Which method allows a developer to access private class attributes in Java?

• A. Static methods
• B. Setter methods
• C. Getter methods
• D. Final methods

Answer: (C)

The correct answer is getter methods. Getter methods in Java are specifically designed to provide access to the private attributes of a class. By defining a public method that returns the value of a private variable, a developer can encapsulate the internal state of the class while still allowing outside code to retrieve those values when needed.

For example, if a class has a private attribute called age, a corresponding getter method might look like this:

public int getAge() {

return age;

}

Using this method, other classes can call getAge() to obtain the value of age, even though it is private and cannot be accessed directly. This approach aligns with the principles of encapsulation in object-oriented programming, where data is kept safe while still being accessible when appropriate.

Setter methods, while also commonly used to access private attributes, serve a different purpose. They allow modification of those attributes rather than simply accessing their values. Static and final methods do not offer means to access private attributes; static methods belong to the class level rather than instances of the class, and final methods cannot be overridden but do not directly relate to accessing private fields.
