialization is called deserialization where a byte-stream is converted into an object (to access the book data from stored files).
  • Java Collections API - This provides Java developers with a set of classes and interfaces that makes it easier to work with collections of objects, e.g. lists, maps, stacks etc. Rather than having to write your own collection classes, Java provides these ready-to-use collection classes for you.

This project will empower you to build management apps which are super popular these days.

These skills will aid in the future when you pursue domains like app-web development, system design, domains like project management apps such as Trello, slideshare.

Learning these will be an additional support and a star point when you collaborate with a different tech stack to build robust apps that include concepts like serialisation and may also employ your knowledge of classes, objects usage that you can strengthen from this project.

This project can right away go on your résumé!

Who should try this

A basic knowledge of Java concepts will be required to execute this project. Having knowledge of OOPs concepts will help greatly. But these can surely be learned through the course of implementing this project.
