Java basics to practical applications: Selection of practical projects

Java is a powerful and versatile programming language that is widely used in a variety of industries. For Java beginners, the transition from basic knowledge to practical application can be challenging. To help you get started smoothly, this article provides a selection of practical projects to help you consolidate the knowledge you have learned and build practical project experience.

Entry Level Project

• Addition Calculator: Create a simple command line program that prompts the user to enter two numbers and prints them Its sum.
• Average Calculator: Create an interactive program that prompts the user to enter a series of numbers and calculates the average.
• Determine prime numbers: Develop a program that lets the user enter a number and check whether it is prime.
• Dice Rolling Simulator: Create a virtual dice using a random number generator and print the result of the dice rolling.

Junior Project

• Student Grade Management System: Build a command line interface application that allows users to enter student information (name, grades, etc.) and provide basic operations (add, delete, search).
• File read and write operations: Create a program that can read data from a file and write it to a new file.
• Object-oriented programming: Create a class and object that represents a geometric shape (such as a circle or square), and add methods to the object to calculate the area and perimeter.

Intermediate Project

• Weather Forecast Application: Use API or Web service to obtain weather data and create a command line Interface application to display current weather conditions.
• Data structure implementation: Implement the most commonly used data structures in Java, such as stacks, queues and hash tables.
• Multi-threaded programming: Create a multi-threaded program to perform different tasks in different threads to demonstrate the concepts of concurrency and synchronization.

Advanced Project

• GUI Development: Create a graphical user interface (GUI) application using Swing or JavaFX framework , providing an interactive user interface.
• JDBC connection database: Create a program that can connect to a relational database and perform query and update operations.
• Web Development: Create a simple web application using Servlet, JSP or Spring Boot framework to handle HTTP requests and generate dynamic web pages.

By working on these practical projects, you can gain an in-depth understanding of core Java concepts such as data types, control flow, object-oriented programming, data structures, and file processing. You'll also hone your problem-solving, programming, and debugging skills to prepare you for a career path in Java.
