The Top 12 Java Projects That Will Enhance Your Portfolio

If you are looking to enhance your portfolio with a diverse array of Java projects, then this blog is for you.

Working as a professional Java developer necessitates at least some knowledge of how to write decent Java code. When studying Java, the emphasis is on mastering the fundamental principles. However, it's critical to hone your ability to use those concepts to build Java-based apps that solve a variety of real-world issues.

Working on real-time Java projects is the best method to apply what you've learned. You can create projects of varying difficulty levels to expand your expertise and discover new Java programming topics. Furthermore, the most important advantage of designing Java applications is that you can add them to your portfolio and improve your chances of getting better-paid projects.

Why do Organisations Prefer Java as a Programming Language?

Java is a programming language that is used on an extensive scale. It is a high-level general-purpose, and object-oriented programming language with a wide range of usages. Java is a programming language that may be used to create online apps, mobile applications, games, and desktop GUI programmes.

James Gosling created the Java language in 1995. Today, however, Oracle Corporation is in charge of the Java SE platform's development and maintenance. A feature of the programming language that effectively turns it into a cross-platform programming language is called "WORA." Also, due to WORA, compiled Java code can be executed on any system that is compatible with Java (and the JVM) without recompiling it.

Java was graciously welcomed by the software industry because it made development effortless, eased distribution issues, and eliminated the pain of continuously porting across platforms. The language is dynamic and secure as it is object-oriented. Java programmes are written in the bytecode language, which allows them to run on any machine with a JVM installed. This is a pragmatic and logical approach to software development. Java objects encompass data and behaviour, enabling code to be reused along with streamlining testing and debugging.

When individuals and companies acknowledged how Java could deal with their issues on servers, they adopted it which increased performance, productivity, and scalability to another level. Java has established its dominance over other languages in a variety of areas, including software distribution via the internet, server-side scaling of multi-tier architectures, leveraging ever-expanding hardware architectures, cloud-native deployments, and much more.

The Top 12 Java Projects That Will Enhance Your Portfolio

Data visualisation software

As data visualisation is concerned with the graphical or pictorial representation of data, data visualisation software makes it more efficient and convenient for users to interpret information expressed in charts or graphs rather than report pages. The data visualisation software project will use data visualisation to show node connectivity in networking.

The key objectives of this project should be to explicitly communicate information using graphical and pictorial methods. These are both useful as well as visually pleasing. And they eloquently express essential insights into complex collections of data and information, and so on.

Social Networking Platform

The social networking platform project is best suited to intermediate Java programmers. You may devise a social networking platform in Java that includes all of the essential elements, such as a chatbox, calling features, posting images, likes, comments, and sharing of posts, a friend request module, and so on. You can also choose to include any extra special features or functions in the project.

Meanwhile, you may use Java's numerous APIs to make things easier and more convenient. However, in order to complete the social networking platform project, you must have a deep understanding of several other disciplines, including computer networking, databases, and a variety of others, in addition to your Java language skills.

Number Guessing Game

This is a simple project that you can complete quickly and add to your portfolio, especially if you are a novice. In the number guessing game, you must create an app that generates a random number that the user must guess. Users will receive points if they guess correctly.

The rules of the number guessing game are completely up to you. For example, you may set a limit on the number of attempts, choose a range for number generation, and award points based on the number of attempts, among other things.

In the number guessing game, the computer must generate a random number from 1 to 100 that falls within the set range.

After that, the user is asked to guess the number and enter it in an input area. After comparing the generated number with the user's input, the user will receive a message indicating whether their guess was correct or incorrect with respect to the randomly created number.

Snake Game

Java is a sophisticated programming language with the added bonus of being able to build games with it. In fact, you might be interested to know that one of the most famous sandbox games, Minecraft, was built using Java. Nevertheless, this Java project demands that you create a classic 2D snake game similar to those you may have played as a kid.

Building the snake game will allow you to understand and use many Java principles. To develop the snake game efficiently, you'll also need to apply object-oriented programming techniques. You must make sure that the snake figure can be moved in all four directions by the player and that the snake food appears at random locations across the play area. You should additionally take care if the snake acquires or eats food, its length will increase. Also, the gaming session should end as the snake reaches the edge of the playing region or bumps into its own body.

Online Survey Tool

Surveys allow businesses to garner crucial information from customers. This information can help the business to curate sound marketing strategies and iterate products or services to resolve the pain points of clients.

For this survey tool, you'll use many Java concepts to set up a new survey system that companies can use to create and distribute surveys to consumers. Customers can be emailed the results of the surveys if the tool allows it.
You may also use it to restrict access to certain surveys to certain users or clients. When developing such a system, such as MySQL or PostgreSQL, you must utilise a database management system (DBMS) to store the data.

Surveys help companies get vital information from customers that can aid in the development of apt marketing strategies, the modification of products or services to match specific customer needs, and so on.

Traffic Controller

Beginner and intermediate Java programmers should consider working on the traffic controller system project. The goal of this project is to devise an automated system for traffic control management. This project will have multiple modules to execute various operations such as traffic light control, traffic route management, traffic police supervision for a certain area, and so on.

Furthermore, with a solid understanding of other topics such as OOPs, Servlets, and so on, you may develop the traffic controller system project in Java using JSPs and MySQL. You may even take the project to the next level by adding more complex functionality and using Spring, Hibernate, and other technologies.

Digital Clock

This is a project for amateurs that can be executed in a short amount of time. You're probably familiar with the concept of a digital clock. You only need to display the current time on the digital clock you're working on. Your digital clock can display seconds in addition to minutes and hours.

Displaying the day of the week and the date on your digital clock will give it more utility. A timer, a stopwatch, and a timezone are just a few of the other functions that may be added to the digital clock.

To build a digital clock, you'll need to be well versed in user interface design, as your digital clock will need to be aesthetically attractive. To make everything simple, you could devise a digital clock that has a simplistic style.

Temperature Convertor

If you're new to Java, creating a temperature converter is a fantastic project to get started. A temperature conversion application's principle is simple: it should convert temperatures from Fahrenheit to Celsius and vice versa.

The mathematical equation for translating temperature from Fahrenheit to Celsius and Celsius to Fahrenheit is the first thing you need to learn to construct this application. You must design an interface with one input field, a "Convert" button, a section that displays the output, and another button that allows the user to switch from Celsius to Fahrenheit.

You can also include a code to respond to an inappropriate input. If a user enters a non-numerical value, the converter should produce a message like "Invalid Input."

System for Student Management

Your CV would greatly benefit from a student management system. You will find it easier to construct this project if you have already built a few beginner-level Java projects.

A student management system, in general, allows a school administration to manage students and optimise numerous operations, such as student enrollment and course feedback.

You must divide a student management system into various sections or modules in order to make it effective. For example, the system can be divided into three main modules: administrator, student, and teacher. In addition, all these modules must have their own interface.

One or more people can use the administrator interface to take control of the entire system. In other words, an administrator has the ability to manage student and teacher accounts, monitor all data, and enable or disable services that are available to students and teachers.

The student module manages student accounts and allows students to log in, post assignments, check comments, and score, among other things. Teachers can also log in to their accounts, to monitor student attendance, check submitted assignments, and upload exam results.

Customer Relationship Management (CRM) Software

This is one of the more difficult Java projects, requiring a thorough understanding of several Java principles as well as previous experience working on a variety of Java projects. Contact management, workflow automation, lead management, and quote and order management are just a few of the capabilities of a CRM (Customer Relationship Management) system.

A CRM's primary goal is to assist a company in boosting sales, providing efficient customer service, and effectively interacting with customers.

To make the whole thing more manageable, you should develop a distinct module for each function you add to your CRM. Multiple users should be able to create accounts under a single corporate entity, while having access to customer queries and other data using the CRM.

In general, there are a number of functions that you can include in your CRM. Keep in mind, however, that the more features you add to the CRM, the more complicated it will become, so plan accordingly.

Billing System

One of the most popular projects for refining your Java programming skills is the billing system. The basic objective of this billing system project is to automatically compute bills, eliminating the need for manual calculations. You might want to start by creating a simple interface that requires the user to enter the invoice number, price per unit, and number of units.

The system will generate a bill based on these facts, including the actual amount that must be paid. The wonderful thing about creating a billing system project in Java is that you may change the project's level from amateur to advanced depending on your skills and requirements. You can, for instance, create more complicated projects such as grocery billing systems, apparel billing systems, or electricity billing systems.

Supply Chain Management Software

Clients can directly communicate their item requirements to the manufacturer, who then contacts a number of vendors to obtain the necessary materials. Vendors typically make a list of items based on the items given to them, after which the manufacturer chooses the materials that best suit the client's specifications. The chosen list of components is delivered to the stock division for processing, after which the assembly process begins. When the work is finished, the records office adds up the cost of the raw materials and the cost of gathering them to produce the total bill. Finally, the customer receives the goods along with a receipt.

Summary
