How can I identify and fix code smells in my project?

Code smells are indicators of potential issues in your code. You can identify them by looking for things like long methods, large classes, or duplicated code. Would you like to know more about specific types of code smells?

Yes, what are some common types of code smells?

Some common code smells include:

1. Long Method: A method that is too long and does too much.
2. Large Class: A class that has too many responsibilities.
3. Duplicated Code: The same code appearing in multiple places.
4. Feature Envy: A class that is more interested in another class's data than its own. Would you like tips on how to fix any of these?

How do I fix duplicated code?

To fix duplicated code, you can refactor it by extracting the common code into a separate method or class. This way, you can call that method or class wherever needed, reducing redundancy. Would you like to see an example?

Yes, please provide an example of refactoring duplicated code.

Sure! If you have two methods that look like this:

public void methodA() {
    // duplicated code
    System.out.println("Hello, World!");
}

public void methodB() {
    // duplicated code
    System.out.println("Hello, World!");
}

You can refactor it like this:

public void printHello() {
    System.out.println("Hello, World!");
}

public void methodA() {
    printHello();
}

public void methodB() {
    printHello();
}

This way, you only have one place to change the code if needed!
