Basic Java Projects with Source Code

Java is a popular programming language used to develop a wide range of applications, from simple games to complex systems. As a beginner, it's essential to start with basic projects that help you understand the syntax and concepts of Java. In this article, we'll explore some of the most popular basic Java projects with source code.

Online Quiz Application

The online quiz application is one of the simplest Java projects for beginners. This project involves creating a GUI-based application where users can take quizzes online. The project includes features such as:

* Creating a GUI using JFrame and JLabel

* Adding radio buttons to select answers

* Implementing if/else statements to check user answers

* Displaying results

Here's the source code for the Online Quiz Application:

```java

import java.awt.*;

public class OnlineQuiz {

public static void main(String'' args) {

JFrame f = new JFrame('Online Quiz');

f.setSize(500, 400);

f.setLayout(new FlowLayout());

JLabel ll = new JLabel(new ImageIcon('url.JPEG'));

ll.setFont(new Font('Casteller', Font.BOLD, 30));

f.add(ll);

JRadioButton ī1 = new JRadioButton('Uniform Resource Locator');

JRadioButton ī2 = new JRadioButton('Uniform Resource Link');

JRadioButton ī3 = new JRadioButton('Uniform Registered Link');

JRadioButton ī4 = new JRadioButton('Unified Resource Link');

f.add(ī1);

f.add(ī2);

f.add(ī3);

f.add(ī4);

JButton ī5 = new JButton('WELCOME TO ONLINE QUIZ');

f.add(ī5);

}

```

Billing System

The billing system is another popular Java project that involves calculating bills automatically. This project includes features such as:

* Reading input from the user

* Performing calculations based on user input

* Displaying results

Here's the source code for the Billing System:

```java

import java.util.*;

public class BillingSystem {

public static void main(String'' args) {

Scanner scanner = new Scanner(System.in);

double amount = scanner.nextDouble();

double tax = 0.1 * amount;

double total = amount + tax;

System.out.println('Total: ' + total);

}

```

Snake Game

The snake game is a classic Java project that involves developing a game using OOPs concepts and Swing. This project includes features such as:

* Creating a GUI using JFrame and JPanel

* Implementing game logic using loops and if/else statements

* Displaying game results

Here's the source code for the Snake Game:

```java

import javax.swing.*;

public class SnakeGame {

public static void main(String'' args) {

JFrame f = new JFrame('Snake Game');

f.setSize(500, 400);

JPanel panel = new JPanel();

panel.setLayout(new FlowLayout());

JButton up = new JButton('Up');

JButton down = new JButton('Down');

JButton left = new JButton('Left');

JButton right = new JButton('Right');

panel.add(up);

panel.add(down);

panel.add(left);

panel.add(right);

f.add(panel);

}

```

These are just a few examples of basic Java projects with source code that can help you get started with your Java journey. Remember to practice and experiment with different ideas to improve your skills and become proficient in Java programming.
