- Enter a project name (e.g., “MyFirstJavaProject”).
- Ensure that the “Use default location” checkbox is selected, and click Finish.
4. Create a New Java Class
Now that you have a project, you can create a Java class:
- Right-click on the src folder in your project.
- Select New > Class.
- Enter a name for your class (e.g., “HelloWorld”).
- Check the box for public static void main(String[] args) to create the main method automatically.
- Click Finish.
Writing and Running Your Java Code
5. Write Your Java Code
In the newly created class, you can write your Java code. For example, to print “Hello, World!” to the console, enter the following code:
public class HelloWorld { public static void main(String[] args) { System.out.println("Hello, World!"); } } 6. Run Your Java Program
To run your program, follow these steps:
- Right-click on the file in the Package Explorer.
- Select Run As > Java Application.
- You should see “Hello, World!” printed in the Console view at the bottom of the IDE.
Exploring Eclipse IDE Features
Eclipse IDE offers a variety of features that can significantly enhance your productivity as a Java developer.
7. Code Completion and Suggestions
Eclipse provides intelligent code completion, which suggests methods, variables, and classes as you type. This feature can save you time and help you avoid errors. Simply start typing, and Eclipse will display a list of suggestions.
8. Debugging Your Code
Debugging is an essential skill for any developer. Eclipse has a powerful debugging tool that allows you to set breakpoints, step through your code, and inspect variables. To debug your program:
- Set a breakpoint by double-clicking in the left margin next to the line number.
- Right-click on your file and select Debug As > Java Application.
- Use the Debug perspective to control the execution flow and examine variable values.
9. Using Plugins
Eclipse has a rich ecosystem of plugins that can extend its functionality. You can install plugins for version control (like Git), build tools (like Maven), and more. To install a plugin:
- Go to Help > Eclipse Marketplace.
- Search for the desired plugin and click Go.

Best Practices for Java Development in Eclipse
10. Organizing Your Projects
Keep your projects organized by using packages. Right-click on the src folder, select New > Package, and give it a name. This helps in managing your classes and avoiding naming conflicts.
11. Version Control Integration
Integrating version control into your workflow is crucial for collaboration and code management. Eclipse supports Git through the EGit plugin. You can clone repositories, commit changes, and manage branches directly from the IDE.
12. Regularly Update Eclipse
Eclipse frequently releases updates that include new features, bug fixes, and performance improvements. To check for updates, go to Help > Check for Updates.
