What are the best practices for getters and setters in programming?

Best practices for getters and setters include keeping them simple, using them for encapsulation, and avoiding complex logic.

Can you give an example of a good getter and setter?

Sure! Here's a simple example in Java:

private int age;

public int getAge() {
    return age;
}

public void setAge(int age) {
    if (age > 0) {
        this.age = age;
    }
}

This ensures that age cannot be set to a negative value.

Why should I avoid complex logic in getters and setters?

Complex logic can lead to unexpected side effects and make your code harder to maintain. Keep them straightforward!

Are there situations where I shouldn't use getters and setters?

Yes, if the class is a simple data structure or if you're using public fields, getters and setters may be unnecessary.
