Have you used the setter method in your projects?

Yes, the setter method is widely used in projects for access control and modifying object property values.

Setters allow:

• Encapsulating logic when changing a value (e.g., validation, data transformation).
• Tracking changes (e.g., notifying other components about the value change).
• Ensuring data security and integrity.

Example in Java:

public class User {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        if(name != null && !name.isEmpty()) {
            this.name = name;
        } else {
            throw new IllegalArgumentException("Name cannot be empty");
        }
    }
}

In QA automation, setters can be used to set values in data models or during test data preparation.
