Example

This example shows how to create a simple Java project and add a class with a main method that prints a message.

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, Eclipse Java Project!");
    }
}

Output

Hello, Eclipse Java Project!

Common Pitfalls

Some common mistakes when creating a Java project in Eclipse include:

• Not selecting Java Project and choosing a different project type.
• Forgetting to add a src folder or Java class, so the project has no runnable code.
• Not setting the correct JRE system library, which can cause compilation errors.

Always verify your project has a src folder and a Java class with a main method to run.

java

/* Wrong: Creating a project without Java nature */
// This leads to no Java build path and errors.

/* Right: Use File > New > Java Project to ensure proper setup */

Quick Reference

Step	Action

Key Takeaways

Use File > New > Java Project to create a new Java project in Eclipse.

Always add a src folder and Java class with a main method to run your code.

Check the JRE system library is set correctly to avoid build errors.

Naming your project clearly helps organize your workspace.
