Java is a general-purpose, object-oriented programming language created by James Gosling at Sun Microsystems in the mid-1990s. It implements WORA (Write Once, Run Anywhere), which means that java code only needs to be compiled once and can then be run on any system that supports java without the need for recompilation.

However, the obvious issue arises as to why one should choose Java over other programming languages. This is due to several of Java’s core features, which include:

  • Platform Independent
  • Robust
  • Secure
  • Simple Object-Oriented

Java is used in practically every industry, including software development, Android applications, web development, and scientific/research applications.

To gain a thorough understanding of Java principles, one can create Java projects that will aid in our understanding of the language and can be included in one’s résumé.

1. Java-based password generator


With the rise in hacking assaults, everyone should use unique and difficult passwords for each of their accounts to stay safe. Because humans are incapable of remembering every password, writing it down in a notepad or journal is not a smart idea.

People use password generators to create secure and complex passwords for their online accounts for this reason. To construct similar functionality on your own, you can use the random function provided by Java.
Whenever a user creates an account on a new website, that program can be used to generate a password and save it in a file that is already protected with a super password.

You can add such capability to store passwords in encrypted form to take password security a step further. You’ll need to learn the fundamentals of cryptography and the Java Cryptography Architecture to do so.

2. User Interface for Online Banking

Man using online banking with credit card on touch screen device. Mobile banking. Digital and internet payments shopping on network connection. Bank login on a laptop screen. All on screen and credit card are design up.

This is a fun Java project for beginners to work on. The major goal of this project is to create a net banking system that can be accessed by the user from any location and on any device, allowing him or her to do a variety of tasks such as money transfers, balance inquiries, and e-statement printing.

The demand for such an application arose from the need to avoid visiting real bank branches, standing in long lines, and, most significantly, saving time.

The following functionalities should be included in the application:

Users can view balances, transfer money, and view debit/credit statements, among other things.
Can generate a bank statement/transaction history for a time period specified by the user, either monthly or on a custom basis.
It should display the many loan options accessible, their interest rates, and their perks, among other things.

3. System for conducting online surveys


The goal of this project is to create a core Java project that can use the Internet to gather feedback from a targeted audience for a survey. The application has the ability to send promotional emails as well as conduct online surveys.

This type of software can be used by any company to collect feedback on their services or products. We can implement this capability so that only registered users can vote.

The following should be included in the application:

It is programmed in such a way that it should work with a variety of databases (SQL or NoSQL).
Users have the option of submitting their replies anonymously.
It should be installed for a reasonable price.

4. Inventory Control Software


This is a web-based or native application that can manage an organization’s inventory and handle sales and purchases of various commodities, and it’s one of the greatest Java projects for beginners. It will have many modules for adding, removing, purchasing, and viewing database items.

The application has a login page where administrators can log in with a valid id and password and conduct the following tasks:

I’m going to add something.
Taking anything out of the picture.
Viewing the specifics of an item.
Creating a single product by combining two or more items.
There are many others, such as printing daily/weekly reports and payment receipts.

5. Billing System for Electricity


This Java project is a modern take on the conventional power billing system, in which a person gathers data from our meter. The project’s major purpose is to automate the entire process in order to make it more seamless, accessible, and efficient.

The bill amount can be calculated using the number of units of electricity consumed over the course of a month. This is one of the best beginner Java project ideas.

The following functionalities should be included in the application:

Calculate the bill amount precisely.
Customers and local electricity agencies can share data instantly.
To eliminate the possibility of tampering, the system is extremely secure.

Wrapping Up

To summarize, there are numerous project concepts that can be implemented utilizing Java. We’ve explored some fantastic Java project ideas for students and professionals that are just getting started with Java in this article.

Start with simple projects and work your way up to more complicated projects as you acquire experience with Java. Working on different projects is the only way to learn how things function in real life, what obstacles you’ll face while designing an application, how to overcome those challenges, and so on.

Now is the time to pick a project and try to create it on your own. If you want to study java and programming, check out Singapore Coding Club’s Java Programming Course, which will teach you the principles of Core and Advanced Java.
