Java is a general-purpose, object-oriented programming language developed in the mid-90s by James Gosling in Sun Microsystems. It floors WORA (Write Once, Run Anywhere) i.e. the Java code needs to be compiled only once then it can be executed in any of the systems that support Java without any need of recompilation.
But the obvious question arises, why should one choose Java among various programming languages? This is because of the key features of Java. Some of those are:
- Simple
- Object-Oriented
- Platform Independent
- Robust
- Secure
Java finds its application in almost every domain like software tools, android applications, web development, scientific/research applications.
To get in-depth knowledge of concepts of Java, one can build some Java projects that will help them understand Java efficiently, and one can showcase the project in their resume.
Java projects for Beginners
1. Password Generator using Java
With the increasing number of hacking attacks, everyone should use different and complex passwords for their different accounts to be secure. Since humans can’t remember every password and also writing it somewhere in a notebook or diary is not a good idea, people use password generators to generate strong and complex passwords for their online accounts. A good idea for Java projects for beginners would be a password generator.
To create such functionality by yourself, you can take advantage of the random function that Java provides. Whenever a user is creating an account on a new website, he/she can run that program to generate a password and store it in a file that is secured with a super password already.
To take the security of the password a step above, you can implement such functionality that it stores passwords in encrypted form. For this, you need to explore the basics of Cryptography and Java Cryptography Architecture.
2. Online Banking Interface
This is one of many interesting Java projects for beginners. The main idea of this project is to develop a net banking system that can be accessed from any location with any device by the user, he/she can perform a variety of operations like money transfer, balance inquiry, printing e-statement, etc.
The need to develop such an application is to be able to avoid going to physical branches of a bank, standing in long queues, and most importantly saving time.
The application should have these features:
- Users can perform general operations like viewing balance, transferring money, viewing debit/credit statements, etc.
- Users can generate bank statement/transaction history of a time range either monthly or custom range provided by the user.
- It should show various loan offers available, the interest rates on them, other benefits, etc.
3. Online Survey System
Another good Java project idea is to develop a core Java project that can collect the viewpoint of a targeted audience of a survey via the Internet. The application can send promotional emails and can launch online surveys.
Any enterprise can use this type of software to gather feedback about their services or product. You can create such functionality so that only registered users can cast their responses.
Maine features of the application should be:
- Programmed in such a way that it should be compatible with different databases (SQL or NoSQL).
- Users can submit their responses anonymously.
- Should be installed at a feasible cost.
4. Inventory Management System
This is one of the best Java projects for beginners. A web-based or native application that can manage an organization’s inventory and handle sales and purchases of different items. It will consist of different modules for adding, removing, purchasing, viewing items from the database.
The application consists of a login page from which administrators can log in using a valid id and password and can perform these operations:
- Adding an item.
- Removing an item.
- Viewing item details.
- Combining two or more items into a single product.
And many more like printing daily/weekly reports, payment receipts, etc.
5. Electricity Billing System
This Java project is a modern version of the traditional electricity billing system where a person collects information from our electricity meter. The main goal of this project is to automate the whole process to make it seamless, accessible, and efficient.
The software can calculate the bill amount based on units of electricity consumed within a month. This is one of the top Java project ideas for beginners.
The application should have the following features:
- Accurately measure the bill amount.
- Instant data sharing between local electricity offices and customers.
- Highly secure to nullify the chances of tampering.
6. Online Resume Builder
People find it difficult to create their resumes. The idea of this Java project is to make this process seamless for the user. it simplifies the task of creating a CV or resume for an individual.
You can select some good-looking and industry-accepted resume templates, and ask the user to enter the details he wants to add to the resume. After entering all the required information, a customized resume can be generated in .pdf and .doc format by clicking on a single button.
The application should have the following features:
- Attractive resume template.
- Update every piece of information according to the user’s needs.
- Should have the functionality to print the resume directly.
7. PDF Converter
This Java project can convert a .doc file or any other text file into a PDF. It is a simple but quite useful core Java project. Many classes are there in Java to implement functionality instead of writing long codes.
This project looks simple, but you will get to learn some core Java concepts, file handling, and inbuilt packages of Java by doing it. The application should have the following functionalities:
- Can convert all major file types(.doc,.docx, .ppt, .tex, etc.) to PDF
- Can print the pdf from there itself
- Text in the final PDF should be properly indented as per the source file
8. Snake Game using Java
Almost all of us have played classic snake games in our childhood. Now we will try to implement it using Java concepts. The idea seems to be simple but it's not that easy to implement.
One needs to understand the OOPs concept in depth to implement this efficiently. Also, concepts of Java Swing are used to develop this application.
The application should have the following functionalities:
- The Snake can move in all four directions.
- The length of the snake increases as it eats food.
- When it crosses itself or hits the boundary of the box, the game gets over.
- Food is generated at random positions always.
9. Text to Speech using Java
This Java project is to help specially-abled people who can’t read. To help them you can create an application that can generate spoken language from a text file saved on the system.
With Java Speech API it is possible because it allows speech synthesis (a process of generating spoken language based on text input). While doing this project you will get a chance to learn the OOPs concept and Java Speech API in depth.
The application should have the following functionalities:
- Can read text from other file types also like .pdf or .doc.
- UI should be user-friendly.
- Option to select different voices.
10. Tesseract OCR using Java
OCR is an optical character reader, which can read text written on an image. Java offers such functionality using Tesseract which was developed by HP Laboratories that can read more than 100 languages out of the box.
This project is a bit more difficult to implement than others but the things you get to learn while doing it will be worth it.
The application should have the following functionalities:
- It should pre-process images.
- Should have a module to detect unclear images.
- It can save the extracted text from the image into a file.
- Should support all the popular image types like (.jpg, .jpeg, .png, etc).
Wrapping Up:
There are plenty of project ideas that one can implement using Java. In this article, we have covered some amazing Java project ideas for beginners, be it students or professionals, who are beginning their journey with Java.
Start with the basic projects, then slowly move toward complex projects as you gain expertise in Java because working on different projects is the only way you can understand how things work in real life, what are the challenges that come across while developing an application, how to counter those challenges, etc.
